when i was a child, i was right eye dominant and my left eye squinted. they put a pirate sticker on my right eye, so i took over the left eye, it stopped squinting and it became stronger in terms of dioptries. (i had glasses as well)
when they removed the sticker, i continued to use the stronger left eye for practical means. i wonder if this has messed me up. you know, how left handed people claim to be messed up through being forced to live right handed.
