Is it normal that I can make my vision seem blurry?
I mean, I have the ability to "distort" my vision and make it blurry, simultaneously, doubling objects (I.e seeing two of whatever object(s) is there). I had the ability since I was a child and I've been wondering ever since if it's.. you know, normal. Is it possible that it's just genes (A Discontinous Variation-thing)?
