Lazy eye, amblyopia, is usually treated in children with an eye patch over one eye (to help strengthen the other) or a specially fitted contact lens to block out light in one eye, forcing the other eye to work harder.
But what about for adults? Are we stuck looking like pirates? There may be a much more fun alternative. A recent study on adults used Tetris as a way of improving vision in amblyopes with surprising results. Arrrrrr!
