School-aged Vision: 6 to 18 Years of Age | American Optometric Association

A child needs many abilities to succeed in school. Good vision is a key. It has been estimated that as much as 80% of the learning a child does occurs through his or her eyes. Reading, writing, chalkboard work, and using computers are among the visual tasks students perform daily. A child’s eyes are constantly in use in the classroom and at play. When his or her vision is not functioning properly, education and participation in sports can suffer.
