Big thanks to the OP, I hadn't ever known these existed. I have to wear +2 reading glasses to be able to read menus, receipts, computer screens etc. My distance vision is still good, but reading distance vision has gone downhill starting around 45 years old. My shooting accuracy has been ok, but I decided to try these top focal shooting glasses out. I ordered the top-focal at a 1.25 power, less than I'd normally use for readers. The kit I got came with a set of top-focal lenses for both eyes in clear, amber and smoke, and a set of non-magnified lenses for both eyes in clear, amber and smoke. So far I've just used a clear top-focal on my dominant eye, and a clear non-magnified on the other eye.

The top focal requires tilting my head slightly forward to see out the magnified portion.

Finally got them to the range today. I got used to them very quickly, and my accuracy was greatly improved. I hadn't been the range in the past month, so I was rusty. Shooting at targets at 7, 10 and 20 yards, I shot more accurately than I have in years. I had previously tried a set of straight +1.5 reading safety glasses, but they distorted everything outside reading distance too much, especially for something where I'd be looking/moving around a lot (like at an IDPA). With these, they work just like normal non-magnified shooting glasses for walking around, etc. Then just a slight forward head tilt and I was able to see the sights perfectly. My shot speed improved as well, since I didn't have to move the sights around trying to figure out how centered the front site was.. I don't think I realized just how bad my sight picture was.

Really looking forward to my next IDPA.
