20/20 vision is only part of how our eyes function. Many people can have good acuity and have poor visual skills which significantly impact the way they see. Due increased near point work in classrooms, many children fatigue quickly and underlying vision issues become more prominent. Blurry vision, double vision, losing one’s place, and decreased reading comprehension are just a few symptoms a child may experience during classroom activities.
Our two eyes see two separate images. The brain overlaps the images to create a single and clear picture of the world around us. If the eyes and the brain are not working together efficiently, the picture can become distorted, blurry, or even double. Conditions that can be treated with vision therapy include convergence insufficiency, accommodative insufficiency, strabismus, and issues with visual information processing. Binocular dysfunction impacts one’s ability to learn efficiently and effectively.
Binocular vision issues may not always be obvious. Many kinds of vision problems reveal themselves most easily in behavior, posture and attitude. Many signs of A.D.D. or A.D.H.D. are similar to those for vision deficits. These signs are usually associated most closely with long periods of visual work done at less than arm’s length from a person’s eyes. Many vision problems can be easily identified through observation alone and often checklists are helpful. If you mark more than a few signs, there is good reason to suspect a vision problem.
