Problems solved by technology

[0003] The seaside scenery is pleasant, but the light is strong, and the anti-blue light lens has a potential development market. However, the current anti-blue light lens has the following problems: 1. The lens is not waterproof, and water stains adhere to the surface of the lens, affecting vision and causing inconvenience in use; 2. . Due to the salt in seawater, it is corrosive to a certain extent. When the anti-blue light coating encounters seawater environment, it is easy to peel off, fade and fail to prevent blue light

Abstract

The invention relates to an angstrom anti-blue lens and a preparation method thereof. The lens includes a substrate, a priming layer, a composite film layer and a protective layer. The priming layer is made of silicon dioxide or a silicon-aluminum mixture, and has a thickness of 800+ / -100 angstroms. The composite film layer includes a film formed by alternately stacking 4 layers, 6 layers or 8 layers of high refractive index layers and low refractive index layers, the high refractive index layer is made of any one of Ta2O5, Ti3O5 or Nb2O5 and has a thickness of 500+ / -100 angstroms, and the lowrefractive index layer is made of silica or a silicon-aluminum mixture. The prepared angstrom anti-blue lens has a good effect of reflecting light with a wavelength of 340-500 nm and has an anti-bluelight effect; after the lens is subjected to salt water boiling and pure water soaking cycle 11 times, no film layer falls off in a 100-square test, and the angstrom anti-blue lens has good film layer adhesive force. The angstrom anti-blue lens has a good seawater corrosion resistance, and is especially suitable for the seaside environment.

Description

technical field [0001] The invention relates to the field of optical lenses, in particular to an Amy anti-blue light lens and a preparation method thereof. Background technique [0002] Blue light is an important part of visible light. There is no separate white light in nature itself. Blue light is mixed with green light and red light to form white light. Green light and red light have less energy and are less irritating to the eyes. Blue light has a short wavelength and high energy, and can directly penetrate the lens to reach the macular area of ​​the eye, especially short-wave blue light, whose wavelength is between 400nm and 480nm. High energy light. Blue light within this wavelength will increase the amount of toxins in the macular area of ​​the eye, seriously threatening the health of our fundus. [0003] The seaside scenery is pleasant, but the light is strong, and the anti-blue light lens has a potential development market. However, the current anti-blue light len...
