This technique is aimed at training your nervous system and enhancing your vision. It bases its concept on the fact that one eye works perfectly than two, and that it captures fine details as well as relaying extra blurred images, several inches to the side of the clear image. The reason both eyes can’t help you maintain 100 percent focus is that the brain handles video stream from both eyes. That explains why it’s easier to hit the target at the right point with one eye closed than when both eyes are opened. This method has been used since time immemorial and is equally effective for those wearing glasses or lenses. The technique also gives you a better vision and understanding of the attack. You’ll gain sniper-like accuracy with this technique.
