This afternoon an old friend of mine, who I knew to be an excellent shot in the Marine Corps, told me he had problems with sighting now that he wore glasses. I think that is a common complaint. The goal is a crystal clear front sight with a blurred rear sight and target for marksmanship. If you can’t do that with your eye glasses, try a couple pairs of reading glasses at different magnifications. You can buy them in drug stores or dollar stores. You may otherwise need a “shooter’s prescription” for eye glasses . I have noticed that an adjustment period with any type of glasses helps with sighting. Tell your eye doctor what you need to accomplish. Be patient, a lot of shooters with bad eye sight are able to sight very well.
