Anti-blue-light amber protection eyeglass

Abstract

The invention discloses an anti-blue-light amber protection eyeglass, and particularly relates to an anti-blue-light protection eyeglass in an amber color. The eyeglass is prepared by mixing the following components: 100 parts of polycarbonate (PC), 3.75 to 4.13 parts of BK2 color powder, 61.51 to 67.65 parts of 8150 color powder and 5.11 to 5.61 parts of red G-color powder. The eyeglass has a function of completely filtering and blocking blue visible light (380 to 500 nanometers), so that harm of the blue light to eyes is completely avoided; eye diseases such as retina macular region lesion can be prevented; and the anti-blue-light amber protection eyeglass is suitable for industrial production protection and working groups who work in a blue light environment with natural strong light and the like.

Description

technical field [0001] The invention discloses an anti-blue light amber protective lens, belongs to the technical field of spectacle lens manufacturing according to the International Patent Classification (IPC), and in particular relates to anti-blue light protective safety glasses with amber color. Background technique [0002] Experts pointed out that blue light is easy to cause damage to the eyes, especially it will accelerate the oxidation of cells in the macular area of ​​the retina. If the macular area is exposed to blue light for a long time, it will even damage the visual cells, which will increase the risk of macular degeneration in the eyes in old age. Common sources of blue light include modern industrial production light sources and natural strong light such as ultraviolet rays, which will cause harm to relevant production operators. It is necessary to filter and block blue light with a wavelength of 380-500NM of blue visible light. [0003] At present, many plac...

Problems solved by technology

However, the above-mentioned filtering, blocking or absorbing, and cutting off of visible light are mainly used in research experiments at present, especially the deep cut-off of visible light, which refers to the absorption of more than 99.9% of the light waves in the required waveband, and the light in the corresponding waveband passes through. The target rate is controlled below 0.1%, which is still blank in the application of eyewear products

[0004] Blue light is easy to damage the eyes and cause the risk of macular degeneration. At present, the only way to prevent blue light from harming eyesight is to choose a pair of functional anti-blue light lenses. Most of the sun lenses on the market can only resist sunlight. Ultraviolet light or infrared light cannot resist the blue light which has a strong penetrating power and can directly reach the macular area

Chinese document ZL201010153357.5 discloses an anti-blue light brown polarized sun lens. However, the lens prepared by the inventor according to the formula provided by the applicant cannot reach the blue light with a depth cut-off wavelength of 380-500nm, and the light transmittance of the corresponding wavelength band Above 20%
