I'm lucky to have a World class uspsa shooter as my optometrist .
Of course I need glasses for every day use, so he recommended mono vision glasses. Right eye for up close and left eye for distances.
I've been told that it's impossible to see clear near/far at the same time with a mono vision setup (that's what they say)? but it works for me and I shoot with both eyes open.
Once a pond of time many moons ago I had a problem shooting high with my shotgun( so being a Brain Surgeon), I cut the stock at the receiver to change the angle bringing the barrel down ( ugly looking gun looks like termites got to it). Now It's my big match SG. I haven't had to do this with any of the others - go figure.
I reserve the right to edit this post when needed.
