When to Get Vision and Hearing Tests – Age Based Schedule

By Roel Feeney | Published Sep 03, 2022 | Updated Sep 03, 2022 | 41 min read

Children should have their first vision screening at birth and their first formal hearing test by age 1. Adults need vision exams every 1 to 2 years starting at age 18, and hearing evaluations every 10 years until age 50, then every 3 years after that. Catching problems early prevents long-term damage to learning, communication, and quality of life.

The Newborn Window: What Happens Before You Leave the Hospital

Newborn hearing screening, a quick non-invasive test that measures how the inner ear responds to sound, is performed on more than 97% of U.S. babies before hospital discharge. The American Academy of Pediatrics (AAP) requires this screening to happen within the first 30 days of life, ideally within the first 2 days.

Vision screening at birth focuses on detecting structural problems such as cataracts (clouding of the eye lens), corneal abnormalities, and pupil response issues. Pediatricians use a penlight and red reflex test (a check for normal light reflection from the retina, similar to red-eye in photos) during the standard newborn exam.

Babies who fail the initial hearing screen must receive a diagnostic audiology evaluation by age 3 months and, if hearing loss is confirmed, intervention must begin no later than age 6 months to protect speech development. This three-part framework is called the EHDI 1-3-6 model (Early Hearing Detection and Intervention), the national standard in the United States.

Two Types of Newborn Hearing Screens

Hospitals use one of two technologies for the newborn hearing screen, and parents should understand which one their child received:

  1. OAE (Otoacoustic Emissions) Screening: A small probe placed in the ear canal plays soft sounds and measures the echo produced by healthy inner ear hair cells. Takes less than 5 minutes. Does not require the baby to be still or awake.
  2. ABR (Auditory Brainstem Response) Screening: Electrodes placed on the baby’s scalp measure electrical activity in the auditory nerve and brainstem in response to clicking sounds. More comprehensive and used when OAE results are unclear.

A failed OAE screen does not confirm hearing loss. Fluid in the ear canal, debris, or a crying baby can all produce a failed result. Approximately 2 to 10% of newborns fail the initial screen, but only about 1 to 3 per 1,000 are ultimately confirmed to have permanent hearing loss. This is why follow-up diagnostic testing is required before any diagnosis is made.

What the Red Reflex Test Actually Reveals

The red reflex test, performed with an ophthalmoscope (a handheld instrument that shines light into the eye), normally produces a symmetrical orange-red glow from both pupils. An absent, white, or asymmetric reflex signals a potentially serious condition and requires immediate ophthalmology referral.

Conditions detected through an abnormal red reflex include:

  • Congenital cataracts (lens clouding present from birth).
  • Retinoblastoma (a rare but serious childhood eye cancer affecting approximately 1 in 16,000 to 18,000 births in the U.S.).
  • Congenital glaucoma (elevated eye pressure present from birth).
  • Corneal abnormalities.
  • Significant refractive errors causing unequal light return.

Retinoblastoma is worth particular attention because early detection through a failed red reflex exam can be genuinely life-saving. Survival rates exceed 95% when the cancer is caught before it spreads outside the eye.

Infant and Toddler Milestones: Ages 6 Months to 3 Years

Vision and hearing development is rapid in the first three years of life, making scheduled evaluations during this period critically important for catching problems before they disrupt language acquisition.

Hearing Checkpoints in the First Three Years

  1. By age 6 months: Baby should startle at loud sounds, turn toward voices, and babble.
  2. By age 12 months: Child should say at least one word, recognize their name, and respond to simple commands.
  3. By age 2 years: Child should use at least 50 words and begin combining two-word phrases.

A child who misses these milestones should be referred immediately to a licensed audiologist (a specialist in hearing disorders and rehabilitation) for a full diagnostic hearing test, regardless of any previously passed newborn screen. Approximately 25% of children with confirmed hearing loss passed their newborn screen, meaning a clear screen at birth does not rule out later-onset or progressive hearing loss.

Causes of Hearing Loss That Appear After a Passed Newborn Screen

Several types of hearing loss develop after birth and will not be caught by a newborn screen, even a well-performed one:

  • Enlarged vestibular aqueduct (EVA): A structural inner ear abnormality (the vestibular aqueduct is a small bony canal connecting the inner ear to the brain) that can cause fluctuating and progressive hearing loss triggered by head injury or illness, often first detected in toddlerhood.
  • Cytomegalovirus (CMV): The most common non-genetic cause of childhood hearing loss in the U.S. CMV (a common virus in the herpesvirus family) causes approximately 25% of all childhood hearing loss cases. Hearing loss from congenital CMV can be present at birth or develop in the first few years of life.
  • Auditory neuropathy spectrum disorder (ANSD): A condition where sound reaches the inner ear normally but the signal transmission to the brain is disrupted. Some cases pass OAE screening because the outer hair cells are intact.
  • Meningitis: Bacterial meningitis can destroy inner ear structures within days. Children who survive bacterial meningitis should receive an urgent audiological evaluation within 4 weeks of discharge because cochlear ossification (hardening of the inner ear) can begin quickly, affecting candidacy for cochlear implants.
  • Genetic causes with delayed onset: More than 400 genetic syndromes are associated with hearing loss, and not all present at birth.

Vision Development Tracking

The AAP recommends vision screenings at every well-child visit from infancy through adolescence. Specific checkpoints include:

  • Age 6 months: Eye alignment check and tracking assessment.
  • Age 12 months: Red reflex re-evaluation.
  • Age 3 years: First photoscreening or visual acuity (sharpness of sight) test using age-appropriate charts.

