Vision is more than 20/20. Many people have a false security of 20/20 as being the “perfect” vision. In fact, 20/20 visual acuity is only a measurement of how small of letter you can see at 20 feet. It does not give any insight of how your brain perceive what you see. It does not tell us if your eyes are teaming, tracking or focusing together or accurately. And let’s not assume 20/20 visual acuity equals 20/20 acuity at near. The term ” 20/20″ should not be used synonymously with the word “Vision.” Vision is a complex process that involves more than 20 visual skills and over 65% of brain function. Any deficiency in vision can lead to academic and behavioral problems that are greatly overlooked by teachers and professionals.
Learning is a multi-factoral skills that involve vision, eye-hand coordination, auditory process, attention, cognition and more. It is approximated that 65% to 85% of learning is visual. Vision Therapy helps with visual-based learning problems but it does not claim to “cure” learning disability.
