I still have my Single Prescription Glasses, and I shoot reasonably well with them, I may hang on to them for shooting. It will be a while till my glasses are ready, they are safety lenses. But Im concerned about it.
I just hope the Distance setting has not changed much since my last prescription. I love my Iron Sighted C&R Rifles. The only Bright Side I can see is that I may have an Excuse to give my Wife when I start my Sniper Rifle Collection.
