I'll go in a slightly different direction here as you've gotten some good responses. I found my eyeglasses made it very hard to get a good seal on my muffs and I was constantly fiddling with them to get things quieter. Here's what I did. I bought some handball eyewear like this.(There are a bunch of different kinds but the most important thing is to get them with a strap and the lenses are flat.) https://www.amazon.com/Unique-Sports-Eyeguards-Prescription-lenses/dp/B001VYT1HW/ref=sr_1_52 Then I had some lenses made with ANSI Z87.1 protection PLUS bi focals as I have astigmatism and bad eyesight. The strap on the eyewear gives me a good seal and the bifocals allow me to focus on the sights and the target. The lenses were not cheap but better than everything being out of focus.
