ABSTRACT:
Extended vision eyewear for hunters, security guards, motorcyclists, industrial workers, spectators, joggers, hikers and boy and girl watchers. The optical system reduces accidents and crime. The eyewear is comprised of a frame, a pair of reflectors mounted on the frame at about the eye level of a user, a pair of elongated slender arms having inner end portions mounted for rotation on a front center portion of the frame and a pair of reflectors joined by spherical joints to outer end portions of the slender arms. The slender arms are independently rotatable from non-operative positions adjacent to the front of the frame to operative positions forward of the frame. When the arms are at the forward operative positions, the reflectors are selectively rotatable about the spherical joints to extend the user's field of vision in lateral, vertical and rearward directions. When the optical system is not in use, the arms are stored adjacent to the front of the frame and the reflectors are stored adjacent to sides of the frame.
