Mine are totally different. I asked to have the eye doc (actually his assistant) place my try-focal lens on the top and my bi-focal lens in the normal bottom position. In other words, the top lens is for front sight focus and the bottom lens is for reloading magazines. The entire lens is to my normal prescription. They look weird, but for me the design works amazingly well. Think about it, when you aim your handgun you tilt your head slightly downward. That's when the top upside down lens comes into focus on the front sight.
