Lens and glasses

Abstract

The invention discloses a lens and glasses, and relates to the technical field of optical lenses. The main purpose of the lens and the glasses is to regulate visibility of the lens. According to the main technical scheme of the lens and the glasses, the lens comprises polarizers and liquid crystal boxes, the polarizers are arranged on one sides of the liquid crystal boxes or in the liquid crystalboxes, each liquid crystal box comprises an electrode assembly, a liquid crystal layer and a diffraction lens grating layer, wherein the electrode assemblies are used for adjusting the orientation ofliquid crystals in the liquid crystal layers, and the liquid crystal layers are arranged on one sides of the diffraction lens grating layers, so that the liquid crystals in the liquid crystal layers are in contact with the concave-convex surfaces of the diffraction lens grating layers. The lens and the glasses are mainly used for correcting myopia of human eyes.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a lens and glasses. Background technique [0002] With the gradual deepening of people's eye fatigue, more and more people need to wear myopia glasses. In the prior art, the lenses of myopia glasses generally use geometric lenses. It is projected on the retina of the human eye to correct myopia. However, the diopter of the geometric lens is generally fixed. When the diopter needs to be adjusted, the only way to change the myopia lens is very troublesome. , has brought a lot of inconvenience to people's life. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a lens and glasses, the main purpose of which is to adjust the diopter of the myopia lens. [0004] In order to achieve the above object, the present invention mainly provides the following technical solutions: [0005] On the one hand, an embodiment of the present...
