Embedded shading plate type optical lens

Abstract

The invention relates to the technical field of the optical lens, and more specifically relates to an embedded shading plate type optical lens. The optical lens comprises a lens substrate, a shading plate is mounted at the upper side of the inner wall of the lens substrate, and the shading plate structure is a hollow and circular shading plate; a transmitting area is arranged in the shading plate,an anti-reflection film area is arranged on the surface of the transmitting area, an optical layer is arranged on the lens substrate, an anti-wear plating is arranged on the optical layer, an anti-oil layer is arranged on the anti-wear plating, and an anti-radiation layer is arranged on the anti-oil layer. The optical lens disclosed by the invention is novel in design and can effectively shelterthe light surrounding the optical lens, thereby enabling ray refractive angles between the optical lenses to be different, the mutual interference in the propagation process is reduced, a better anti-dazzle effect is realized, the vision is more clear and natural, the use effect is greatly improved, the oil resistance, the wear resistance and the radiation resistance of the optical lens are effectively improved.

Description

technical field [0001] The invention relates to a lens, in particular to an optical lens embedded with a shading sheet, and belongs to the technical field of optical lenses. Background technique [0002] Optical glass is mixed with oxides of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melted at high temperature in a platinum crucible, stirred evenly with ultrasonic waves, and removed air bubbles; The temperature is lowered slowly over time to avoid internal stress in the glass block. The cooled glass blocks must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to form optical lens blanks. [0003] With the advancement of science and technology and the change of human living habits, optical lenses are used more and more widely, but in daily life, mo...

Problems solved by technology

[0003] With the advancement of science and technology and the change of human living habits, optical lenses are used more and more widely, but in daily life, more and more people need to wear optical lenses. When people wear glasses, they often wear glasses under the hot sun or When driving at night, the vision will be blurred due to strong light stimulation, and there is a very high safety hazard. Therefore, it is necessary to design an optical lens with an embedded shading sheet
