Optical lens with strong light weakening function

Abstract

The invention discloses an optical lens with a strong light weakening function. The optical lens comprises a lens body, a coating film, a first strong light reflection block, a receiving layer, an inwards concaved layer, a blue light reflection layer, a dust preventing layer, a second strong light reflection block and a glass layer. The invention provides the optical lens with the strong light weakening function. The first strong light reflection block and the second strong light reflection block are added to the upper end and the lower end of the receiving layer in the lens body and both adopt wavy structures; when strong light irradiates the lens body, strong light is scattered multiple times through repeated strong light refraction by the aid of the wavy structures of the first strong light reflection block and the second strong light reflection block, finally, strong light penetrating through the lens body is scattered and refracted multiple times and is not dazzling any more, and harm of the strong light to pupils is greatly reduced. The lens has a blue light reflection function by means of the added blue light reflection layer in the lens body; the dust preventing layer is arranged on the innermost layer of the lens body, so that the lens does not easily gather dust during use.

Description

technical field [0001] The invention relates to a cultivation frame, in particular to an optical lens with the function of reducing strong light, and belongs to the application field of optical lenses. Background technique [0002] Optical lenses are mixed with high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, then melted at high temperature, stirred evenly with ultrasonic waves, and removed air bubbles; Lower the temperature 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. After further processing, it becomes an optical lens, which is widely used in human production and life, the most common application, and the lens of myopia glasses used by...

AI Technical Summary

Problems solved by technology

[0003] However, the existing optical lenses used for myopia glasses still have certain defects in use. The appearance of some lenses and the curvature of the overall curved surface do not conform to the public aesthetics, and they do not have the function of weakening strong light when used, but some are used for astigmatism. The patient's eyes, when facing strong light, strengthen the light instead, causing invisible damage to the pupils used. Long-term use may even damage vision and affect the health of the pupils.
