An easy-to-wear pressure-adjustable legless reading glasses frame

Abstract

The invention provides a pressure-adjustable leg-free presbyopic glasses frame convenient to wear, and relates to the technical field of glasses frames. The pressure-adjustable leg-free presbyopic glasses frame convenient to wear comprises a connecting plate. Bayonets are fixedly installed at the left end and the right end of the connecting plate, lenses are fixedly connected into the bayonets, connecting bases are fixedly connected to the ends, away from the bayonets, of the lenses, a hanging rope is fixedly connected between the connecting bases, sliding grooves are formed in the connectingplate, and rotating shafts are slidably connected into the sliding grooves. The design of supporting legs on two sides of the traditional spectacle frame is abandoned. The presbyopic glasses are moreconvenient to wear and take. Meanwhile, the overall weight of the presbyopic glasses is reduced, the wearing comfort is improved, the presbyopic glasses can be suitable for people with different nosebridge widths, the initial torsion of the internal torsion spring can be adjusted, the phenomenon that the torsion spring loses restoring force due to long-time use is avoided, and the service life ofthe glasses frame is prolonged.

Description

technical field [0001] The invention relates to the technical field of spectacle frames, in particular to a pressure-adjustable legless reading spectacle frame that is easy to wear. Background technique [0002] Presbyopic glasses, also known as presbyopic glasses or presbyopic glasses, are a type of optical product. The glasses used by people with presbyopia belong to a kind of convex lens. Light converges and is imaged on the retina through the lens. At present, wearing presbyopia glasses is the best way to solve presbyopia. [0003] And presbyopic glasses are to solve the difficulty of presbyopia for near-distance vision, and there is no obvious improvement for distant vision. In addition, wearing presbyopic glasses for a long time will also aggravate eye fatigue. Therefore, presbyopic glasses are not used in daily life. For long-term wearing, it will be worn repeatedly according to the actual situation, while the frame of traditional presbyopic glasses is mainly compose...

Problems solved by technology

[0003] And presbyopic glasses are to solve the difficulty of presbyopia for near-distance vision, and there is no obvious improvement for distant vision. In addition, wearing presbyopic glasses for a long time will also aggravate eye fatigue. Therefore, presbyopic glasses are not used in daily life. For long-term wearing, it will be worn repeatedly according to the actual situation, while the frame of traditional presbyopic glasses is mainly composed of foldable leg supports on both sides. During the wearing process, the legs need to be opened, and then Placed above the ears, the operation is complicated and cumbersome, and increases the overall weight of the glasses, causing discomfort to the wearer's nose bridge and ears