Key Finding: Amblyopia (lazy eye, a condition where the brain favors one eye, reducing vision in the other) affects 2 to 3 out of every 100 children in the U.S. and is most successfully treated before age 7. Routine screenings at age 3 and again at age 5 are the primary mechanism for catching it early.

Photoscreening: What It Is and Why It Matters for Young Children

Photoscreening is a technology that uses digital photography to detect risk factors for vision problems in children who are too young to read an eye chart. A camera takes a photo of the child’s eyes, and the image is analyzed for signs of refractive error, amblyopia risk, and eye misalignment.

Photoscreening is particularly valuable because it can be used in children as young as 6 months, takes only seconds to perform, does not require the child’s cooperation, and can be used by trained non-physician staff. Instruments such as the Spot Vision Screener and the Welch Allyn Suresight are FDA-cleared devices commonly used in pediatric offices across the U.S.

The AAP endorses photoscreening as an acceptable alternative to visual acuity testing for children aged 12 months to 3 years when standard chart testing is not possible due to age or developmental level.

Preschool Through Elementary School: Ages 3 to 10

Children aged 3 to 5 should receive a comprehensive vision screening that includes visual acuity testing at 20 feet using a standardized eye chart adapted for pre-readers (such as the HOTV or tumbling E chart). The target passing threshold at this age is 20/40 or better in each eye.

By age 5 to 6, the standard sharpens. Children should see 20/30 or better, and any child still below 20/40 should be referred to a pediatric ophthalmologist (a physician specializing in children’s eye diseases and surgery).

What School Vision Screenings Can and Cannot Detect

School-based vision screenings, conducted by nurses or trained staff, are a valuable first filter but are not a substitute for a comprehensive eye exam performed by an optometrist or ophthalmologist.

What School Screenings DetectWhat School Screenings Miss
Basic distance visual acuity problemsNear vision deficits (difficulty reading up close)
Significant refractive errors (nearsightedness, farsightedness)Early glaucoma (increased eye pressure)
Obvious eye misalignmentColor vision deficiencies
Gross amblyopiaConvergence insufficiency (difficulty using both eyes together)
Gross amblyopia risk factorsAccommodative esotropia (eye crossing caused by farsightedness)
Gross color vision problems in some protocolsEarly keratoconus (progressive thinning of the cornea)

State-by-State Variability in School Screening Requirements

Vision and hearing screening requirements vary considerably by state. There is no single federal mandate governing school-based screening protocols.

  • All 50 states require some form of school vision screening, but the frequency, age requirements, and referral criteria differ.
  • Some states require vision screenings only at kindergarten entry.
  • Other states require screenings at 5 or more grade levels (kindergarten, first, second, third, fifth, seventh, and tenth grade, for example).
  • Hearing screening grade requirements similarly vary, with most states mandating screenings at kindergarten and at least 3 additional grade levels through high school.

Parents should contact their child’s school district or state health department to confirm the specific screening schedule in their state, and should not assume that a school screening serves as a substitute for a clinical examination when a child shows academic struggles, complaints of headaches, or behavioral changes that may indicate sensory problems.

Strabismus: Why Alignment Matters Beyond Appearance

Strabismus (misalignment of the eyes, where one or both eyes turn inward, outward, upward, or downward) affects approximately 4% of U.S. children. It is important not only because it affects appearance, but because misaligned eyes can lead directly to amblyopia if the brain begins suppressing the image from the turned eye.

Treatment options depend on the type and severity of strabismus and may include glasses, patching, eye drops containing atropine (a medication that blurs the stronger eye to force the weaker one to work), or surgery to realign the eye muscles. Treatment is most effective when started before age 7, though benefits have been documented in older children and even adults under certain protocols.

Hearing tests in public schools are required in most U.S. states at specific grade levels, typically kindergarten, first grade, second grade, third grade, and fifth grade. These are pure-tone audiometry screenings (tests using tones at specific frequencies to find the quietest sound a person can hear) conducted at 500, 1000, 2000, and 4000 Hz.

Interpreting a School Hearing Screening Referral

A referral from a school hearing screen means the child did not respond to at least one tone at the standard threshold level (20 decibels in most protocols) in one or both ears. This is not a diagnosis of hearing loss. Common reasons for a referral include:

  • Ear wax blockage (cerumen impaction).
  • Fluid behind the eardrum from a recent cold or ear infection (otitis media with effusion).
  • Noisy testing environment causing inaccurate results.
  • True sensorineural hearing loss (permanent damage to the inner ear or auditory nerve).

A referral should be followed up with a visit to the child’s pediatrician first to rule out reversible causes, and then with a full audiological evaluation if the problem persists.

Adolescent Years: Ages 11 to 17

Myopia (nearsightedness, meaning difficulty seeing distant objects clearly) peaks during adolescence due to rapid eye growth. Research published by the American Optometric Association shows that myopia prevalence increases sharply between ages 8 and 16 and is now present in approximately 42% of Americans, up from 25% in the 1970s.

The recommended schedule for adolescents with no known vision problems is a comprehensive eye exam every 1 to 2 years. Teens who already wear glasses or contact lenses should be seen annually to update their prescription and monitor eye health.

Myopia Management: A Rapidly Evolving Field

Standard glasses and contact lenses correct myopia but do not slow its progression. Myopia management, meaning interventions specifically designed to reduce the rate at which myopia worsens, has become a meaningful clinical priority in the U.S. over the past decade.

