Abstract
A golf ball has indicia adapted to allow a user to align the indicia with at least one of an intended direction of travel of the ball and a club head of a club the user will use to strike the ball. The indicia can be three parallel lines extending around a portion the golf ball. A golf club can be provided with a marking on the club head adapted to align with the indicia on the golf ball.

A golf ball with indicia for alignment comprising:
- a golf ball;
- and
- indicia on the golf ball, said indicia comprising only three parallel lines presenting an image for a vernier acuity task extending around a portion of the golf ball at spaced intervals, the three parallel lines comprising two outer lines and an inner line located between the two outer lines, each of said two outer lines having a width smaller than a width of said inner line;
- said indicia adapted to allow a user to align the indicia with at least one of an intended direction of travel of the ball and a club head of a club the user will use to strike the ball, said indicia spanning a total distance in a range of about 0.42 inches to about 0.84 inches, whereby said user performs the vernier acuity task to align the indicia.
