Well I’ve been reading this thread intently. Now age 65 my eye issues are the same as when I was 21… astigmatisms, in both eyes. My vision on good days is 20-20 bad days guessing 20-30. Front vertical sights appear to me to be bent usually to the left. Same with scopes usually where the crosshairs meet. I figure the sight picture is the same each time so I don’t dwell on it.
The real issue is rifle iron sights I can’t get a clear front sight focus. Would love to find a peep sight but would have better luck finding the “Holly Grail”. The Williams Hawken peep is what I really want to try. Beginning to think of trying to make a peep sight rather than wait.
