If you have a prescription for distance in your glasses, ask your eye Dr for a +.75 lens in front of your current glasses. My Dr. let me bring in a firearm to the office. I was shooting rifle at the time and got some interesting looks from people in the waiting room. The AR and pistol are about the same focal distance. We did the good, better, best with him adding those lens in front of my eye while I was aiming my firearm. You need to tweak your distance prescription so you can see the front sight, too much and the target is a total blurr, too little (what you have now) and you can't see the front sight. You need a controlled blurr. For most people a +.75 to their current distance prescription works. I had another right lens made for an old set of glasses and switch between the two sets I have, one for irons and one for dots ( my regular street glasses). Good luck. Ask your Dr. if you can bring in a firearm.
