I shoot with both eyes open. You can pick up the target faster that way. If you find that the target is getting blurry, that is usually an indication that you are holding your breath. If your eyes are deprived of oxygen for more than 2 seconds your vision starts going. Another reason to keep both eyes open is if you close one eye, you are tightening your face muscles which throws off your ability to focus with your open eye. Keep both eyes open, breath and focus on the target, not your pins. Practice this with all of your weapons and you will become a better shot.

ButchA, I know you are a good shooter but your post has me wondering if you really are left eye dominate? Sounds like your a lefty who is right eye domminate.
