I took out the old Smith for some semi-serious 50 ft. offhand target practice. I'm trying to see if my new progressive lenses will make it possible for me to shoot with iron sights. It takes a lot of head tilting to find the sweet spot in the lens. I think my iron sight days are over but I'm not giving up.
I keep adding up the cost of all the scopes I have, I bet that would get me some real nice eye glasses
Not much you can do with astigmatism. The higher the magnification you need the shorter the depth of field. Tape over the lens with a pinhole trick can help. Get some cheap readers and experiment with magnification and aperture (hole size in the blinder) size.
