Should you zero a red dot with one eye or both eyes open? Is there a POI shift when using one eye vs. two?

Whatever you are more comfortable with.  Dots are straight glass and it makes no odds.  Me personally, I like to zero at 200 and I find with dots at extended range for zeroing it is best for me to shut one eye.  Once its zeroed, I'm pretty much always both eyes open.
