When to Call A Doctor

Call your doctor right away if you have a dramatic change in vision or sudden difficulty seeing clearly.

Children should have their first eye exam before they are 6 months old, with a follow-up exam at age 3. Adults older than age 40 should have an eye examination every two years, even if they have no noticeable vision problems.
