I had cataract surgery (replacement lens) a few years ago. I was nearsighted (well over 20/400), so they said that they had to do the other eye too, because there was no way that I would be able to see properly with only one eye fixed.
The surgeries went well, and my eyesight is the same as it was with glasses, 20/25. Both eyes were covered by Medicare. I find that I can shoot long guns with open, peep, and tang sights. I can shoot pistols with notch/blade and notch/white dot sights. I focus on the front sight, the target, and the rear sight, in that order. If the rear sight is a peep, I hardly notice it there. If the rear sight is a notch, it is a little fuzzy, but clear enough. The front sight and target are usually pretty well in focus.
I still wear glasses, for three reasons: I have worn them since the second grade. They have saved an eye at least three times in my lifetime. With progressive lenses, I can focus at any distance with the tilt of my head.
After the surgery, I discovered that my arms are too short. I have to wear cheaters to read if I am not wearing my progressive lens glasses. I also use a cheater lens in my welding hoods. I use the cheaters, a magnified lamp, or magnifying headgear for detail work. I used to just take off my glasses for detail work!
OP, you should search the net for "merit optical attachment"' and see why it works. Then you could experiment with various size holes punched in black electrical tape attached to shooting glasses to determine what size hole works best for you. This is a cheap and easy way to determine if this would work for you.
On the Garand, it should be possible to buy or modify the peep part of the rear sight to a larger diameter hole. I wouldn't modify my original part, but the aperture units are available on Ebay and elsewhere.
