Thin-steel interchangeable-lens eyeglass structure

Abstract

This invention relates to a thin steel replaceable lens eyeglass structure. The main features include a support member at the front end of the frame and a connecting member at the rear end. An elastic limiting member connects the frame and the connecting member. A retaining seat protrudes from the front end of the nose bridge, which is attached to the bottom of the connecting member, allowing the attached lens to be positioned correspondingly at the front end of the frame. A locking slot is provided at the position of the supporting member corresponding to the attached lens, and a nose bridge is formed below the locking slot corresponding to the attached lens, allowing the attached lens to be clamped and fixed by the locking slot and the retaining seat. Therefore, in the use of thin steel eyeglasses, not only can they provide vision correction, but they can also be fitted with additional lenses to block sunlight and prevent it from shining into the eyes, thus enhancing their overall practicality.
