I just posted this on another shooting glasses thread:-

"If you have the final prescription for your shooting lens, this outfit give excellent and economical service: https://www.reglaze-glasses-direct.com/

If you only have your prescription for normal spectacles, the lens you need will be somewhere between the "far" and "near" sphere value (Cylinder and axis remain the same).

Make a mock-up of your pistol (length of wood with a "foresight" that you can hold at the required distance) and check the sphere value you need from a rack of ready readers in a local store. Order two lenses, one at this value and another either + or - 0.5 diopter, but with your correct cylinder and axis. At £15 for two lenses you have little to lose and the chances are that one will be spot on. "
