Yes, that"s what they were made for - you will need a small corrective lens and a diaphragm to give you sharpness of depth perception, and a blind for the other eye (shooting with 2 eyes open always gives better vision).  They're a bit of a bugger to adjust, but they can be quite effective in helping aging eyes to resolve iron sights.

I ordered a pair back in the 1990's and they work very well. Whenever I have a change in the Rx, I just send Decot the new  Rx and the old glasses, and Decot grinds news lenses and puts them in the frames.

I have worn shooting glasses for 35 + years.
I find them very helpful. The asset in using them is that you are no longer looking thru the edge of your street glasses.  The lens is moved to where you are looking thru the center and getting the most out of your correction. I use a German set called Junkers because I require correction for both eyes.  These are adjusted by bending the frames.  I also use the half blinder on the non shooting eye. you want light entering both eyes. The Champion and Knoblocks have a lens holder mounted on a bar. The lens holder offers vertical adjustment and sliding it on the bar frame offers horizontal adjustment. Generally the nose piece is adjustable for height. If you need correction for both eyes, you will need two lens holders.   I never had trouble adjusting to the Junkers.  They aren't seen very often anymore. The only downside is the lens of shooting glasses like Junkers, Knoblock etc...are small offer minimum protection from pierced primers etc...  You may be required to adjust any of them as you change positions, standing , prone etc..  Suggestions for old eyes, breathe a lot ( to keep oxygen flowing to your eyes), Blink at lot, don't stare at the target ( you will imprint the tgt in your eyes) and shoot within your 6-8 second envelope. Nothing replaces young eyes.
