I have macular degeneration for 6 years. It was very difficult to read at the beginning and after a while, I was not able to read at all for the last 1-2 years. I started this application with my ophthalmologist’s advice. I could only read words with 3 letters while watching TV or I had to move my head up and down or to the sides to be able to read the whole word. Now I can read the whole word without moving my head. I was not able to read a newspaper for 1 year, and now I can read everything easily except for very little letters. The company was very responsive and always ready to help. I deleted the application by mistake and they re-installed it right away. I am very happy with the result and the service.
