[QUOTE=Adam;203449]Doesn't work with me, I can choose which image to "see".
I just know I have a preference for the right eye.[/QUOTE
We can all choose what item we see when both eyes are open, the magic happens when you close one of your eyes.
When I shoot with both eyes open I get two targets ,one over lapping the other. With the blinder in front of my right eye I get one nice clear image.
