I like wearing contacts to play Pool in... BUT the smoke is a killer for me. I suppose if I tried to force my eyes to get used to that environment, it would help my situation. My Opthalmologist sufggested taking two extra pairs of contacts & that worked very well. I am doing lots of tedious engineering work on my Pool Training Device... so I can't wear glasses on contacts when drawing on a computer... BUT that project will be over soon.
In the interim, I made myself a very nice pair of shooting glasses, had the lenses coated for ANTI-GLARE, tilted them up 15 degrees & my game shot up. I can play all afternoon at home & all nite now.... By the way, I'm 61 years old.
My vision is 425/20 in both eyes for infinity. My Pool shooting prescription is a bit less than my infinity prescription, because I'm fitted for perfect vision at 10 feet.
NOTE: remember this important info. There is only a nickel size area in the lens to peer thru, before refraction causes you to see something that really isn't there. You have to face the shot head on.
By tilting the lenses out, that gave me a perpendicular view of the balls... no more oval balls in my view!
Hope this helps.... email me if you'd like to see my modified glasses.... cb
