It's the question every patient asks, and the answer most people get isn't quite right. The honest answer depends on your age, your risk factors, and what your last exam showed. Here's the actual framework eye doctors use.
The general adult guideline
For healthy adults with no symptoms, no family history of eye disease, and no contact lens wear, the American Optometric Association recommends a comprehensive eye exam every two years from age 18 through 64. Once you hit 65, that drops to annually because the rates of cataracts, glaucoma, and macular degeneration climb meaningfully.
Why you might need exams more often
Several common situations call for yearly exams even in adulthood:
Contact lens wearers — yearly. The eye changes with lens wear, and many contact-related issues are caught only on close exam.
Diabetes — yearly dilated exams, regardless of age. Diabetes is the leading cause of new-onset blindness in working-age adults, and the early stages of diabetic retinopathy have no symptoms.
Family history of glaucoma or macular degeneration — yearly after age 40, or as your doctor recommends.
High myopia (roughly −6.00 or more) — yearly. Higher risk of retinal tears, detachment, and macular changes.
History of eye disease or surgery — follow your doctor's specific schedule.
Taking certain medications — drugs like hydroxychloroquine (Plaquenil), prolonged steroids, and tamoxifen require specific monitoring schedules.
Children's eye exams
Children should have their first comprehensive eye exam between 6 and 12 months of age (the InfantSEE program offers this free in most US states), again at age 3, before kindergarten, and every two years through school — yearly if they wear glasses or contacts.
School screenings are not a substitute. They catch a fraction of vision problems and miss most subtle issues that affect learning.
Adults over 65
Yearly, no exceptions. The big three age-related issues — cataracts, glaucoma, and macular degeneration — all rise sharply in this decade. Early detection and treatment of any of them protects vision that's effectively impossible to recover later.
When to skip the wait
Don't wait for your next scheduled appointment if you notice: sudden new floaters or flashes of light, a dark shadow or curtain in your vision, sudden loss or blur of vision, eye pain, halos around lights, double vision, or a red eye that doesn't resolve within a day or two — especially with contact lenses. Any of those can mean something time-sensitive is happening.
The takeaway
Two years between exams for low-risk adults. One year for everyone else. And don't wait when symptoms hit — early evaluation often turns a problem into a non-problem. The exam itself takes less than an hour and a half. Compared to the cost of vision lost from a missed diagnosis, that's a remarkable trade.
