How and where do I apply the EyePal® pinhole on my glasses?

At the gun shows people ask “How do I know where to place the EyePal on my glasses?” I have air rifles and bows there to demonstrate where the EyePal is placed on either their prescription lenses, or my safety glasses (which I also sell). EyePal is located on the glasses in the line of sight, where the pupil of the eye is looking through the sights to the target. It’s as simple as that. Some customers use two EyePals, one on each lens to obtain clear “binocular vision”. See the images of EyePal placement at www.eyepalUSA.com.
