AmblyoPlay is helping my 8 years old daughter to recover the left eye. She had beed diagnosed with only 20 % visual acuity and now she is a full process of recovering. All games that she is playing in the app are designed to force eyes to work as a team and to recover the one who is behind in terms of visual accuity. There are games for every child or person and it just keeps you focused because it gives you gems and other compensations that you can use to upgrade your game character.
