When we first started Amblyoplay I was very skeptical. The glasses look just like 3D glasses that you get to watch a 3D movie except with a sturdier wooden frame. The lenses even pop out sometimes and we have to push them back in. However, my son has been using the game for a year now and his vision has greatly improved! We went to his yearly eye checkup last month and his right eye WAS lazy with vision of 20/150 while his left eye was 20/40 and at his appointment his left eye was a perfect 20/20 and his right eye was 20/80! and no longer considered lazy! We had done nothing to improve his vision except for Amblyoplay. Sometimes after he plays, his right eye is very red so it’s really making it work hard! I am most thankful for the game in that he trains the eyes to work together. His right eye was so much further behind that the left eye was becoming really dominant. We were afraid that the vision in his right eye would get worse and worse and could possibly even be “turned off” and not used at all by his brain. I will definitely be running our subscription for another year.
