I signed up for 6 months and am almost at the end of that 6 months.
My optometrist is impressed with the visual acuity improvement in my right amblyopic, astigmatic and long-sighted eye. I have gained a whole line on the screening chart!
The games are very much kid-oriented, so adults might find some of them a bit tedious. But then others are great nostalgia – like a version of tetris. I must admit, I wasn’t 100% compliant – I didn’t complete the training every day as life happens. However I still achieved good improvements and am looking into extending my access.
