Not when you're standing over the ball, but when you're first assessing the line of your putt, do you use both eyes, or close one when you're lining up your putts?
Why would you only use one eye? You would get no perception of depth.
Think Angel Cabrera does that?If I'm using my putter as a plumb line, I'll close one eye. Other than that, I keep them both open.
