Amblyopia is commonly treated by wearing an adhesive patch over the non-amblyopic eye for several hours per day, over a period of many months. The purpose is to restrict the use of the good eye while forcing and training the amblyopic eye to work properly. This often gives disappointing results as it is unpopular, prolonged and it can even make the squint worse. As this treatment maybe last several months, little children often feel boring and become less cooperative. To overcome the difficulties, Ping Pang Tetris is a mobile game that functions as a eye testing suite for children. This is mainly on standard mobile devices and therefore is accessible at low cost at anywhere anytime The main technical initiative is to separate two views from both eyes in order to allow different training to them. The separated views can lead to separated vision on foregrounds and backgrounds. The separation of the foregrounds and backgrounds into two different views will allow the training of the coordination between two eyes, This will force the patient to use the weak eye on the foreground objects, while looking at the background (e.g. environment) using the healthy eye.
