More than a prescription
An eye examination can check how clearly you see and whether a glasses or contact lens prescription may help. A comprehensive visit also gives your optometrist an opportunity to evaluate eye health, discuss symptoms, and consider risk factors from your personal and family history.
Many eye diseases can develop without obvious early symptoms. That is why feeling comfortable and seeing clearly do not always answer every eye-health question.
Why dilation may be recommended
Dilating drops widen the pupil so the doctor can see more of the retina and optic nerve. The National Eye Institute notes that dilation can help check for conditions including diabetic retinopathy, glaucoma, and age-related macular degeneration.
Not every visit is identical. Your optometrist will decide which examination elements are appropriate based on your age, symptoms, health history, and previous findings.
Make the visit useful
Bring your current eyewear, a medication list, and any questions about changes you have noticed. Mention headaches, eyestrain, changes in night driving, flashes, floaters, dryness, or a family history of eye disease. Those details help put the test results in context.
