Abstract
A fashionable pair of spectacles with a pair of dual pivot rear vision elements for viewing objects behind a forward facing user. The spectacles include a binocular eyepiece, a pair of symmetrically opposite temples rotatably attached to opposite end portions of the eyepiece, a pair of arms having windows for viewing dual pivot elements in their operative positions rotatably attached to the end portions of the eyepiece, and the pair of dual pivot elements having reflective surfaces rotatably attached to the arms. The dual pivot elements are rotatable about their attachments to the arms from non-operative stored positions alongside the temples whereat their reflective surfaces are in facing relationship to the user to operative positions whereat the arms extend forward of the eyepiece, the rear vision elements extend outwardly from the arms and the reflective surfaces of the elements are in facing relationship to the user.
