I purchased 2 pairs with different magnification. Then popped out and re installed lenses to match my eyes. I use 1x for my left eye distance and 2.5x for my right eye to focus my sight picture, crystal clear.
2 pairs is still way cheaper than having and optometrist create shooting glasses for you. This works for me, depending on your glasses prescription, it may work for you as well.

I have been buying these for several years...different diopters depending on activity. They may be long lasting if you can keep from breaking the temple pieces (I cannot). I just ordered a competitors to see if theirs hold-up better. Please sell replacement temple arms.

I had searched everywhere for a pair of FULL lens magnification safety glasses to use for shooting; but all I could seem to find was the bifocal type - until these turned up in my search. I wear multifocal contacts which are fine for general purposes; but vision will not be perfect and crystal clear at every distance (near, mid-range and far) with those alone - it's the nature of the beast. No one ever said dealing with aging eyes is fun! And trying to wear bifocal glasses for shooting is, for me at least, a nightmare. It just does not work!
What I needed was just enough magnification (in addition to my multifocal contacts) to bring the front sight of my gun into clear focus without blurring the target too much. Enter the +1.0 FULL LENS reading glasses type magnification. Unfortunately they were impossible to find - until these. There are many safety glasses out there with bifocal options, but as far as I know these are the only ones made like readers with full magnifying lenses.
If you shoot and are having the same type of issue, I highly recommend these. Do some experimenting with reading glasses first to determine what strength you need. And FYI, you'll probably want to go slightly lower in strength. I sometimes read small print with +1.25 readers in addition to my contacts; but the +1.0 works better for the "arms' length" distance to the front sight of my handgun. I first tried the +1.5 (they apparently don't make these in +1.25) but those blurred the target too much so I went down to the +1.0 and they were perfect! What a difference it has made! I only wish these glasses came in different colored lenses for shooting in different lighting conditions, but at this price point I'm just happy to be able to see! Other reviewers say the arms on these glasses break easily; so I try to be conscious of that when using them and I'm ordering a couple of extra pairs to keep on hand for that eventuality.

They help my vision for sporting events.

Getting older eyes suck but these really help when welding, carb work etc. Worth the money
