Kicker..... if it is the PINS that you are having a hard time seeing.... this may be your better bet.... especially if you use a peep anyway?! http://www.backcountrybowhunting.com/reviews/archery/verifier.php

I think the sight lenses "usually" magnifies (a little) everything beyond the lens (target and pins).... but not really helping to bring the pins into "focus" along with your target focus.
I'm not sure what they offer these days on the sight lenses... it may be different now.

Just thought I would throw out another option....

Good luck!
