id like to hear from someone that used one with that same design. the looks like it would give me a headach. something like that that close to your eye would probably just be a nasty blur while trying to focus on the pin and target. but i never used one so i dont know. i just know that our eyes are made to pretty much focus on one object not 3. thats why i used a peep that is the same size or slightly bigger than my sight housing when im at full draw. center the housing in the peep and put the pin on the target. eye is always focused on the target. thats just how i shoot..i have a bad astigmatism which screws with the light and sharpness..it works for me..and i dont shoot with glasses or contacts lol. i need to start though..
