Here is a simple yet very effective way to test your eyes for a peep sight without having 1, Take a good clear set of Safety glasses, cover the lenses with black tape, totally blacken them out, cut a tiny peep hole in the tape for your sight eye, Test this with your regular open sights and see if it makes a difference? Get on a bench and put your rifle on a target, Test Back n Forth with and without the modified glasses, Like i said you might be pleasantly surprised
When i cut my right eye years ago I really thought i was gonna go blind in it? I was bed ridden in the dark for a couple of days by Dr orders, When i started getting out and trying to see again I simply couldn’t? Everything was cloudy, I couldn’t see my hand in front of my face? All i could tell was light from dark. At My checkup Dr appointment I expressed my fear that I would never be able to see again in that eye? The Dr looked my eye over closely with a headset magnifying type thing, he said ‘it looks great, healing right up! I’m gonna have you do an eye test’ I looked at him and in a PI$$ED off way and said an eye test??? ‘THIS AINT A JOKE TO ME!! I CANT SEE ANYTHING, I AM BLIND in it!! The eye Dr smiled and handed me a Spoon shaped thing, it had several tiny holes spaced apart in it, he had me close my good eye and hold that spoon shaped thing up to my bad eye and look through it, WOW!!!! I COULD SEE AGAIN!! I could EASILY read the 20/20 eye test! But as quick as i removed that thing i went blind again? Everything was a Hazy, Cloudy mess. Everyday my eyesight got a little better until i peaked out, That happened 28 years ago. Like i said my eyesight in that eye has never been the same. Regular open sights on a rifle are basically a joke to me, But i can shoot a peep sight VERY well, i have shot all the way out to 500 yards!
