I subscribed to Amblyoplay for my 13 year old son who has a 'lazy' eye & has done since birth. He sees an ophthalmologist regularly and has done eye patching at a young age but no other therapy to date. The subscription process was very easy and our starter pack arrived quickly despite having winged its way all the way from Slovenia to Australia. Set up was also easy with some calibrations required to ensure the program was tailored to my son's specific needs. The program works by way of a number of 'games' which are played whilst the subject wears special glasses. The games are aimed at working each eye separately and in so doing, strengthening them to work together. My son being 13 found the games a little below his maturity level but did persevere and was happy enough. Time-wise, a full session done in one go will take a 45 minute time commitment (2 x 15 mins on games with a 15 min break in between). Understandably, the sessions must be of sufficient length to exercise the eyes and with this, a break is required during the process. It is possible to break the sessions into 1 morning & 1 evening (15 mins each) to get around this. The only issue I have had is getting my son to commit to either the full 45 mins or to come back to a second session in one day as he has lots of homework and other commitments but that is more to do with my son than the program I suspect. I do believe the program makes a difference to his eyes and hope we can find a way to keep him working at it to get the longer term benefits. The organization is also very contactable & professional when you have questions. Recommended.
