RE: blurry vision
Can't say what it's going to do for you Frank but I don't have an issue with mine. Being that close to your eye with your focus being so far away from it I'd think that all peeps have a "blurred edge" to them just like a ghost ring sight on a rifle, the problem is when what you're looking at through them is blurred. If that's the case then either the peep is out of alignment (rotational or up/down) or you need a clarifier lens in the peep (for target/scope applications).
