| Abstract: |
A pair of spectacles which enable a forward facing user to view objects behind the user. A pair of swing arms is rotatably attached to the forward portion of the spectacles' temples. The swing arms are thin narrow members whose shapes are similar to the temples. A rear vision member is connected by a spherical joint to one end of each swing arm. The swing arms are individually rotatable in one direction for positioning the rear vision members at operative positions ahead of the spectacles' eyepiece and rotatable in the opposite direction for storing the swing arms and rear vision members behind the eyepiece. At the stored positions, the swing arms and rear vision members are adjacent to the outer surface of the temples and aligned with the temples. The spectacles have the appearance of a conventional pair of spectacles when the swing arms and rear vision members are at their stored positions. In the first aspect of the invention, the swing arms are rotatable about horizontal axes disposed in transverse relationship to the temples. In the second aspect of the invention, the swing arms are rotatable about vertical axes disposed in parallel relationship to the temples.
