Eye exams aren't just about updating a glasses prescription — several serious conditions, including glaucoma, have essentially no symptoms until real damage is already done, which is exactly why the interval matters even when vision feels fine.
Diabetes, a family history of glaucoma or other eye disease, and wearing corrective lenses all typically move the recommendation to annual exams regardless of age — diabetes and family history because of disease risk, and corrective lens wearers because prescriptions drift over time even without obvious symptoms.
Glaucoma in particular is sometimes called the "silent thief of sight" because peripheral vision loss can progress for years before it's noticeable — by the time someone notices a vision problem themselves, meaningful and irreversible damage has often already occurred. Regular exams are the only reliable way to catch it while it's still manageable.
Yes — a comprehensive eye exam checks for conditions like glaucoma and early macular degeneration that typically have no noticeable symptoms until real damage has already occurred. Good vision isn't the same as healthy eyes.
Diabetes can cause diabetic retinopathy, damage to the blood vessels in the retina, which often has no symptoms in its early, most treatable stage. Annual dilated exams are the standard way to catch it early, regardless of how well blood sugar is otherwise managed.
Yes — pediatric eye exams use age-appropriate methods (like following objects or picture-based charts) rather than a standard letter chart, and catching issues like lazy eye or misalignment early is significantly more treatable than catching them later.
A vision screening (like the ones sometimes done at school or a driver's license renewal) checks basic visual acuity, but a comprehensive dilated exam checks the actual health of the eye — including the retina and optic nerve — which a simple screening doesn't cover.
Yes — if vision changes noticeably (new headaches, squinting, blurred distance or close-up vision) before your next scheduled exam, it's worth going in early rather than waiting out the calendar interval.
