Some common signs of visual disorders in children include: difficulty learning to read, poor reading comprehension, avoidance of reading, and trouble recognizing recurring words. A regular eye exam does not check for the conditions that can cause these difficulties, but correction is possible. The earlier the vision problem is discovered, the less your child will struggle; but it is never too late, even for adults. A complete developmental vision evaluation identifies problems with focusing ability, eve movement control, eye teaming and depth perception, visual perception, visual information processing, retained primitive reflexes, and the ability to sustain visual performance adequately to meet the visual demands of the classroom.
