Abstract

Eyeglasses comprise a pair of spectacles having primary lenses and an auxiliary lens assembly attached to the spectacles. The auxiliary lens assembly is secured by a subframe that includes at least one arm having a magnet at one end to co-operate with a magnet provided on the spectacles. A hinge is provided on the subframe at the opposite end of the arm to allow the auxiliary lens assembly to move from a position in which the primary lenses are covered to a position in which they are exposed.
