During the conditioning process, the player works from the tee and uses soft-toss techniques to ensure proper positioning of the head and eyes.  The player then tracks balls at speeds from 60 to 150 miles per hour, conditioning the ocular muscle to ‘see’ the ball through the hitting zone. 

Once the eyes are conditioned, a player has more time to adjust to pitches during a game because he/she is seeing the ball further out, and is able to keep the ball in his/her central vision through the hitting zone, taking away the peripheral aspect of hitting. 

Once a player is successfully tracking a ball at over 100 miles per hour, a 60 to 95 mile per hour pitch is not as difficult to hit.  As with any other muscle, the eyes are conditioned to achieve muscle memory, which must be maintained through continual training.