Evidence-supported myopia management strategies currently in use include:

StrategyMechanismEvidence Level
Low-dose atropine eye drops (0.01% to 0.05%)Relaxes eye growth signals through muscarinic receptor actionStrong; multiple large randomized trials
Orthokeratology (ortho-k)Rigid contact lenses worn overnight that temporarily reshape the corneaModerate to strong
Multifocal soft contact lensesPeripheral defocus design that slows axial eye growthModerate; FDA-cleared options available
Increased outdoor timeBelieved to involve bright light stimulating dopamine release in the retina, which slows eye elongationModerate; at least 2 hours outdoors daily is recommended

Children with myopia that is progressing rapidly (more than 0.75 diopters per year, where a diopter is the unit measuring lens power) are typically the best candidates for active myopia management. Parents should discuss this with a pediatric optometrist or ophthalmologist.

Hearing loss in teens deserves serious attention. The National Institute on Deafness and Other Communication Disorders (NIDCD) reports that approximately 1 in 5 teenagers in the United States has some degree of hearing loss. Noise-induced hearing loss (NIHL), permanent damage to the hair cells of the inner ear caused by exposure to loud sound, is largely preventable and largely underdiagnosed in this age group.

The 60/60 Rule for Safe Headphone Use

The 60/60 rule is a practical guideline endorsed by audiologists and hearing health organizations for reducing NIHL risk from personal audio devices:

  • Listen at no more than 60% of maximum volume.
  • For no more than 60 minutes at a time.
  • Take a break of at least several minutes between listening sessions.

At 85 decibels (roughly the volume of city traffic), OSHA’s occupational guidelines permit 8 hours of exposure before damage risk begins. At 100 decibels (common smartphone maximum output through earbuds), safe exposure time drops to less than 15 minutes.

Teens who frequently use headphones at high volumes, attend concerts, or participate in loud recreational activities should have hearing evaluations annually rather than waiting for symptoms.

Adults Ages 18 to 39: Building the Baseline

Young adults without risk factors or symptoms need a baseline comprehensive eye exam performed by age 18 if one was not completed during adolescence. After establishing this baseline, healthy adults in this age range can be screened every 2 years by an eye care professional.

Adults who wear corrective lenses, have a family history of glaucoma or macular degeneration (age-related deterioration of the central retina), or have diabetes or hypertension should move to annual exams regardless of age.

Contact Lens Wearers Need Annual Exams Regardless of Age

Contact lens wearers in any age group face a unique set of risks that make annual eye exams medically necessary rather than simply recommended. These risks include:

  • Corneal neovascularization (abnormal blood vessel growth into the clear cornea, caused by chronic oxygen deprivation from lens overwear).
  • Giant papillary conjunctivitis (GPC): An immune reaction to protein deposits on the lens surface causing large bumps under the upper eyelid.
  • Microbial keratitis (infection of the corneal tissue, which can cause permanent scarring): Extended wear and poor hygiene practices dramatically increase risk.
  • Prescription drift: Myopia in particular can continue changing into the mid-20s, making an outdated prescription both a vision problem and a safety hazard when driving.

The FDA recommends that contact lens prescriptions be renewed annually to ensure fit, lens material, and power remain appropriate.

Hearing screening for healthy adults aged 18 to 39 is recommended at least once per decade by the American Speech-Language-Hearing Association (ASHA). This baseline audiogram (a graphic chart of hearing ability across sound frequencies) serves as a crucial reference point for detecting future changes.

Important: A baseline audiogram is most useful when it is performed while hearing is still normal or near-normal. Waiting until you notice symptoms means the comparison data is already compromised.

Musicians, Concertgoers, and Occupational Noise Exposure in Young Adults

Young adults in music, construction, agriculture, manufacturing, nightlife service industries, and the military face substantially elevated hearing loss risk that warrants annual audiological evaluation regardless of the general population schedule.

  • Sound levels at live concerts routinely reach 110 to 120 decibels, exceeding safe exposure thresholds within less than 2 minutes.
  • Firearms produce 140 to 165 decibels per shot without hearing protection, enough to cause immediate and permanent damage from a single exposure.
  • Custom musician earplugs (filtered earplugs that reduce overall volume while preserving sound fidelity) are now widely available and recommended for anyone attending or performing live music regularly.

The 40 to 64 Age Range: When Risk Accumulates

The likelihood of developing presbyopia (age-related loss of near focus, the reason many adults need reading glasses after age 40) rises sharply in this decade. This is also the window during which early open-angle glaucoma (the most common form, which develops slowly and painlessly, often without noticeable symptoms until significant vision is lost) becomes a meaningful risk.

The American Academy of Ophthalmology recommends the following schedule for adults 40 to 64:

Age RangeRecommended Eye Exam Frequency
40 to 54 (no risk factors)Every 2 to 4 years
40 to 54 (with risk factors)Annually
55 to 64 (no risk factors)Every 1 to 3 years
55 to 64 (with risk factors)Annually

Risk factors that move an adult into the more frequent category include:

  • African American ancestry (glaucoma risk is 3 to 4 times higher in this population).
  • Family history of glaucoma or macular degeneration.
  • Diabetes or hypertension.
  • Steroid medication use (long-term corticosteroids raise intraocular pressure).
  • Previous eye injury or surgery.
  • High myopia (prescriptions above -6.00 diopters carry elevated retinal detachment and glaucoma risk).
  • Hispanic ancestry (elevated glaucoma risk, particularly for open-angle glaucoma).

