I had my optometrist make me a set for shooting, I call them my Mr Magoo glasses. No transition same grind over whole surface. But they were actually a pain to use as when wearing them I could not write in my log books. But I could darn sure see front sight post!
Have you ever tried a Merit disc or what I used for handgun sihloutte shooting was a piece of tape with a 3/32 hole. Makes rear sight, front sight, and target on the same plane like a camera lens, Works fantastic.
