Well,I know what your saying. I’m just 47, and wear contacts/glasses I hate shooting with glasses on my face. They seem to get in the way and mess things up. The distance is my eye problem. I always tell others that have the same issues, optics’s will let you shoot what you couldn’t see.475 is no problem, its when I get back to 871 its hard enough seeing 30 cal holes 6.5 can't do it anymore with my 60 year old eyes.
