Amblyopia (“lazy eye”), the most common cause of vision problems among children, occurs when the brain receives a blurred image from one eye and responds by disregarding this weaker eye’s image. The condition is entirely treatable with early intervention with an eye patch over the stronger eye, which forces the brain to recognize the weaker image. First, if there is a refractive error (nearsightedness, farsightedness, or astigmatism), corrective lenses must be prescribed. Although a refractive error that is different in each eye (myopic anisometropia) poses a larger challenge, new research shows that this rare form of amblyopia can be successfully treated by wearing fully corrective glasses for 16 weeks, followed by patching for an additional 16 weeks. Strabismus, a condition in which the eyes do not look at the same place at the same time, may be a cause of amblyopia. Vision consists of much more than just 20/20 eyesight. Vision allows us to obtain meaning and understanding from what we see. Poor vision can affect a child’s ability to learn in school and complete homework.
