Also known as “lazy eye.” Amblyopia occurs at a young age from disuse when an eye doesn’t see well. A child’s visual nervous system is still developing until age seven. If during this developmental period, one eye has poorer vision, the “brain wiring” for that eye does not form as strongly as the better eye. This can occur because of early nearsightedness or early farsightedness or from other visual problems such as congenital cataract. This imbalance can also occur if the eyes are in poor alignment (like being cross-eyed). If detected early, amblyopia can be reversed. This is typically accomplished with glasses and patching therapy – by patching the “good eye” closed, this forces the lazy eye to “work” and reform its wiring. There is no way to fix a lazy eye in adulthood as the brain wiring has already formed and the amblyopic eye will never see quite as well.
