Spectacle lens with edge dropping resistance, installation firmness and convenience for view transformation

Abstract

The invention discloses a spectacle lens with edge dropping resistance, installation firmness and convenience for view transformation. The spectacle lens comprises a lens body, a shortsighted lens, adistant vision lens, a breakage-proof glass frame, a hardening film, an ultraviolet filter film, an oil-resistant glass sheet, an anti-blue film, a hemispherical block, an edge groove and a hemispherical groove. The spectacle lens disclosed by the invention is reasonable in design, the function of conveniently proximally and distantly transforming the clear fields of view on the same spectacle lens is realized, the effect of performing local blue filtering on the spectacle lens is achieved, the edge dropping resistance of the spectacle lens is enhanced, the mounting linkage structure of the traditional spectacle lens and spectacle frame is changed, and the firmness is high. The breakage-proof glass frame is increased on the edge of the lens body, so that the effect of enhancing the edge dropping resistance of the spectacle lens is achieved, and distant things can be clearly observed by enabling naked eyes to look up through the distant vision lens, or near things can be clearly observed by enabling the naked eyes to look down through the shortsighted lens.

Description

technical field [0001] The invention relates to a spectacle lens, in particular to a spectacle lens whose edge is anti-drop and is firmly installed and which is convenient for field of view conversion, and belongs to the technical field of spectacle lens applications. Background technique [0002] There are many types of spectacle lenses, such as photochromic lenses, resin lenses, aspheric lenses, progressive multi-focal lenses, etc. Each has different functions, and you should choose according to your own needs, such as often facing the computer, TV or studying and working under the light Therefore, it is necessary to choose lenses with radiation protection function to protect eyesight and relieve eye fatigue. [0003] The edge of the general spectacle lens and some of the spectacle lenses are not installed in the full frame of the eye frame, and although the spectacle lenses have been chamfered accordingly, there are also cases where the edges and corners are damaged due t...

AI Technical Summary

Problems solved by technology

[0003] The edge of the general spectacle lens and some of the spectacle lenses are not installed in the full frame of the eye frame, and although the spectacle lenses have been chamfered accordingly, there are also cases where the edges and corners are damaged due to the accidental drop of the spectacle lens. The spectacle lens will also loosen, so it needs to be improved in terms of the protection of the edge of the spectacle lens and the firmness of the installation. The traditional spectacle lens lacks the structural function of convenient far-near conversion on the same spectacle lens to clearly observe the field of view and the close observation. The reflected light of things performs the blue light filtering function, so that when the viewing position of the glasses lens is kept inconvenient, the visual effect of the glasses wearer observing distant or near things is not good, and it is blurred
