im right handed right eye dominant...

that being said, i shoot both eyes open for everything except high powered scopes on my rifles...even upto 4x or so i shoot both eyes open...

found im more accurate and quicker on target and can follow through with the shot better and also keeps me from getting tunnel vision as bad and i can see the "big picture" opposed to closing 1 eye and looking through a peep and focusing on the target and sight with the only eye i have open...cant see a whole lot other than the target shooting with 1 eye open....

took a little while to get used to but my groups shrank with the bow and pistols...
