How good are your visual skills? See if you can find the odd one out in this visual quiz.

School-age children and adolescents
Have your child’s vision checked before he or she enters kindergarten. Your child’s doctor can recommend how frequent eye exams should be after that.

Adults
In general, if you are healthy and you have no symptoms of vision problems, the American Academy of Ophthalmology recommends having a complete eye exam at age 40, when some vision changes and eye diseases are likely to start. Based on the results of your screening, your eye doctor can recommend how often you should have future eye exams.

If you’re 60 or older, have your eyes checked every year or two.

Have your eyes checked more often if you:

Wear glasses or contact lenses
Have a family history of eye disease or loss of vision
Have a chronic disease that puts you at greater risk of eye disease, such as diabetes
Take medications that have serious eye side effects
