Forget just where, but I said I was going to see my optometrist about a “special pair” of shooting glasses. Never did the follow-up for the brotherhood, so here goes. I had my appointment and we spoke about the pros and cons. This is regarding using iron/open or peep sights. My optometrist is a Marine, and knew exactly what I was after, we spoke at length on this matter. Let me get the “cons” out of the way first.
They would be almost specific to the firearm, a pair ground for my M1 Carbine would not work with the 03 A3. The rub is distance from dominant eye to the front sight post/blade. A pair would work for two or more rifles of near length, within a 3" range for me. (21" to 24" barrel)
Not suitable for anything else other than shooting, would need to change glasses to walk down and re-set target.
As the VA issues one pair every two years, is my current prescription going to make it for another two?
As for the pros…
The sight picture would be improved, i.e., the front sight post/blade would be in sharper focus. That said, it also presents another con. The target may get fuzzier or distorted.
Being far sighted, my likelihood of the target getting fuzzy is reduced.
So from there we went ahead and did the exam, my Rx changed slightly. We decided, for me, the best option was to just get new glasses, forget about a special pair until such time as my Rx is stable.
For marksmen of a certain age, I recommend you have this conversation with your optometrist next visit.
