Chris..... I have a couple of match AR's. These have apertures which I can change out depending on light. The smallest aperture is small enough to be useless on a cloudy day. I also have a carbine type AR. I found the M-1 Garand is easier to have a sharp front sight because the sight raduis is longer than the AR's. The fix? Go to an eye Doc and explain the problem with the front sight. Target can be fuzzy, front post can not. I have a shooting buddy who wears contacts. He was able to get a script for a 1/2 diopter less power for his shooting eye. I wear glasses and have a scrpt for a 1/4 diopter less power for my shooting eye lens. This works for near sighted people but the idea works for both one way or another for far sighted. OK now you know I have two pairs of glasses......one for livin' the other for shootin'.
