Embodiment Construction

[0014] An anti-blue light brown polarized sun lens disclosed by the present invention is composed of a filter and a polarizing film. The filter is made of polycarbonate PC and 7308 toner, 8415B toner, and 8416 toner produced by Bayer Company of Germany. , 8410 toner mixed, wherein, for every 100 kg polycarbonate PC add 2.21 grams of 7308 toner, 10.57 grams of 8415B toner, 7.70 grams of 8416 toner and 0.86 grams of 8410 toner.

[0015] The lens formed by the invention is tested by a professional international standard spectrum tester for transmittance spectrum testing. The brown polarized lens meets the standards of the three countries, namely the American standard ANSIZ80.3, 2001, the European standard EN1836, 2005 (A1, 2007), and the Australian standard (AN / NZS 1067, 2003), and when the average wavelength of the light wave is 380-500 nanometers and the light wave is 470 nanometers, the transmittance is lower than 5%, effectively blocking the entry of blue light.

Abstract

The invention discloses a blue light resistant tawny polarized sunglasses lens, which is formed by combining an optical filter and a polarizing film, wherein the optical filter is made by mixing PC, 7308 color powder, 8416 color powder, 8415 color powder and 8410 color powder according to a principle that each 100 kilograms of PC is added with 2.21 grams of 7308 color powder, 7.70 grams of 8416 color powder, 10.57 grams of 8415 color powder and 0.86 grams of 8410 color powder. Besides having a tawny color, the lens can effectively prevent light rays with a wave length ranging from 380 to 500 nanometers from penetrating and therefore can reduce the damages of the blue light to eyes and prevent eye diseases such cataract and diseases in retinal macular area. In addition, the combined polarizing film can effectively prevent glare and make the vision field clear. The lens is particularly suitable for people who receive a cataract surgery, have a history of macular degenerative disease, are being taken care of after laser surgery, have pseudomyopia, have frequent outdoor activities, live in areas with high sunlight, use computer for a long term or the like.

Description

technical field [0001] The invention relates to a lens, in particular to an anti-blue light brown polarized sun lens. Background technique [0002] At present, many places (such as some test instruments, etc.) have requirements for light. Some places do not allow light of a certain band to enter, and some places only allow light of a certain band to enter. Therefore, some people in the industry have specially developed Various light-transmitting materials that can cut off (or filter) a certain wavelength, such as plastic filter materials, specific products include UV cut-off filters (can block ultraviolet rays from passing through), blue light cut-off filters (can block blue light from passing through) ... However, these materials and their products are currently mainly used in research experiments, and the application in eyewear products is still a blank. [0003] Experts pointed out that strong ultraviolet rays can easily cause damage to the eyes. Blue light can accelerat...