Understanding the Glaucoma Screening Gap

Glaucoma is frequently called the “silent thief of sight” because it causes no pain and produces no symptoms until 40 to 50% of optic nerve fibers have already been destroyed. By the time a person notices peripheral vision loss, the damage is permanent and irreversible.

The only reliable way to detect glaucoma before significant vision loss occurs is through a comprehensive eye exam that includes:

  • Tonometry (measuring intraocular pressure, where normal is generally 10 to 21 mmHg).
  • Ophthalmoscopy (direct visualization of the optic nerve head for signs of damage).
  • Visual field testing (a computerized test mapping the full scope of peripheral vision).
  • OCT imaging (optical coherence tomography, a non-invasive scan that produces cross-sectional images of the retina and optic nerve fiber layer with micrometer precision).

Intraocular pressure alone is an imperfect screening tool. Approximately 30 to 40% of people with glaucoma have pressures in the normal range (a condition called normal-tension glaucoma), and many people with elevated pressure never develop glaucoma. Comprehensive structural and functional assessment is required.

For hearing, adults in the 40 to 64 range should be tested every 3 to 5 years if no problems are present. Those exposed to occupational noise (construction, manufacturing, military service, music performance) should be tested annually and are protected by OSHA (the Occupational Safety and Health Administration) hearing conservation regulations requiring employer-provided audiometric testing when noise exposure exceeds 85 decibels averaged over an 8-hour workday.

Tinnitus as a Warning Sign, Not Just a Nuisance

Tinnitus (ringing, buzzing, hissing, or roaring sounds perceived in the ears or head without an external source) affects approximately 15% of American adults, making it one of the most common health conditions in the country. The American Tinnitus Association estimates that more than 45 million Americans experience tinnitus.

Persistent tinnitus is frequently an early indicator of underlying cochlear damage (damage to the hearing structures of the inner ear) and should always prompt a formal audiological evaluation. Tinnitus does not necessarily mean severe hearing loss is present, but in many cases it precedes measurable threshold changes on an audiogram by months or years.

A comprehensive tinnitus evaluation typically includes:

  1. Full audiological assessment including high-frequency testing (above 8,000 Hz).
  2. Tinnitus pitch and loudness matching.
  3. Minimum masking level determination.
  4. Medical history review to rule out treatable causes (earwax, otosclerosis, acoustic neuroma, medication side effects, cardiovascular conditions).

Age 65 and Older: Annual Evaluations Become the Standard

Adults 65 and older should receive a comprehensive dilated eye exam, meaning eye drops are used to widen the pupil so the physician can fully examine the retina and optic nerve, every year without exception.

The four leading age-related eye conditions that annual exams are designed to detect are:

  1. Age-Related Macular Degeneration (AMD): Affects the central retina and is the leading cause of vision loss in Americans over 50.
  2. Glaucoma: Affects an estimated 3 million Americans, with half unaware they have it.
  3. Cataracts: Present in more than 50% of Americans by age 80.
  4. Diabetic Retinopathy: Affects more than 7.7 million Americans and is the leading cause of new blindness in working-age adults.

AMD: Dry vs. Wet and What Monitoring Requires

Age-related macular degeneration exists in two forms, and understanding the difference is important for patients managing their screening schedule.

Dry AMD (atrophic AMD) accounts for approximately 85 to 90% of all AMD cases. It progresses slowly through the accumulation of drusen (yellow deposits beneath the retina) and gradual thinning of the retinal pigment epithelium. There is currently no FDA-approved treatment that halts dry AMD progression, though the AREDS2 supplement formula (a specific combination of vitamins C and E, lutein, zeaxanthin, and zinc) has been shown to reduce the risk of progression to advanced AMD by approximately 25% in people with intermediate or advanced dry AMD.

Wet AMD (neovascular AMD) accounts for approximately 10 to 15% of cases but causes the majority of severe central vision loss. It involves abnormal blood vessel growth beneath the retina (choroidal neovascularization) that leaks fluid and blood. Anti-VEGF injections (medications that block vascular endothelial growth factor, the protein driving abnormal vessel growth) have transformed wet AMD treatment, with regular injections into the eye capable of maintaining or even improving vision in many patients.

People with dry AMD in one or both eyes should be monitoring themselves at home using an Amsler grid (a simple grid of horizontal and vertical lines used to detect distortion or blind spots in central vision) and reporting any sudden changes in their vision immediately, as conversion from dry to wet AMD can happen quickly.

Cataract Surgery: The Most Commonly Performed Surgery in the U.S.

Cataracts are not always immediately disabling. The decision to pursue cataract surgery (phacoemulsification, a procedure using ultrasonic vibration to break up and remove the clouded lens, which is then replaced with an artificial intraocular lens) is made based on functional impact rather than appearance alone.

Surgeons and patients typically consider surgery when cataracts interfere with:

  • Safe driving, particularly at night (glare and halos around lights).
  • Reading or near tasks despite updated glasses.
  • Occupational performance.
  • Quality of life in everyday activities.

Cataract surgery has a success rate exceeding 95% and typically takes fewer than 20 minutes per eye. Recovery is rapid, with most patients achieving functional vision within 24 to 48 hours. It is performed as an outpatient procedure.

For hearing, the data is clear and the gap between need and action is substantial. The NIDCD reports that 1 in 3 adults ages 65 to 74 has hearing loss, and nearly half of adults over 75 have significant hearing difficulty. Yet only about 1 in 5 Americans who could benefit from a hearing aid actually uses one.

