I had a lazy eye as a child, wore glasses, and even for a while a patch over it. Now, I have perfect vision (I mean, both eyes together compensate for the weakness of the one individually) and no longer wear glasses.
I had it and glasses cured it.I know two people one wears a patch on the good eye to strengthen the weak eye a toddler and I know someone that had it really bad they had a surgery to correct it at 14 the girl is 26 and has beautiful eyes.
then....i would notice!
