Good evening,
My son Kevin (now almost 6) was diagnosed at 4 yrs old with not only 1 lazy eye, but both turned inward. By the time we noticed it, he had lost almost all sight in one of them. We did the patch for over a year & bifocals on top of that. It was just not helping, so about 4 months ago, we did the corrective surgery for the turning in problem, which also helps with the lazy eye thing. It worked great for one eye & almost fixed the problem in the real bad eye. We are still in glasses, but hopefull that over time this will not be needed. The surgery is kind of hard on them, I mean it's your eyes. It was the hardest thing to make him understand wy he could not rub his eye (stiches and all) when they hurt or itch. All the drops and creams & bleeding was kind of gross, but well worth it in the end.
His eye doctor, Dr. Hand (the best known pediatric eye doctor in Orlando - you can look him up) (whom I would recomend you take your child to)told me that if he starts to complain (Kevin has always been real good about wearing his glasses also) that we should bring him back in. This could mean the lenses need to be changed or really any number of things. So if your normally tolerant child is now not so tolerant. Do not ignore the sings. Just to be sure he is not uncomfortable I would take him back for a check up.
Could you imagine if he is having a hard time seeing with the current set of glasses, how uncomfortable. They would not understand to tell you, I mean Kevin was practically blind and he did not seem to realize that he could not see. So maybe he just does not realize to tell you, but knows the glasses are uncomfortable.
