Both eyes open. It took awhile to get used to it, but I'm glad I stuck with it. Now it seems that it's hard to see much when I shoot with one eye closed.

Both eyes open. No pun intended but you'll see what you've been missing. Faster target acquisition, too.

Both open,but i do squint my left eye a little.
