Abstract
A lens fixing apparatus for rimless spectacles includes a holder combined to the temple of the rimless spectacles or one side of the bridge. Both surfaces of the lens are compressively fixed along the inner circumference thereof, and a fixing frame has a compression surface. The rear surface of the lens contacts the front surface of the fixing frame and the rear surface of the fixing frame has a slanted surface formed thereon, the thickness thereof gradually increasing as it extends outwardly. The fixing frame has an elongated hole of a predetermined length formed through the surface opposing the lens, longitudinally along the compression surface.
