Liquid self-adapted focusing glasses

Abstract

The invention relates to liquid self-adapted focusing glasses comprising glasses frames, glasses legs, lenses mounted on the glasses frames, an interpupillary distance adjusting device and a degree adjusting rod, wherein the glasses frames are provided with the front and back lenses in a sealed manner; the front and back lenses are made of different materials to form a closed chamber for containing liquid with the glasses frames; the interpupillary distance adjusting device is mounted on a connecting frame rod between the two glasses frames; the glasses legs are connected with the glasses frames through bolts; each glasses leg is internally provided with an injection device; the injection device comprises a push rod, a piston and a spring; and a rubber hose is used for conducting the liquid between a closed cavity of the glasses legs and the closed chamber formed by the lenses and the glasses frames. A user can adjust the glasses into myopia glasses or hypermetropia glasses according to own different conditions and can change the degrees of the lenses according to the requirements of the user to achieve the requirements of the user. The liquid self-adapted focusing glasses have the advantages of economy, environmental protection and convenience.

Description

technical field [0001] The invention relates to liquid self-adaptive focusing glasses, belonging to the technical fields of mechanical engineering, optical engineering, and material science and engineering. Background technique [0002] A pair of existing resin glasses can only meet the requirements of one degree of prescription. Due to the wear and tear of the glasses or the deepening of the prescription, the glasses need to be replaced regularly. The life of the glasses is very limited, so the cost of glasses is greatly increased. Usually used glasses can only be discarded, causing huge waste. Compared with conventional glasses, liquid adaptive focusing glasses can adjust the diopter to achieve different degrees of change, and the cost of use is lower and more economical. [0003] The patent No. 03233686.1 proposes a spectacle lens with adjustable focal length, which uses the filled liquid to change the diopter between the transparent zoom lenses attached to the lens to a...

Problems solved by technology

[0004] In view of the defects in the existing technology, the purpose of the invention is to provide a liquid self-adaptive focusing glasses, which solves the problem of separation of the injection device from the glasses, the inability to achieve a wide range of focus adjustment, and the inability to achieve relatively fine degree adjustment, sealing and aesthetics. To solve such problems, the mechanical injection device is used to fill and extract the transparent liquid into and out of the lens, thereby changing the curvature of the inner film of the lens and realizing the self-adaptive adjustment of the focal length in the liquid state
