It looks a lot like the stuff at carrick. I believe that it helps a lot of people but not all.

I used the dynavision (board with push buttons that light up) at the carrick-trained physician's clinic. And I used it at a hospital. Didn't notice anything.

Playing catch with two tennis balls was part of my therapy, among some eye exercises.

I believe the end of the video said it costs 6-9 grand approximately.
