Anti-blue ray grey lens capable of color fidelity

Abstract

The invention relates to an anti-blue ray grey lens capable of color fidelity, and the anti-blue-ray grey lens satisfies the following conditions that the transmittance at 620nm-760nm red light band is 68.73393%, the transmittance at 592nm-620nm orange light band is 10.1835%, the transmittance at 578nm-592nm yellow light band is 7.0255%, the transmittance at 500nm-578nm green light band is 11.36411%, the transmittance at 464nm-500nm cyan light band is 21.8626%, the transmittance at 446nm-464nm blue light band is 14.905%, and the transmittance at 400nm-446nm purple light band is 5.73%. When theproduct provided by the invention effectively filters blue light, the color coordinates of the transmission spectrum at the visible band of 400nm-760nm are close to the color coordinate value of thewhite point in the center, so that the anti-blue ray gray lens provided by the invention has the effect of color fidelity.

Description

technical field [0001] The invention relates to the field of protective lenses, in particular to a gray anti-blue 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 degener...

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
