"An estimated five percent of school-age children suffer from an eye disorder called convergence insufficiency, or CI," Christian said. "People with the disorder, which is treatable, have difficulty seeing things at close range."People who have CI will avoid reading, because it gives them a headache. They also have poor reading comprehension. Because their vision is hampered, school kids find it hard to concentrate in class, and are likely to be misdiagnosed with ADD or ADHD.
