Please go to a pediatric opthamologist. If your child does have a lazy eye it is best to get treatment as quickly as possible, to prevent permament vision loss or problems. Your pediatrician may be able to give you a referal.
My daughter had started showing symptoms of vision problems at three. She was diagnosed with amblyopia and had to get glasses and wear an eye patch a few hours a day for months. The only reason, I knew to look for that eye problem was due to the fact that I had the same problem as a young child. Most parents have no idea that their children has this eye problem because the child's brain will compensate and rely on using the good eye and eventually, the weak eye will get "turned off" by the brain if not treated. I live in the Wylie area and I go to Grapevine to see Dr. George Beauchamp. He is excellent with children, his staff is great and now my daughters vision is corrected. She still needs glasses but no longer has symptoms of amblyopia and no longer needs an eye patch. I know Grapevine is kind of a long drive but it's worth it to get the best vision for your child.
