A research team led by Dr. Robert Hess from McGill University and the Research Institute of the McGill University Health Centre (RI-MUHC) has used the popular puzzle video game Tetris in an innovative approach to treat adult amblyopia, commonly known as “lazy eye”. By distributing information between the two eyes in a complementary fashion, the video game trains both eyes to work together, which is counter to previous treatments for the disorder (e.g. patching).
