I’m in my early 50s and wear progressive bifocals (with a further correction for astigmatism). To make matters worse, my dominant eye is my weaker eye. After a year-plus hiatus from shooting a few years ago, I came to realize that with my glasses on, the bumpy thing on the front of the gun was more like a smudge. Ouch.
More recently, as I observe my own performance, I notice this is only a real problem on indoor ranges - no matter how brightly lit. Outdoors, it appears that my pupils contract enough to give me a sharp front sight focus. Indoors or out, a bright orange front sight (Ameriglo CAP or homemade equivalent) helps.
My solution so far has been to wear a set of non-prescription shooting glasses when I shoot indoors; apparently, my uncorrected vision focuses perfectly at front sight distance. (One downside is that with a red dot sight on a carbine or shotgun, I get a lot of bloom.) I worry that this solution, while it helps with pure marksmanship, may cause problems in a self-defense situation where I’m wearing my street glasses - “Wait, where’s that sight I could see at the range the other day?!”
What solutions have any of you come up with?