The Cognitive Health Connection

Research has established a meaningful relationship between untreated hearing loss and cognitive decline. A landmark study from Johns Hopkins University found that mild hearing loss doubled the risk of dementia, moderate hearing loss tripled it, and severe hearing loss increased dementia risk by 5 times compared to people with normal hearing.

The mechanisms behind this connection are still being studied, but current theories include:

  • Cognitive load theory: The brain expends more resources compensating for poor hearing signal, leaving fewer resources available for memory and cognition.
  • Social isolation: Hearing loss leads to withdrawal from conversations and social engagement, a known risk factor for cognitive decline.
  • Auditory deprivation: Reduced stimulation of the auditory cortex may lead to structural and functional brain changes over time.

A 2023 randomized controlled trial (the ACHIEVE study) published in The Lancet found that hearing intervention in older adults at elevated risk for cognitive decline significantly slowed the rate of cognitive decline over a 3-year period, providing the strongest evidence to date that treating hearing loss may protect brain health.

Annual hearing evaluations for adults 65 and older are strongly recommended by ASHA and the National Council on Aging (NCOA). The evaluations should include pure-tone testing, speech recognition testing (measuring how well a person understands spoken words at a comfortable volume), and middle ear assessment.

Vestibular Testing in Older Adults

The vestibular system (the inner ear structures and brain pathways responsible for balance and spatial orientation) is closely linked to the auditory system and is often evaluated as part of a comprehensive audiological workup for older adults.

Falls are the leading cause of injury death in Americans 65 and older, and vestibular dysfunction (impaired balance function due to inner ear problems) is a significant contributor. The CDC reports that 3 million older adults are treated in emergency departments for fall injuries each year.

Testing for vestibular function may include:

  • VNG (videonystagmography): A test measuring eye movements to assess how well the inner ear and brain are working to control eye and body movements.
  • VEMP (vestibular evoked myogenic potentials): A test using sound to stimulate specific vestibular organs.
  • Rotary chair testing: Evaluation of how the eyes compensate for body rotation to assess bilateral vestibular function.

Older adults experiencing dizziness, vertigo (the sensation of spinning), or unexplained falls should request vestibular function testing as part of their audiological evaluation.

What Happens During These Tests

A comprehensive eye exam performed by an optometrist or ophthalmologist typically includes:

  • Visual acuity measurement using a Snellen chart (the standard letter chart with rows decreasing in size).
  • Refraction assessment to determine the precise prescription needed for glasses or contacts.
  • Intraocular pressure measurement (tonometry, a test that detects elevated pressure associated with glaucoma).
  • Dilated fundus exam to inspect the retina, optic nerve, and blood vessels.
  • Slit-lamp examination to assess the cornea, lens, and anterior structures of the eye.

A diagnostic hearing evaluation performed by an audiologist includes:

  • Pure-tone air and bone conduction testing to find hearing thresholds across frequencies.
  • Tympanometry (a test measuring how the eardrum moves, assessing middle ear function).
  • Speech audiometry to test recognition and understanding of spoken words.
  • Otoacoustic emissions testing (OAE, a test that measures sounds generated by healthy inner ear hair cells in response to sound stimulation).

How to Read Your Audiogram Results

An audiogram plots hearing thresholds (the quietest sound a person can hear at each frequency) on a graph. Understanding the basics helps patients participate meaningfully in their own care.

  • The horizontal axis represents frequency (pitch) in Hertz (Hz), typically ranging from 250 Hz (low-pitched sounds like a bass guitar) to 8,000 Hz (high-pitched sounds like a bird chirping). Normal speech occurs primarily between 500 and 4,000 Hz.
  • The vertical axis represents intensity (loudness) in decibels hearing level (dB HL), with 0 dB HL at the top representing the softest sound a person with normal hearing can detect. The scale typically extends to 120 dB HL at the bottom.
  • Hearing thresholds at 25 dB HL or better across all frequencies are generally considered within normal limits for adults.

Degree of Hearing Loss Classification

Threshold RangeDegree of LossPractical Impact
0 to 25 dB HLNormalNo significant difficulty
26 to 40 dB HLMildDifficulty with soft speech, distance, or noise
41 to 55 dB HLModerateDifficulty following normal conversation
56 to 70 dB HLModerately severeRequires amplification for most conversations
71 to 90 dB HLSevereSignificant reliance on visual cues and amplification
91+ dB HLProfoundVery limited hearing even with amplification; cochlear implant candidacy may be appropriate

How to Read Your Vision Prescription

An eyeglass prescription uses standardized notation that is consistent across all providers in the United States.

  • OD (oculus dexter) refers to the right eye; OS (oculus sinister) refers to the left eye; OU refers to both eyes together.
  • Sphere (SPH): The main lens power. A negative number indicates myopia (nearsightedness); a positive number indicates hyperopia (farsightedness). Measured in diopters.
  • Cylinder (CYL): The power needed to correct astigmatism (irregular curvature of the cornea or lens that causes blurred or distorted vision at all distances). May be zero if no astigmatism is present.
  • Axis: A number from 1 to 180 indicating the orientation of the cylinder correction in degrees.
  • Add power: The additional magnification added to the bottom of a bifocal or progressive lens for near vision. Typically appears in prescriptions for patients 40 and older.
  • Prism: Rarely included; used to correct eye alignment problems.

Insurance Coverage and Cost Considerations

Coverage for vision and hearing tests varies significantly across insurance types in the United States.

