Dave, I don't use my eyeglasses when using a scope. I adjust the rear ocular to compensate for my farsightedness until the image in the scope is in focus.
The problem is that when walking around while hunting I do have to wear them to be able to see properly and have to take them off before aiming and shooting.
Having only one pair and worrying about loosing them does not help in the concentration department, ;-)
