An eyeglasses assembly includes two lenses, a frame, and two positioning blocks. The frame includes two frame portions. Each frame portion includes upper and lower portions spaced from each other by a notch. The upper portion includes an insertion hole. The lower portion includes an engaging groove aligned with the insertion hole. At least one engaging hole extends from an outer surface of the lower portion to the engaging groove in a thickness direction. Each positioning block is mounted in an associated insertion hole and an associated engaging groove. Each positioning block includes at least one assembling hole to be aligned with the at least one engaging hole. Each of a plurality of fasteners extends through the at least one assembling hole of an associated one of the two positioning blocks and the at least one engaging hole of the associated lower portion.

A pair of eyeglasses includes a front with two lenses installed in the two openings thereof. Two lugs respectively extend from two ends of the front and each have a slot communicating with the opening corresponding thereto. Two threaded holes are respectively defined through the two ends of the front and communicate with the two slots. Two screws threadedly extend through the two threaded holes to narrow the slots to secure the two lenses in the front. The two lugs are clamped between the two connectors and two securing members by bolts extending through the securing members, the lugs and the two connectors, and connected with two positioning members. The lenses can be replaced by unscrewing the bolts and the screws.

A flexible eyewear assembly is described. The assembly includes first and second rigid frame portions each having an opening therein. The assembly also includes a flexible component. The flexible component includes first and second lens retainers configured to engage the first and second rigid frame portions along an inner edge thereof adjacent the respective opening, and sized to retain first and second lenses therein; and a flexible bridge portion connecting the first lens retainer to the second lens retainer, to connect the first and second rigid frame portions with separation therebetween, when the first and second lens retainers are engaged with the flexible component.

Glasses include a glass upper frame, a glass lower frame, the lens, and a bridge. Each of two ends of the glass upper frame dents to form a downward-opening receiving cavity of predetermined depth. Each of two ends of the glass lower frame dents to form a receiving cavity of predetermined depth. Magnetic elements are fitted snugly into the receiving cavities. An elevated portion is centrally disposed at the glass lower frame and corresponds in position to a slot dentedly-formed at the bridge such that a complete stop groove is formed along the glass lower frame when the bridge is fitted to the glass lower frame. The bottom edge of the glass upper frame dents to form a groove. Each of the two ends of the glass upper frame dents to form an inward-opening dented portion. The groove, dented portions, stop groove, and bridge jointly hold the lens.