Vision coverage:

  • Medicare Part B covers one dilated eye exam per year for people with diabetes and for those at high risk for glaucoma, but does not cover routine eye exams for most adults.
  • Medicare Advantage plans often include routine vision benefits.
  • Medicaid generally covers routine vision exams for children under 21 through the EPSDT (Early and Periodic Screening, Diagnostic, and Treatment) program.
  • Routine comprehensive eye exams without insurance typically cost $100 to $300 depending on the provider and geographic area.

Hearing coverage:

  • Traditional Medicare does not cover routine hearing exams or hearing aids.
  • Medicare Advantage plans increasingly include hearing benefits.
  • An audiological diagnostic evaluation typically costs $250 to $350 without insurance.
  • Hearing aids can range from $1,000 to $7,000 per pair, though over-the-counter hearing aids became available in the U.S. in 2022 following an FDA ruling, with many options priced between $200 and $1,500.

Over-the-Counter Hearing Aids: Who They Are and Are Not For

The FDA’s 2022 rule creating an over-the-counter (OTC) hearing aid category represented the most significant change to U.S. hearing health access in decades. OTC hearing aids are self-fitting devices intended for adults 18 and older with mild to moderate hearing loss.

OTC hearing aids are not appropriate for:

  • Children under 18.
  • Adults with severe or profound hearing loss.
  • People with asymmetric hearing loss (significantly different between the two ears).
  • People with sudden or rapidly progressing hearing loss.
  • People with tinnitus as their primary complaint without accompanying hearing loss.
  • People with ear pain, drainage, or a history of ear surgery.

People in any of the above categories should see a licensed audiologist or otolaryngologist (a physician specializing in ear, nose, and throat disorders, also called an ENT) rather than attempting self-treatment with an OTC device.

The value of early detection is remarkable in every measurable dimension. Treating amblyopia at age 4 with a simple eye patch often costs a few hundred dollars. Treating the lifelong educational and occupational consequences of undetected vision loss costs far more in every dimension.

High-Risk Groups Who Need More Frequent Testing

Several populations face meaningfully elevated risk and should discuss customized screening schedules with their healthcare providers:

  • People with Type 1 or Type 2 diabetes should have a dilated retinal exam within 5 years of diagnosis for Type 1, and at the time of diagnosis for Type 2, then annually thereafter.
  • Veterans who served in high-noise environments (aviation, artillery, infantry) have among the highest rates of hearing loss and tinnitus of any population group in the U.S.
  • Premature infants and neonates with low birth weight face higher rates of both vision and hearing problems and require ophthalmological follow-up for retinopathy of prematurity (abnormal blood vessel growth in the premature retina) and audiological monitoring beyond the newborn screen.
  • People taking ototoxic medications (drugs that are harmful to the structures of the inner ear, including certain chemotherapy agents such as cisplatin, loop diuretics such as furosemide, and aminoglycoside antibiotics such as gentamicin) should receive baseline and follow-up audiograms throughout treatment.

Pregnancy and Vision Changes

Pregnancy produces temporary but notable vision changes that are frequently overlooked in general health guidance. Hormonal shifts alter fluid retention throughout the body, including in the cornea and lens, which can cause prescription fluctuations.

Women who are pregnant should be aware that:

  • Soft contact lens fit and comfort may change during pregnancy due to corneal shape shifts.
  • Vision prescriptions obtained during pregnancy may not remain accurate postpartum.
  • Gestational diabetes carries the same retinal risk as Type 2 diabetes and warrants a dilated fundus exam if blood sugar control is poor.
  • Preeclampsia (pregnancy-related high blood pressure, occurring in approximately 5 to 8% of pregnancies in the U.S.) can cause visual disturbances including blurred vision, flashing lights, and temporary vision loss, which are medical emergencies requiring immediate evaluation.

Pregnant women should not update their glasses or contact lens prescriptions until at least 6 weeks postpartum or until hormone levels have stabilized, to avoid investing in a prescription that will soon change.

Autoimmune Conditions and Eye Health

Several autoimmune conditions significantly affect eye health and require more frequent monitoring than the general population schedule:

  • Rheumatoid arthritis: Associated with dry eye disease (keratoconjunctivitis sicca, a condition where the eyes do not produce enough tears or produce poor-quality tears), episcleritis (inflammation of the tissue covering the white of the eye), and scleritis (deeper inflammation that can threaten vision).
  • Lupus (systemic lupus erythematosus): Can cause retinal vasculitis (inflammation of retinal blood vessels) and hydroxychloroquine (Plaquenil) toxicity. The anti-malarial medication commonly used to treat lupus can deposit in the retina and cause irreversible vision loss. Patients on hydroxychloroquine should receive a baseline eye exam and annual monitoring with OCT and visual field testing.
  • Multiple sclerosis: Can cause optic neuritis (inflammation of the optic nerve causing sudden vision loss and pain with eye movement), which is often the first symptom of MS in many patients.
  • Ankylosing spondylitis and related spondyloarthropathies: Associated with acute anterior uveitis (inflammation of the colored part of the eye), which requires prompt ophthalmological treatment to prevent complications.

People with these conditions should discuss a customized vision monitoring schedule with both their rheumatologist and their eye care provider.

Telehealth and Remote Screening: Emerging Options and Limitations

Telehealth options for vision and hearing evaluation expanded significantly following the COVID-19 pandemic and have become a meaningful component of the U.S. healthcare landscape.

