Me too, I look at one site pin and it looked like 3 pins really close together. Last year at Christmas
my loving wife spent $60 at Neil's pro shop and bought me a clarifier peep site. It is a metal peep which is threaded on the inside to accept a screw-in insert which come in different strength lenses. I only needed the weakest lens, for now. The site pins are very sharp and clear now, the target is slightly fuzzy. You really need to go to a pro shop to buy one, as you need to try the different lenses. I did get by for a couple years by enlarging the peep hole, but I'm past that point now...
good luck, keep shootin' Tom
