My distance vision is excellent, with just slight correction needed, but I need quite strong reading glasses. If you're like me, you've experienced the frustration of fuzzy sights or seeing two or more front sights until I found a solution quite by chance. In the big box chain drug stores like CVS, they have reading glasses for sale in varying strengths. I put on various reading glasses, then held up my fingers like a front and rear sight and they appeared quite clear. I felt I was onto something. Next, I went to my workshop and made what amounts to a sight rib, attaching a front sight to a piece of strip wood and fashioning a rear sight by folding black vinyl electricians' tape against itself and cutting a rear sight notch with a razor. I took this to BJ's and began trying different glasses with my home made sight tool. For obvious reasons, you cannot use either a real or fake gun unless you want to be visited by a swat team. I found that the eyeglasses rated +1.5 gave me the crisp sight picture I haven't seen in 25 years with the target only slightly out of focus. I bought the four eyeglass pack for $20.00. One is now in my night stand, one each for my two range bags and one I carry with me. I've rediscovered shooting. To be sure, I'm fully aware that should the feces interface with the oscillating ventilator, I may not have time to switch glasses but at least I have them if I can. However, I also practice with my bifocals to ensure I remain competent for those quick, come-as-you-are encounters. While +1.5 worked for me, you'll find a large choice of strengths to find what's best for you. You don't need to be too handy to make up the sight rib which you'll need to determine what you need.