What Telehealth Can Accomplish

  • Symptom triage: Helping patients determine whether their concern requires urgent in-person care or can be managed with a scheduled appointment.
  • Medication management follow-up for patients already diagnosed with stable conditions.
  • Remote retinal photography interpretation: Some platforms allow patients at certified retail pharmacy locations to have retinal photos taken by a technician and reviewed remotely by an ophthalmologist for diabetic retinopathy screening.
  • Online hearing screeners: Validated tools such as the HHIE-S questionnaire (Hearing Handicap Inventory for the Elderly, Screening version) and digit-in-noise tests (smartphone or web-based tests that measure a person’s ability to hear numbers spoken against background noise) can indicate whether a formal evaluation is warranted.

What Telehealth Cannot Replace

Telehealth cannot substitute for an in-person comprehensive exam in the following situations:

  • Any child needing a first or follow-up vision evaluation.
  • Any person with new or changing symptoms (sudden vision changes, eye pain, sudden hearing loss).
  • Glaucoma monitoring requiring intraocular pressure measurement and visual field testing.
  • Contact lens fitting and follow-up.
  • Fitting and programming of prescription hearing aids.
  • Diagnostic audiological testing requiring calibrated equipment in a sound-treated booth.

Sudden sensorineural hearing loss (SSHL), defined as hearing loss of 30 dB or more across 3 consecutive frequencies occurring within 72 hours, is a medical emergency. It requires immediate in-person evaluation and may be treated with oral or intratympanic corticosteroids (steroids injected directly through the eardrum into the middle ear space). Patients experiencing sudden hearing loss in one or both ears should go to an emergency room or contact an ENT immediately, not wait for a telehealth appointment.

When to Seek Care Outside the Scheduled Timetable

The schedules described throughout this article apply to people who are asymptomatic or managing stable known conditions. Certain symptoms require evaluation immediately, regardless of when the last scheduled test occurred.

What to Bring to Your Appointment

Preparing properly for a vision or hearing appointment significantly improves the efficiency and accuracy of the evaluation.

For a Vision Appointment

  • Current glasses and contact lenses (both pairs if you have more than one).
  • Complete list of all medications including eye drops (brand name and dosage).
  • List of any known allergies, particularly to eye drops (tropicamide and phenylephrine are commonly used dilating agents).
  • Family history of glaucoma, macular degeneration, retinal detachment, or cataracts.
  • Most recent vision prescription if available.
  • Sunglasses for after the appointment (pupils remain dilated for 4 to 6 hours after dilation, causing light sensitivity and difficulty with near focus).
  • A driver, if possible, since driving immediately after dilation is not recommended for many patients.

For a Hearing Appointment

  • Complete list of all medications (many drugs are potentially ototoxic).
  • History of noise exposure (occupational, military, recreational).
  • Any previous audiograms or hearing test results.
  • Current hearing aids if worn, including the programming remote or app if applicable.
  • A trusted communication partner if available, who can provide additional history about communication difficulties observed at home.

FAQs

When should a baby have their first hearing test?

All newborns should have a hearing screening before leaving the hospital, ideally within the first 2 days of life and no later than 30 days of age. If the initial screen is not passed, a full diagnostic audiological evaluation must be completed by age 3 months.

Identify the age in years, months, days and minutes given a date of birth with the online age calculator.

When should a baby have their first eye exam?

A basic vision check, including a red reflex test and structural evaluation, occurs at birth as part of the standard newborn examination. The AAP recommends screenings at every well-child visit, with the first formal visual acuity test recommended at age 3.

How often should children get eye exams?

Children should have vision screenings at every well-child visit from infancy through school age, with a comprehensive eye exam at age 3, age 5 or 6, and then every 1 to 2 years through adolescence. Children with diagnosed vision problems should be seen annually or as directed by their eye care provider.

At what age do children need hearing tests at school?

Most U.S. states require school hearing screenings at specific grade levels, typically kindergarten, first, second, third, and fifth grades. These are pure-tone audiometry screenings and are not a substitute for a full diagnostic hearing evaluation if concerns are present.

When should adults start getting regular eye exams?

Adults should establish a baseline comprehensive eye exam by age 18 if one was not completed in adolescence. Healthy adults with no risk factors or symptoms can then follow a schedule of every 2 years through age 39, with increasing frequency beginning at age 40.

How often should adults over 65 get vision and hearing tests?

Adults 65 and older should have a comprehensive dilated eye exam and a full hearing evaluation every year. Annual testing at this age is standard because the risk of cataracts, glaucoma, macular degeneration, and age-related hearing loss rises substantially in this population.

Does Medicare cover eye and hearing exams?

Traditional Medicare Part B does not cover routine vision or hearing exams for most adults. It does cover annual dilated eye exams for people with diabetes and those at high risk for glaucoma. Medicare Advantage plans often include vision and hearing benefits, so plan specifics should be reviewed individually.

What age does hearing loss typically start?

Age-related hearing loss (presbycusis, meaning the gradual decline in hearing ability that occurs as part of normal aging) typically begins in the mid-40s to early 50s but becomes more noticeable and measurable by the mid-60s. Approximately 1 in 3 adults ages 65 to 74 has clinically significant hearing loss.

What is the recommended vision test schedule for someone with diabetes?

People with Type 2 diabetes should have a dilated retinal exam at the time of their diagnosis and then annually after that. People with Type 1 diabetes should begin annual dilated exams within 5 years of diagnosis. More frequent exams may be recommended if diabetic retinopathy is detected.

At what age should you get a baseline eye exam for glaucoma?

The American Academy of Ophthalmology recommends a baseline comprehensive eye exam at age 40 for adults at average risk, which is when early signs of glaucoma and other age-related eye conditions may first appear. Adults with a family history of glaucoma or who are of African American ancestry should begin screenings earlier.

