"Lazy eye" is fairly common among kids - it affects an estimated 3 percent of children in the United States. What else do many of these kids have in common? Feeling self-conscious about wearing an eye patch to correct the condition. But a new study's findings may convince these children to wear the patch.
The study found that for children with amblyopia, or a moderate lazy eye, wearing an eye patch for two hours a day is as effective as wearing the patch for six hours a day, which is the standard.
Amblyopia results when the brain favors one eye. This can cause wandering eyes, crossed eyes or a large difference in the visual strength of the two eyes. The weaker eye is forced to improve when a patch is worn over the stronger of the two eyes.
The study's findings appear in a recent issue of the Archives of Ophthalmology.
In the trial, 189 children under age 7 were assigned to wear an eye patch for four months. They were randomly assigned to wear the patch for two or six hours a day, and they were asked to spend an hour per day doing artwork or close-up reading in order to exercise the weaker eye.
The results of the study were surprising: Both groups of children performed identically when asked to read a standard eye chart.
Adherence to the eye-patch schedule is crucial, because in order to prevent visual impairment in adulthood, amblyopia must be treated during childhood.
