Generally speaking, medical experts specializing in the treatment of amblyopia agree that treatment needs to begin the moment the condition is detected. There are several key reasons for this position.
First, as time goes on a lazy eye can start to lose its vision; eventually, it may go completely blind. It can be very difficult to reverse course once this stage has been reached. Second, in time the eye may lose its depth perception, thereby affecting the overall vision of the patient. Finally, should the healthy eye become damaged for whatever reason, the lazy eye will be incapable of providing balance and compensating for vision loss.
