Problems solved by technology

[0006] For anti-reflection coatings, green anti-reflection coatings are generally used in the prior art. This is because the green anti-reflection coating is easier to control. Even if the thickness error of a certain layer of the anti-reflection coating is large, it has little effect on the color of the coating. It is also the reason why most of the lenses with anti-reflection coating on the market look green or blue under the sunlight. If an anti-reflection coating is added to the anti-blue light lens, this will affect the appearance
At present, there is no anti-blue light glasses lens with anti-reflection coating and natural appearance on the market

Embodiment Construction

[0017] Such as figure 1 As shown, the anti-reflection film for spectacle lenses provided by the present invention includes a first silicon dioxide layer 1, a first zirconium oxide layer 2, a second silicon dioxide layer 3, a first titanium oxide layer in the order of being away from the lens substrate 100. Layer 4, first aluminum oxide layer 5, second zirconium oxide layer 6, first silicon carbonate layer 7, second titanium oxide layer 8, second silicon carbonate layer 9, second aluminum oxide layer 10, third silicon dioxide layer 11 , in addition, it also includes a conductive layer 12 formed of indium tin oxide.

[0018] In the present invention, the anti-reflection film is used for anti-blue light glasses.

[0019] According to the invention, the antireflection film comprises at least one high-refractive-index layer and at least one low-refractive-index layer. It is formed into a structure of 7-11 layers, and the high-refractive-index layers and low-refractive-index layer...

Abstract

The invention discloses an antireflection film used in an anti-blue light lens which is natural in appearance, simple in making process and low in production cost. The antireflection film, according to a sequence away from the lens substrate, sequentially comprises a first silica layer, a first zirconia layer, a second silica layer, a first titania layer, a first alumina layer, a second zirconia layer, a first silicon carbonate layer, a second titania layer, a second silicon carbonate layer, a second alumina layer and a third silica layer, and also comprises a conductive layer formed by indium tin oxide.

Description

technical field [0001] The invention relates to an anti-reflection film, in particular to an anti-reflection film used in an anti-blue light spectacle lens. Background technique [0002] In the prior art, research on anti-blue light glasses is in full swing, especially with the development of Internet technology, anti-radiation glasses including anti-blue light and anti-ultraviolet radiation have been widely used. Generally speaking, the visible light band is approximately the spectral range from a wavelength of 380 nanometers (nm) to a wavelength of 780 nm. The portion from about 380 nm to about 500 nm substantially corresponds to high-energy blue light. Blue light is very harmful to the human eye, especially the retina. If the human eye is exposed to blue light for a long time, it may cause serious ophthalmic diseases, such as age-related macular degeneration, and even lead to blindness. However, the 465nm to 495nm part of the above-mentioned blue light band is beneficia...
