Abstract
Disclosed herein is a spectacles and sunshade clip assembly. The assembly comprises spectacles including a pair of lens frames, and a pair of hinges affixed to opposite outer ends of the lens, and a sunshade clip including a pair of sunshade lens frames connected to each other by means of a bridge. The sunshade clip further comprises a pair of magnet ribs affixed to opposite outer ends of the sunshade lens frames to linearly extend across only a relatively short distance in a longitudinal direction of the sunshade clip. A respective one of the hinges provided at the spectacles is spaced apart forward from a reference line having a radius of curvature defined by inner surfaces of the lens frames, so that a portion thereof, coming into contact with a corresponding one of the lens frames, forms a forwardly-protruding portion. The forwardly-protruding portion is formed as a recessed magnet-mounting portion to receive a corresponding one of the magnets.
