ASSEMBLY STRUCTURE FOR LENSES OF EYEGLASSES

摘要

An assembly structure for lenses of eyeglasses is provided, in which the frame thereof mainly has two inlay grooves respectively provided at the inner edges of lens mounting apertures. The frame also has recessed portions provided at both outer ends of the lens mounting apertures for fitting snugly with positioning blocks. The positioning blocks has snap-fit portions provided at the upper end edges thereof. The snap-fit portions allow the positioning blocks to be fitted snugly in the recessed portions and to be locked firmly onto the frame, so that the lenses can be held securely within the lens mounting apertures by the positioning blocks. The design of the positioning blocks can match the overall design of the frame, thus there is no such case as to destroy aesthetics of the appearance of the frame, and the frame has more diversified designs. Moreover, the lenses can be processed in simpler way.
