Patent ID: 8568256

Claim:
A method for increasing the visual performance of a batter, comprising the steps of: a) pitching a series of baseballs to the batter; b) wherein the baseballs each have a cover portion and a seam portion, the seam portion comprising seams and stitches; c) wherein the seam portion of the baseballs is enhanced by having red seams made wider by using a red coloring agent to increase the width thereof to be about as wide as the stitches for the batter to better distinguish the seam portion from the cover portion of the baseballs; and, d) highlighting spin of a ball approaching the batter by providing eyeglasses to the batter with which to observe the pitched baseball, wherein the eyeglasses have left and right lens, wherein each lens comprises a different color, one color to make the seam portion become more apparent to the batter while the other color makes the ball less visible, wherein the batter is better able to recognize the spin of each incoming baseball, and wherein the visual performance and the batting performance of the batter are thereby improved.
