Reading requires very accurate saccades, which are fixations from one spot to another. Children who have poor eye movements are easily distracted and lose their place.
Once information is brought into the eyes, it must be sent back to the brain for appropriate processing. The information must be utilized and integrated with the sensory and motor areas of the brain. Defects in the perceptual (interpretation of visual system) and motor (the integration with output, e.g., hand-eye coordination) may interfere with the reading process. Perceptual motor skills are key in the early acquisition of reading skills. A deficit is important to identify very early on-- i.e., five to seven years of age. Remediation of the skills at a later date, such as age 12, will be less effective for reading. Thus, early identification and treatment is essential. It is evident that there is more to good vision than 20/20.
