It is estimated that vision accounts for as much as 80% of the learning process. As grade level increases, so do the demands on a child's visual abilities. As the text size in school books decrease, the amount of time spent reading and studying increases. Class work and homework require strenuous effort on the part of a child's eyes. A vision problem places a hurdle in the way of a student's learning process.
Children should have a comprehensive eye examination before starting school so that an eye doctor can determine if a child's vision system is prepared for reading, writing and other close work. The demands of schoolwork can put stress on a child's visual system resulting in the development of eye problems the child may not have had before. Good vision is more than seeing clearly or having 20/20 eyesight. It is also the capacity to comprehend and process what is seen. Basic visual skills include the ability to use both eyes together as a team, move them effectively, and focus both distant and near objects. Without these basic skills a child's ability to achieve his or her true potential in the classroom is effected. Remember this: Children don't often realize the strain their eyes are under, making it difficult to recognize and seek help for vision concerns. Because their vision is "normal" to them, kids may think everyone sees the way they do. Also, vision can change frequently during the school years, further emphasizing the importance of regular eye and vision care.
