A kind of anti-myopia lifting glasses

Abstract

The invention discloses a pair of myopia increase prevention eyeglasses which comprises an eyeglass frame composed of eyeglass frames, eyeglass legs and nose supports; a lens is arranged in each eyeglass frame, a nose support beam is integrally connected with the middle of the eyeglass frames, and the nose support beam, the nose supports and the eyeglass frames are integrally formed; an upper cover is arranged above the nose support beam, auxiliary nose supports are formed under the nose support beam, a lifting device is arranged between the nose support beam and the upper cover, and the auxiliary nose supports can vertically lift under the action of the lifting device; as the lifting device is adopted for vertically lifting the auxiliary nose supports, the eyeglass frames are relatively lifted down or lifted up, so that the pair of myopia increase prevention eyeglasses meets the requirements that people see near objects through lower light regions of the lenses and see far objects through upper light regions.

Description

Technical field [0001] The invention relates to the technical field of glasses, in particular to a kind of glasses for preventing myopia from rising. Background technique [0002] Most of the glasses that people wear nowadays are progressive lenses. The progressive lenses are based on the French Bernard Maitenaz's 8 years of research. In 1959, the principle of progressive lenses was applied to glasses for the first time. Between the near-use zones, in a gradual diopter change, from the distance-use power to the near-use power, the far-use zone and the near-use zone are organically connected together, so that you can see the distance at the same time on one lens. Different luminosity required for distance, middle distance and short distance. Progressive lenses are also called progressive lenses. As the name implies, there are multiple focal points on a lens. People can increase the curvature of the front surface of the lens continuously from the top to the bottom, and the refract...

Problems solved by technology

The telescopic lifting mechanism is a telescopic structure of multiple sleeves. Springs are arranged in the telescopic sleeves. Locking devices and triggers or buttons are installed on the temples or frames. The nose pads of this invention are too far away from the lenses, which does not meet the configuration of lenses on the market. , the upper lock is easy to touch the forehead and too many devices exposed outside the frame affect sight and attention, and the button operation is also extremely inconvenient
