Children need eye exams to ensure healthy vision. But less than 22% of preschool children receive vision screening and less than 15% receive an eye exam. Vision screening can reveal a possible vision problem but can’t diagnose it. A comprehensive dilated eye exam is needed to diagnose eye diseases.
Amblyopia (reduced vision because the eye and brain aren’t working together properly) is the most common cause of vision loss in children. It affects two to three out of 100 children. Amblyopia should be treated promptly to help avoid vision loss. The U.S. Preventive Services Task Force recommends vision screening for all children at least once between ages 3 and 5 years to detect amblyopia or risk factors for the disease.
