Abstract: A device for aligning a golfer's dominant eye with a golf ball and cup comprising a mask adapted to be secured to the head of a golfer. The mask covers the non-dominant eye and has an opening therein located and sized for allowing the dominant eye to view both the ball and the cup. A weighted cord is attached to the mask in the line of sight of the dominant eye for enabling the dominant eye to be vertically aligned over or behind a golf ball for proper alignment in the act of putting.
