Bifocals are a sign of aging, I guess, but trying to shoot accurately with them is a struggle. If I look through the lower lens, I can align the sights, but the target is blurry. If I aim through the upper lens, then I can see the target clearly, but the sights blur. Right now, I find that using the upper lens to see the target, and trying to get some equal distance between the spots on the sights and align them works, but without the precision of pre-bifocals time.
Can anyone offer me some advice?
