I just happen to be an Optician, however I have a passion for Hunting and shooting.
So many times, there are those of us, that try to shoot with our regular glasses and it just does not cut it- what I have been successful in making is an inverted bifocal Set for the distance between your cheek and your front sight, this bifocal is upside down, on the top of your shooting eye- I leave the other eye alone for your regular prescription- This way you can then See distance and see your front sight! All that I am doing is tricking your brain and allowing it to see two different focal lengths at the same time.
Once we reach 40 plus years old, our eyes because to loose the elasticity that allows us to focus on more than one focal length at a time- I just figured out a way to trick your brain and let it focus on the target and the front sight.
People ask " Why do you put the lens at the top?"
Well this is to Help us to return to proper shooting form- leaning into the recoil, looking straight down the barrel and having much quicker target acquisition! 2nd and 3rd shots come much faster. Too many of us older shooters, start lifting our Chin up and we are leaning back- actually throwing ourselves out of balance and making it extremely difficult for the follow up shots.
The inverted system allows for normal movement around a IDPA Course, or any combat/self defense course- Some of my shooter describe wearing the inverted lens, is like wearing a basball cap pulled down tight, but you get used to it being there- however, when you drop your chin, maybe 1/4 inch, you are now looking through the top bifocal for almost immediate target acquisition- If you can see it you can hit it, if you cant see it you will never hit it-
The rest of the formula is figuring out what bifocal power you need- is it the same power your have on your normal glasses? NO! your normal glasses are set at near 15 inch focal length, and ie if your shooting and Xd 40 and your about 6 ft tall, the distance between your front sight and your cheek - st your dominant eye- is going to be about 24-25 inches, so you will need a weaker sticker to move your focal length out to the proper distance..
Sorry for the Optical theory here- regretably I had two cups of coffee today- and most folks around here, keep telling me, I sure am wound up!
If anybody would need to ask any questions, If you could have this information with you, it sure would help
Your current prescription
Your pupil distance- The metric distance between your eyes- please get this from the last people that made glasses for you- most of the time it is not on your prescription
Your height
Your weight- some get annoyed by this question- A frame that will fit someone 5 foot tall and weighs 100 pounds, will not fit someone 6 foot 11 inches tall and weighs 375 pounds
The distance between your cheek right under your glasses out to your front sight- on the different lenght guns-
Please know this, a lot of current normal glasses are not designed for shooting and a lot of sports frames are not designed for shooting safety-
when your aiming proper form- you should be looking at lens- not the frame all lens- something that gives you good peripheral vision-

I hope I haven't gone over board, but we need to keep shooters shooting and stop the longtime shooters from quiting.
