If you are near sighted, you are not going to be able to get as clear picture out of a lot of scopes(As stated by somebody earlier,it changes the focal length of the scope). If you move the rifle away from your shoulder, I bet the image will get better. The problem is when you do that the feild of view decreases. This doesn't seem to affect me in the field, only at the target range. The other thing I have found out is that you have to be careful adjusting the focus on some scopes. It can reduce your eye relief and cause the scope to pop you in the eyebrow!!! I had this problem on my Nikon Buckmaster scope. I leave it adjusted for my naked eye sight and I don't have a problem. When I am at the range I don't use my perscription glasses. As I said before, I don't seem to notice it as much when I am hunting. I do use my perscription glasses or contacts when I hunt. If I don't wear them, I can't pick on movement as well.
