Amblyopia or "lazy eye" is a condition affecting 2 to 3 percent of the U.S. population and one in every 20 preschoolers. It can cause permanent loss of vision if left untreated. Amblyopia usually affects only one eye resulting in a condition known as monocular vision. Many children don't realize they should be able to see through both eyes. Parents are often completely unaware of any problem with their child's sight.
