My daughter went for a checkup and we were told she had a lazy eye. The doctor's recommendation was to wear the glasses and see if it did not improve. A few hours on the web told me that was not acceptable, that the eye needed to be patched, or perhaps drops used that would blur the good eye to make the lazy eye work. At seven years old, there is not a lot of time to fix the eye. We took her to a pediatric opthamologist, where we found out the prescription was completely WRONG!! We had been making her wear those glasses, and her vision WITH them was 2250. I EMPHATICALLY DO NOT RECOMMEND THESE PEOPLE.
