Probably been beat to death but what iron sights are the best for a traditional flinter for a set of aging eyes? At 57, still not bad but I can see the subscription moving a bit. I don't use glasses as much as possible and I run tri-progressives. I thought to get a distance only pair but where does that leave the sights? I think I'm still better with the naked eye but, what have y'all been doing to combat this BS?
