RE: wearing eye glasses
My vison isn't all that bad. I wear glasses when I sit at the computer.....but I'm not restricted to them to drive. I shoot a verifier lens with my 3D setup, but I don't use the verifier OR glasses when I hunt. I simply switch to a larger peep and I have no issues, that way. I also likely get the added benefit of being able to shoot in lower light, this way.
I wish you luck.
