Besides pool, shooting pistols and rifles is a part of my life and has been for many years. I have trouble seeing well at long distance and and night, but still pass the driving eye sight exam with out glasses. I also don't see the edge of the ball as good as I used to on long shots. I have read more then once that world class hand gun shooters, base ball sluggers, pitchers, catchers and other stand outs in sports have "better then normal" eye sight. I tried shooting with my glasses on, but don't think I need them. But, when I get an eye exam later this year I will be talking to the eye doctor about the possibility of "pool glasses" or contacts. I am very curious as to how good the eye sight is for some of the world class pool players.
