One eye or two eyes open?

[Moon]

I shoot with two eyes, but I barely look through my second eye 75% of the shot. I only use the second eye for referencing the target as I'm getting aimed on it after first drawing back. Once I'm aimed on it I completely blur out my vision from my second eye or even close it and fine tune my aiming with my dominant eye before taking the shot. If feel it helps me get on my target much faster this way.
