According to the American Optometric Association (AOA), up to 80% of a child's learning in school is through vision. Also, according to a 2015 statement from the College of Optometrists in Vision Development (COVD),
“More than 5 million children in the U.S. have eye coordination and eye focusing disorders which cause them to continue struggling with reading despite the best interventions....Children don’t know how they are supposed to see, so they rarely complain; they show us they have a problem with their behavior.”
Most people do not realize how many visual skills are necessary for learning. Unfortunately, the emphasis (including school screenings) is mostly on visual acuity. Visual acuity only gives part of the picture. Other skills such as eye teaming, focusing, and visual tracking are not evaluated in school screenings and often go unevaluated. Eye coordination and eye focusing problems can make learning difficult; they can make the words appear blurry, double, or look like they are moving.
The College of Optometrists in Vision Development (COVD) website outlines at least 17 visual skills necessary for learning. Other resources, such as the book "The Hidden Link Between Vision and Learning: Why Millions of Learning-Disabled Children are Misdiagnosed" by Wendy Rosen, outline more. These visual skills include: Eye Movement Control, Eye Teaming, Vergence, Convergence, Divergence, Focus Accommodation, Depth Perception or Depth Awareness, Peripheral Vision, Visual Motor Integration, Visual Spatial Skills, Visual Memory, Visual Form Recognition, Visualization, and near and far visual acuity.

According to the College of Optometrists in Vision Development (COVD), the majority of vision screenings performed in schools and pediatricians’ offices are not designed to test for problems with eye coordination, tracking, or focusing. In fact, vision screenings miss at least 50% of vision problems. In addition, general eye exams often do not thoroughly evaluate all the visual skills required for academic success.
5 Common signs that a vision problem may be interfering with reading and learning are:
In a 2014 statement, the President of the College of Optometrists in Vision Development (COVD), Dr. Ida Chung, stated,
“When a vision problem is at the root of a child’s struggles with learning, it is often very correctable....This is good news for parents and educators. Often years of struggling can be turned around with a program of optometric vision therapy.”
