Color fidelity anti-blue light tawny lens

Abstract

The invention relates to a color fidelity anti-blue light tawny lens. The anti-blue light tawny lens meets the following conditions: the transmittance at a red light band of 620 nm to 760 nm is 70.158%, the transmittance at an orange light band of 592 nm to 620 nm is 12.57075%, the transmittance at a yellow light band of 578nm to 592nm is 8.9585%, the transmittance at a green light band of 500nm to 578nm is 10.27011%, the transmittance at an indigo band of 464nm to 500nm is 9.7716%, the transmittance at a blue light band of 446nm to 464nm is 4.874%, and the transmittance at a purple light bandof 400nm to 446nm is 1.75%. While the product provided by the invention effectively filters the blue light, the transmitted spectrum color coordinate of a visible light band of 400 nm to 760 nm is close to the color coordinate value of the central white point, so that the anti-blue light tawny lens provided by the invention has a color fidelity effect.

Description

technical field [0001] The invention relates to the field of protective lenses, in particular to an anti-blue light brown lens which has the function of preventing blue light and can realize color preservation. Background technique [0002] Blue light is part of the natural visible light, which is emitted by sunlight and electronic screens. 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, which can directly penetrate the lens and reach the macular area of ​​the eye, causing macular degeneration. [0003] With the widespread application of 3C products, more and more people bow their heads. The blue light of 3C products will cause serious harm to people's eyes, causing more and more people with eye diseases such as macula and...

Problems solved by technology

[0005] However, because anti-blue light glasses on the market filter harmful blue light in the short-wavelength blue light region, according to the principle of complementary colors, the lens will appear slightly yellowish visually, and the image presented through the blue light lens is often yellowish, which has a negative effect on the visual effect of the image itself. Great adverse effects, for example: the white pattern will turn light yellow or yellow after passing through the anti-blue light lens, which will affect the visual experience and is even more unfriendly to drivers
