You can try a Peep Verifier lens at different powers. The lens is located with the peep site.
What i did is purchase a low powered pair of reading glasses at 1/4 power which I ordered on line for 21$. Solved the blurring pins issue. The target is lightly blurred. May not work for all eyes.
I also just switched to a one pin sight with a green pin. The green shows up so much better, and no multi pin issues.
