ABSTRACT:
A pair of eyeglasses is provided for sports training, and more specifically for training the player to keep the player's eyes on an approaching ball for batting or for swinging a racket. The pair of glasses, have a position adjustable pair of lenses each having an opaque peripheral region and a transparent central region. Initial adjustment of the lenses is achieved utilizing a removable cover element overlaying the transparent central region wherein the cover element has a viewing aperture. A method is provided wherein the player wears a pair of the glasses, adjusts the positions of the lenses to correspond to the positions of the pupillary disks of the player until the player can view a single focal element through each aperture, removing the cover elements from the lenses, and batting at a moving ball while wearing the eyeglasses.
