Left eye dominant golfer should put ball position two balls in front of center whereas a right eye dominant golfer should place their ball center of stance. Ball position should be based on center mass, i.e. belt buckle or belly button. If a golfer uses their feet to decide ball position where would that leave Kenny Perry? Ball position is constant which is why we use the beltbuckle. To determine eye dominance place a ball on the ground. Put hands together allowing a space between them big enough to see the ball. Close left eye. If ball is still visible you are right eye dominant. If the ball disappears, you are left eye dominant.
