Children should have their first eye exam at about age two, although it's never too early to test a child's vision and eye health. Comprehensive eye exams are essential in the diagnosis and treatment of vision problems, injury and disease.

Early detection allows for treatment to begin before the child experiences difficulty in school due to poor vision, or before any permanent damage has been done to the eye(s). Exams test visual acuity, eye tracking, and focusing skills, and detect problems such as near and far-sightedness, amblyopia, crossed eyes, dyslexia, and color blindness.
