Oh, not to blow my own trumpet, but I am one of the lucky guys who were born with 40/20 view, or whatever is called when I can see x2 better than the average. So, by the time I lose 50% of it, I will be as any average Joe. Then I will need glasses.
Getting close to 50, still good for now.
That is amazing - I heard that originally, the Australian aboriginals had something lie 6x better vision (or something like that) than Europeans. They would complain about their eyesight, and no one believed they had a problem because it was 20/20.
Yeah, I am a mutant, got also something called crepuscular vision, I can almost see in the dark, not when it is pitch black, but only when is a bit of light around, close to the cats, but not quite. Some strange genes from the maternal side, going only to males, grandpa got that also.
Actually 2x is quite often seen, like 1 in 20k if I remember right, the best is x10, called also eagle vision, only one in a few million, some Finnish sniper had that, for what I know. Just imagine!
