Abstract
The invention relates to a blue light-resistant tawny lens with color fidelity, which meets the following conditions: the transmittance of the material in a red light wave band of 620nm-760nm is 70.158%, the transmittance of the material in an orange light wave band of 592nm-620nm is 12.57075%, the transmittance of the material in a yellow light wave band of 578nm-592nm is 8.9585%, the transmittance of the material in a green light wave band of 500nm-578nm is 10.27011%, the transmittance of the material in a cyan light wave band of 464nm-500nm is 9.7716%, the transmittance of the material in a blue light wave band of 446nm-464nm is 4.874%, and the transmittance of the material in a violet light wave band of 400nm-446nm is 1.75%. The product of the invention effectively filters blue light, and the color coordinate of the transmission spectrum in the visible light wave band of 400nm-760nm is close to the color coordinate value of the central white point, so that the blue light-proof tawny lens has the effect of color fidelity.
Description
Technical Field
The invention relates to the field of protective lenses, in particular to a blue light-resistant tawny lens which has a blue light-resistant function and can realize color fidelity.
Background
Blue light is a part of natural visible light, and both sunlight and electronic screens emit blue light. Blue light is an important component of visible light, natural world does not have independent white light, and the blue light, green light and red light are mixed to form white light. The green light and the red light have small energy, small stimulation to eyes, short blue light wave and high energy, and can directly penetrate through crystalline lens to directly reach the macular area of the eyes, thereby causing macular degeneration.
With the common application of 3C products, the lower head family is more and more, the blue light of the 3C products can cause serious harm to eyes of people, and people suffering from eye diseases such as macula lutea and degeneration are more and more, so that the prevention of blue light injury becomes a consensus of people.
Prevent that blue light glasses can effectively reduce the lasting injury of blue light to eyes, through portable spectral analysis appearance contrast detection, use and prevent behind the blue light glasses, the blue light intensity that the cell-phone screen sent has obtained effective suppression, has reduced the injury of harmful blue light to eyes.
However, in the commercially available blue-light-proof glasses, harmful blue light is filtered in a blue light region with a short wavelength, and according to the complementary color principle, the lenses are slightly yellow visually, and an image displayed through the blue-light lenses is often yellow, which has a great adverse effect on the visual effect of the image, for example: the white pattern can become faint yellow or yellow after penetrating through the blue-light-proof lens, thereby influencing the visual experience and being unfriendly to a family driving.
Disclosure of Invention
In order to solve the technical problem, the invention provides a blue light-resistant tawny lens with color fidelity.
The specific scheme is as follows:
the invention provides a blue light-resistant tawny lens with color fidelity, which meets the following conditions:
further, the color coordinates of the overall transmission spectrum of the blue-resistant tawny lens are within the range of (0.419, 0.395).
The invention also provides blue light-resistant tawny glasses with color fidelity, which comprise the blue light-resistant tawny glasses with color fidelity.
Has the advantages that:
the product of the invention effectively filters blue light, and the color coordinate of the transmission spectrum in the visible light wave band of 400nm-760nm is close to the color coordinate value of the central white point, so that the blue light-proof tawny lens has the effect of color fidelity.
Drawings

And (3) performance testing: the performance of the blue-light-proof dark brown lens prepared by the invention is tested.
Performance test standard:
according to the standards of various countries/regions for sunglasses: the following performance tests are carried out on the blue-light-proof dark-brown lens prepared by the invention according to China industry standard QB 2457-1999, European Standard ENISO 12312-1:2013 (A1: 2015), Australia Standard AS/NZS 1067:2003 (A1: 2009) and Australia Standard AS/NZS 1067.1:2016, wherein the test standards are shown in Table 1:
TABLE 1 Sunglasses Performance Standard List
And (3) performance test results:
the corresponding visual attenuation coefficients recognized by the signal lamp of the invention are as follows: q, Red (Red light) is larger than or equal to 2.25, Q, Yellow (Yellow light) is larger than or equal to 0.79, Q, Green (Green light) is larger than or equal to 0.98, Q, Blue (Blue light) is larger than or equal to 0.70, and the standard of various countries for the sunglasses is met.
The color coordinates of the central white point of D65 are (0.333 ), the color coordinates of the transmission spectrum of the product in the visible light wave band of 400nm-760nm are close to the color coordinates of the central white point, and the test results show that the blue light-proof tawny lens has the effect of color fidelity.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
