[0002] At present, in the prior art, the nose pads of plastic frames or plate frames are generally integrally formed on the frame, that is, the nose pads are directly combined with the frame and cannot be replaced; some nose pads are formed separately from the frame and then fixed by screws On the frame, it is necessary to use a screwdriver and other tools to remove the screws before replacing the nose pads, which is inconvenient to replace. With the above nose pads, the pupil center of the wearer and the optical center of the lens cannot be adjusted, and the optical performance cannot reach the optimum. good

The invention discloses a pair of glasses with replaceable nose supports. The glasses comprise a bracket and two lenses. The bracket comprises a frame and two legs. The two legs are connected to the two ends of the frame respectively. The frame is mainly composed of the nose supports, two rings where the lenses are embedded respectively and a middle beam located between the two rings and connected with the two rings. Nose support mounting bases are mounted at the middle beam, and clamping grooves are formed in the nose support mounting bases. Clamping pillars capable of being inserted into the clamping grooves are arranged on the nose supports, and the nose supports are fixed to the frame through insertion matching between the clamping pillars and the clamping grooves. The matching contact surfaces of the clamping pillars and the clamping grooves are all in a sawtooth shape. According to the glasses, the optimal distance between the pupil centers of a glass wearer and the optical centers of the lenses is adjusted by replacing the nose supports of different sizes and controlling the insertion depth, and therefore the optimal performance of the lenses can achieve the optimal effect.
Description
technical field [0001] The invention relates to a nose pad replaceable spectacles, which belongs to the technical field of spectacles production. Background technique [0002] At present, in the prior art, the nose pads of plastic frames or plate frames are generally integrally formed on the frame, that is, the nose pads are directly combined with the frame and cannot be replaced; some nose pads are formed separately from the frame and then fixed by screws On the frame, it is necessary to use a screwdriver and other tools to remove the screws before replacing the nose pads, which is inconvenient to replace. With the above nose pads, the pupil center of the wearer and the optical center of the lens cannot be adjusted, and the optical performance cannot reach the optimum. good. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a nose pad replaceable glasses, which can adjust...
