This game is so much fun! I bought this for my wife and she hasn't stopped using it. The game is so addictive!
There are various exercises which are all aimed at working out your "eyesight age" - dependant on how well you score in the game itself. The games are mixed and varied. You have to do well to unlock other features within the game - hence why this game is so addictive. I would disagree with other reviewers who say the games are repetitive.
There is an excercise where you can rest your eyes - and this bit is boring!
Not only is it suitable for children , but everyone can take part, and you do feel as if you are training your eyes - albeit I am not convinced it actually does.
