Abstract

Vision training eyewear include lenses having a plurality of obscuration zones. The obscuration zones are individually switchable to provide light emission or attenuation that can interfere with normal vision of the wearer. A pattern or sequence of patterns can be selectively activated at a fixed or variable rate while a trainee is exposed to a test situation.
