Nike Vapor Strobe Glasses work by blocking most of the vision of either both eyes or one eye at a time for eight different periods of time. Nike made it so the higher the setting, the less time one sees out of each cycle. The athlete wears the glasses while doing training drills. The Nike Strobe Training Glasses teach the user to more efficiently judge distances, depth, movements, position of self and objects of regard, and hand-eye coordination.
