US Patent 10279237 Sports training apparatus and method

A sports training apparatus occludes peripheral vision of each eye across the nose region of a player by creating a visual divide that extends from and immediately adjacent to the nose along the central sagittal plane. In various embodiments, the visual divide is extendible, removable and replaceable, pivotal, and may incorporate scribes to vary shape or geometry. The visual divide may further be mounted from a pair of glasses without lenses, though other embodiments with and without lenses are contemplated. The eye divider is used to align or confirm alignment of a player properly to ensure that the player batter has both eyes facing in the proper direction.
