Are you truly speaking of lazy eye, or Amblyopia? Amblyopia - sometimes called lazy eye incorrectly, is a condition when (usually) one eye, is not developed properly at birth and the child has blurry vision. It can be helped if caught early enough. Left untreated, it will render the person a lifetime of blurry vision. I was born with Amblyopia and it was unfortunately never treated. Not until I was about nine years old, did teachers at school tell my mother than I couldn't see very well. By then it was too late. I certainly worry about my good eye and just lately have noticed that I don't see very well, even with glasses. I believe true lazy eye, actually refers to another disease of the eye. Can't remember just what though, right now.
