The title kind of says it all. I cannot get the front sight in focus without my glasses, which I do not wear except for reading and computer distances. I would be unlikely to have them on in a SD situation. One of my instructors had a red front sight, non-night sight, I believe, that I could pick up pretty well. Are there night sights, of whatever color, that would, in addition to being night sights, also make it easy for older eyes to pickup the front sight in daylight?
