Abstract: An eyeglass structure includes a front light-penetrable portion flanked by two parallel guide walls each having a free end with a leg pivotal connection portion; a rear frame portion flanked by two sliding bodies each having a free end with a stop wall, with each sliding body disposed between the guide walls, and each stop wall between a corresponding one of the sliding bodies and a corresponding one of the leg pivotal connection portions; a demountable connection portion connected to the front light-penetrable portion and the rear frame portion; and two legs pivotally connected to the leg pivotal connection portions to stop the stop walls, respectively. Hence, the eyeglass structure enables the front light-penetrable portion and rear frame portion to be firmly coupled together.

Abstract: The present invention discloses an eyeglass nose bridge structure having an included angle between its two nose pads that is able to fit in with any eyeglass nose bridge openings of different specifications, so that the eyeglass nose bridge structure can be used universally for lenses or glasses of different specifications. The eyeglass nose bridge structure includes a first pillar made of a soft material and a positioning portion. The positioning portion includes a positioning hole and a second pillar made of a soft material, and either ends of the first pillar are connected to a separate nose pad, and one end of the second pillar is connected in between the two ends of the first pillar. The invention can achieve the effects of lowering development and manufacturing costs and enhancing the assembling efficiency and the overall aesthetic appearance of the glasses.

Abstract: A nose-rest mechanism for safety glasses includes a lens unit, a fixing device, and a nose piece. The nose piece includes two nose rests and a first extended section upward extended from between the two nose rests. The fixing device defines an inner receiving space adapted to receive and confine a middle bridge section of the lens unit and the first extended section of the nose piece thereto. The nose piece is provided on the first extended section with at least one projecting portion or at least one through hole for engaging with at least one retaining hole on the fixing device or at least one projecting section on the lens unit, respectively, enabling the nose piece to be easily, stably, and detachably connected to the lens unit via the fixing device while maintaining the safety glasses in a beautiful appearance.
