Abstract
This invention provides a clip-on member 1 includes a lens mounting rod 2 to which clip-on lenses are mounted, and a pair of upper clipping arms 4 and another pair of lower clipping arms 5 made of elastic members for attachment to the eyeglass frame. The upper clipping arms 4 include an upper hooking part 4a and another upper hooking part 4b with which the upper clipping arms 4 are fitted and mounted to the brow part of the spectacle frame from above. The lower clipping arm 5 includes an arm part 7a, an arm part 7b, and a pinching part 8. The arm parts 7a and 7b have left engagement part Sa and right engagement part Sb respectively held by the holding parts 6a and 6b, and placed at the nasal area of the spectacle frame between its right and left lenses. The lower left and right hooking parts 7a and 7b, as an extension of the clipping arms 7aand 7b, exercise theft elastic force towards the opposite sides, thus moving away from each other.
