Background
Most of the existing goggles and masks are colored glasses or color-changing glasses. The chromatic mirror is formed by doping a small amount of rare metal oxide into glass to generate various colors. The chromatic mirror has monochromaticity and belongs to an absorption lens, and light waves entering a glass sheet of the chromatic mirror can generate electromagnetic effect, so that the glass lens generates heat and generates secondary radiation to enter the eyeball. Under the stimulation of monochromatic light, eyeballs are easy to cause fatigue of optic nerves and eye tissues, and physiological pathological changes can be generated after long-term wearing. The color-changing lens has shading effect because silver chloride is folded out of silver particles under strong light. The lens has the function of preventing strong visible light from entering eyes, and has a certain protective effect. The spectrum test shows that the protective efficiency of the lens to ultraviolet rays and infrared rays is very poor. The cobalt blue lens worn by steel-smelting workers at present has poor ultraviolet and infrared protection effect.