How often should a healthy 50-year-old get a hearing test?

A healthy adult at age 50 with no known hearing problems or significant noise exposure history should have a hearing evaluation every 3 to 5 years. Those with occupational noise exposure, a history of ear infections, or early signs of hearing difficulty should be tested annually.

What hearing test schedule is recommended for someone who uses headphones a lot?

Anyone who regularly uses headphones at high volumes, particularly at settings above 60% of maximum volume for more than 60 minutes per day, faces elevated risk of noise-induced hearing loss and should have a hearing screening annually, regardless of age. This applies especially to teenagers and young adults.

Can a child pass a school vision screening but still have vision problems?

Yes. School screenings primarily measure distance visual acuity and may miss near vision problems, convergence insufficiency, color vision deficits, and early eye disease. A comprehensive exam by a licensed optometrist or ophthalmologist provides a far more complete picture of eye health.

How much does a hearing test cost without insurance?

A full diagnostic audiological evaluation performed by a licensed audiologist in the United States typically costs between $250 and $350 without insurance coverage. Some community health centers, university audiology clinics, and hearing aid retailers offer screenings at reduced cost or at no charge.

What is the earliest age a child can be fitted for glasses?

Children can be fitted for glasses at any age, including infancy, if a refractive error or condition such as amblyopia requires correction. Pediatric ophthalmologists routinely prescribe glasses for children as young as a few months old when early treatment is necessary to support normal visual development.

Is there a free vision test schedule for children in the U.S.?

Yes. Children under 21 enrolled in Medicaid receive vision exams and corrective lenses at no cost through the EPSDT program. Many states also provide school-based vision screenings at no charge, and organizations like the Lions Club and VSP Vision Care operate community programs offering free or low-cost exams.

How do I know if my toddler has a hearing problem?

Warning signs include not startling at loud sounds by 6 months, not turning toward sound sources, not babbling by 9 months, not saying a first word by 12 months, not using two-word phrases by age 2, and frequently asking for repetition or watching faces intensely when being spoken to. Any of these signs should prompt an immediate referral to an audiologist.

What is the difference between a vision screening and a comprehensive eye exam?

A vision screening is a brief pass-or-fail check of basic visual acuity, typically performed by a pediatrician, school nurse, or technician. A comprehensive eye exam is a detailed evaluation performed by an optometrist or ophthalmologist that assesses refractive error, eye health, binocular function, intraocular pressure, and the health of the retina and optic nerve. Screenings identify who needs further evaluation; exams provide the diagnosis.

When should someone get their hearing tested for the first time as an adult?

Adults with no prior hearing evaluation should complete a baseline audiogram no later than their early 30s, or sooner if they have had significant noise exposure, a history of ear infections, or family history of early hearing loss. The baseline audiogram serves as a reference point for detecting future changes accurately.

Do I need a hearing test if I feel like my hearing is fine?

Yes. Hearing loss often develops gradually and without obvious symptoms until it is moderately advanced. A baseline hearing test while hearing is still normal creates a critical reference point. The NIDCD notes that on average, people wait 7 to 10 years after noticing changes before seeking evaluation, a delay that significantly limits intervention effectiveness.

What vision and hearing tests are done during a Medicare wellness visit?

The Medicare Annual Wellness Visit includes a brief vision impairment screen and a basic hearing impairment screen using standardized questions or a validated questionnaire. These are not comprehensive exams. A positive screen should result in a referral for a full clinical examination, which is billed and covered separately based on specific Medicare criteria.

What is sudden sensorineural hearing loss and how quickly should it be treated?

Sudden sensorineural hearing loss (SSHL) is defined as hearing loss of 30 dB or more across 3 consecutive frequencies occurring within 72 hours, typically in one ear. It is a medical emergency. Treatment with oral or injected corticosteroids is most effective when started within 72 hours of onset, making immediate evaluation at an emergency room or ENT office critical.

Are over-the-counter hearing aids as good as prescription hearing aids?

OTC hearing aids introduced in 2022 are appropriate for adults with mild to moderate hearing loss who do not have complicating medical factors. They offer genuine benefit to many users at a fraction of the cost of traditional hearing aids. However, they are self-programmed and lack the customized fitting, advanced sound processing options, and ongoing audiological support that prescription devices and audiologist-led care provide. Adults with moderate to severe loss, asymmetric loss, or complex hearing needs should see an audiologist.

Can vision problems cause headaches or learning difficulties in children?

Yes. Convergence insufficiency (difficulty coordinating both eyes when looking at near objects) is particularly associated with reading-related headaches, eye strain, blurred vision during reading, and avoidance of near tasks that can be misinterpreted as attention or learning problems. Studies show that up to 15% of children may have some form of binocular vision dysfunction affecting reading performance, and many of these children pass standard distance acuity screenings.

What medications can cause hearing loss or vision problems?

A significant number of common medications carry ototoxic or ocular toxicity risk. For hearing, notable examples include cisplatin and other platinum-based chemotherapy agents, aminoglycoside antibiotics (gentamicin, tobramycin), loop diuretics (furosemide), and quinine. For vision, hydroxychloroquine (Plaquenil) can cause retinal toxicity with long-term use, tamoxifen (used in breast cancer treatment) can cause crystalline retinopathy, and oral corticosteroids used long-term raise the risk of cataracts and glaucoma. Patients starting any of these medications should discuss baseline and monitoring testing schedules with their prescribing physician.
