My daughter Elena has been using AmblyoPlay for almost 6 months. Improvement of her eyesight is incredible. She is now 10 years old and was diagnosed with amblyopia when she was 6. With patching for almost 4 hours daily for 4 years, we have not had a remarkable change. With AmblyoPlay after only 5 months, the results are fascinating. We are all excited. And in fact with only 30 minutes of practice a day! I highly recommend it !!! Thanks a lot, AmblyoPlay!
