Anyone tried these and willing to share the experience?
http://www.eyepalusa.com/ said:The Eye Pal® is a modern adaptation of the century-old peep sight, which most people relate to as a pin hole sight (remember those pin hole camera experiments back in school?). The Eye Pal® enables you to simultaneously see the target, your front and rear sights all in focus. And since its made out of a EyePal® Aperturestatic cling material, it can be easily placed on and off of reading, prescription and safety glasses without marring the surface or leaving any residue. Compact, lightweight and virtually indestructable, the Eye-Pal® is the ultimate addition to any shooters kit.
