My son (9yrs) has Duane Syndrome and has struggled with tracking issues and double vision since birth. Amblyoplay has been a wonderful tool for us. We have been doing variations of vision therapy since he was 5 and have seen improvements, but this system allows my son more independence with great results. Also, he really enjoys it! Previous digital therapy programs we used were effective, but boring. This is fun! No more fights to get him to do it! Hurray! And the fact that his therapist can monitor his progress and make adjustments as we go is amazing. The cost compared to regular office visits or some of the other technologies is very reasonable too. Definitely a worthwhile program.
