Amblyopia, which affects approximately two to three of every 100 U.S. children, is the most common cause of childhood visual impairment. Often referred to as “lazy eye,” this developmental disorder involves reduced visual acuity in one eye because the brain is favoring the other eye. To address the problem, amblyopic children usually wear a patch over the stronger eye for several months, forcing the weaker eye to become stronger. Now, research shows that wearing 3-D glasses and watching “dichoptic” movies (which present different and separate images to each eye) helped children with amblyopia overcome their vision problem more quickly. After watching three dichoptic movies weekly for two weeks, all the children with amblyopia showed a significant improvement in visual acuity.
P.S. Amblyopia may be caused by a large amount of refractive error (nearsightedness, farsightedness, or astigmatism) between the child’s eyes; misaligned eyes (strabismic amblyopia); or cataract in one eye.
