I have a right lazy eye and when they discovered it, it was to late to patch it up. I was to old. I believe when you are older then eight, it doesn't help anymore. I don't have squinting eyes so my parents and the doctor didn't noticed it.
There are a lot worse things in life, so I am not complaining. Indeed having a good time while shooting is the most important. The fun thing is, that I can outshout practically everybody (if not everybody) with a pistol at our shooting club. Yes, I know that sounds a little arrogant
I can also give a very long list of things that I am not good at, so this keeps it a little in balance
