Most adults should get a comprehensive eye exam at least every two years, with annual exams becoming important after age 65 or if you have risk factors like diabetes. Children need their first screening before they turn one, with regular checks continuing through school age. The exact schedule depends on your age, health, and whether you already wear corrective lenses.
Infants and Young Children
Eye screening starts earlier than most parents realize. A doctor should check a newborn’s eyes shortly after birth to confirm basic indicators of eye health. A second screening happens between 6 and 12 months of age, typically during a routine well-child visit. Between ages 1 and 3, your child’s eyes are checked again for healthy development.
The critical window comes between ages 3 and 5, when a child’s vision and eye alignment should be formally tested. The U.S. Preventive Services Task Force specifically recommends at least one vision screening during this period to detect amblyopia (sometimes called “lazy eye”) or risk factors for it. Catching alignment and focus problems at this age matters because the visual system is still developing, and treatment is far more effective in young children than it is later.
School-Age Kids and Teens
The American Optometric Association recommends a comprehensive eye exam before first grade, then annually from ages 6 through 17. That frequency surprises some parents, but children’s vision can change quickly during growth spurts, and undiagnosed vision problems are a common, overlooked cause of difficulty in school. A child who can’t see the board clearly or whose eyes fatigue quickly while reading may not know anything is wrong because they have no frame of reference for “normal” vision.
Kids considered at-risk, whether due to family history of eye disease, premature birth, or developmental delays, should follow whatever schedule their eye doctor recommends, which may be more frequent than once a year.
Adults Under 40
If you’re a healthy adult in your 20s or 30s with no vision complaints, an eye exam every two years is a reasonable baseline. If you wear glasses or contacts, most providers will want to see you annually to update your prescription and check for any changes to your eye health.
Even without noticeable symptoms, a comprehensive exam can pick up early signs of conditions you wouldn’t feel yet. Glaucoma, for example, causes no pain and no vision changes in its early stages but is detectable during a routine check. Young adults with a family history of glaucoma, high myopia (strong nearsightedness), or a history of eye injury should lean toward yearly exams rather than every other year.
Adults 40 to 64
Around age 40, the lens inside your eye starts losing flexibility. This is when many people first notice they need to hold a menu at arm’s length to read it. It’s a normal change called presbyopia, and it’s also a good prompt to establish a regular exam schedule if you haven’t already. Every one to two years is typical for this age range, depending on your overall health and whether you have any emerging risk factors.
This is also the period when conditions like glaucoma, cataracts, and macular degeneration can start developing silently. Your eye doctor will begin paying closer attention to your eye pressure, the health of your optic nerve, and the condition of your retina during routine visits.
Adults Over 65
The American Academy of Ophthalmology recommends a complete eye exam every one to two years after age 65. At each visit, your doctor screens for the four major age-related eye diseases: macular degeneration, diabetic retinopathy, glaucoma, and cataracts. All four can cause irreversible vision loss if they progress unchecked, but all four are treatable or manageable when caught early.
About 4 in 10 U.S. adults are considered high risk for vision loss, according to CDC data, and being 65 or older is one of the primary risk categories. If you’re in this age group, annual exams are the safer choice over biennial ones, particularly if you have other health conditions.
Diabetes Changes the Schedule
Diabetes is the single biggest reason to increase your exam frequency regardless of age. High blood sugar damages the small blood vessels in the retina, and this damage can progress without any symptoms until vision loss has already occurred.
The guidelines are specific: if you have type 1 diabetes, annual retinal screenings should begin five years after diagnosis. If you have type 2 diabetes, you need a screening at the time of diagnosis and at least once a year after that. The CDC emphasizes that annual eye exams are one of the most important preventive practices for people with diabetes, because early detection of retinal damage can prevent irreversible loss.
Other Reasons to Go More Often
Several factors beyond diabetes can move you into a more frequent schedule:
- Family history of glaucoma or macular degeneration. Both have strong genetic components, and earlier, more frequent monitoring helps catch them before damage accumulates.
- High myopia. Severely nearsighted eyes have a higher risk of retinal detachment, glaucoma, and early cataracts.
- Previous eye surgery. If you’ve had LASIK or another refractive procedure, the American Optometric Association recommends an exam every one to two years to monitor overall eye health, even if your vision feels perfect.
- Certain medications. Some drugs, particularly corticosteroids and certain autoimmune treatments, can affect eye pressure or lens clarity over time.
- High blood pressure. Chronic hypertension can damage retinal blood vessels in a pattern similar to diabetes.
What Happens During a Comprehensive Exam
A comprehensive eye exam is more than reading letters off a chart. Your provider will test how sharply you see at various distances and check whether your eyes are properly aligned and working together. They’ll also look at how your pupils respond to light and assess your peripheral vision.
The part most people remember is dilation, where drops widen your pupils so the doctor can examine the retina, optic nerve, and blood vessels at the back of your eye. This is the only reliable way to spot early signs of conditions like macular degeneration or diabetic retinopathy. Your vision will be blurry and light-sensitive for a few hours afterward, so bringing sunglasses and arranging a ride home is practical.
Eye pressure measurement is another standard component. Elevated pressure is the primary risk factor for glaucoma, and tracking it over time gives your doctor a useful baseline. The test itself takes seconds and involves either a brief puff of air or a gentle touch to the surface of your numbed eye.
Quick Reference by Age
- Birth to 2 years: Screening at birth, then between 6 and 12 months
- 3 to 5 years: At least one vision screening
- 6 to 17 years: Before first grade, then annually
- 18 to 39: Every 1 to 2 years (annually if you wear corrective lenses or have risk factors)
- 40 to 64: Every 1 to 2 years
- 65 and older: Every 1 to 2 years, with annual preferred
- Diabetes (any age): Annually, starting at diagnosis for type 2 or five years after diagnosis for type 1
