Natural dark brown safety glasses

Abstract

The present invention discloses natural dark brown safety glasses, and particularly relates to industrial protective safety glasses with natural dark brown colors. The natural dark brown safety glasses of the present invention are prepared by the following steps that: each 100,000 parts of polycarbonate (PC) is added with 5.459 parts of BK2 toner, 4.55 parts of 8150 toner, 1.582 parts of 8315 toner, 2.706 parts of H3B toner, 1.338 parts of yellow 3G toner, and 0.397 parts of blue L6385 toner, and a mixing treatment is performed. The natural dark brown safety glasses of the present invention are in line with a wavelength range of 400-700 NM, interval requirements on the upper limit and the lower limit of a chromaticity limit coordinate, and international standards, can be applied in the field of industrial safety glasses, and have characteristics of comfortable wear, safety, reliability and the like.

Description

technical field [0001] The invention discloses a natural brown safety lens, belongs to the technical field of spectacle lens manufacturing according to the International Patent Classification (IPC), and in particular relates to industrial protective safety glasses with natural brown color. Background technique [0002] Visible light is the part of the electromagnetic spectrum that can be perceived by the human eye. The wavelength of electromagnetic waves that can be perceived by ordinary human eyes is about 380 to 780 nanometers, and the visible colors corresponding to the wavelength of more than 700 nanometers to 400 nanometers are red, orange, yellow, and green. , indigo, and purple, among which red, green, and blue are called the three primary colors of visible light. [0003] Relevant practitioners in the field of industrial protection must wear brown protective glasses in order to carry out effective protection. The current brown lenses have large deviations and cannot ...

AI Technical Summary

Problems solved by technology

[0003] Relevant practitioners in the field of industrial protection must wear brown protective glasses to provide effective protection. The current brown lenses have large deviations and cannot meet the requirements of natural brown. The industry testing standards for brown lenses mainly meet the (400-700NM) band Interval, the interval requirements for the upper and lower limits of the chromaticity limit coordinates, however, the current brown lenses can not meet the above requirements of the chromaticity limit coordinates
