What Causes Lazy Eye?
3. Refractive Errors
The second type is the refractive amblyopia. If there are unequal refractive errors in both eyes, amblyopia occurs. For example, if one has farsightedness and the other does not, it may lead to amblyopia. The brain ignores the visual input of the more uncorrected refractive error and depends on the other, less uncorrected eye.
Another possible cause of lazy eye is deprivation amblyopia in which something such as a congenital cataract is obstructing light from entering the infants eye.
