How many others are there like me, have to use trifocals. Do you use them to shoot or your top prescription. I've learned to shoot using the top prescription making the sites blurry, and qualified with a 98% and 100% that way. Today I was practicing draw and dry fire with the trifocals and I may need to rethink my habits. I know most may say do what's best for you, but I'd like to hear what other Grandpa's have found more comfortable for them LOL.
