technical field

The utility model belongs to the field of compound lenses, in particular to an anti-infrared compound lens.

Background technique

Existing goggles and face shields are mostly color mirrors or color-changing mirrors. Chromatic mirrors are made by incorporating a small amount of rare metal oxides into glass to produce various colors. The chromatic mirror is monochromatic and belongs to the absorption type lens. The light wave entering the chromatic mirror glass sheet will produce an electromagnetic effect, which will cause the glass lens to heat up and generate secondary radiation into the eyeball. The eyeball under monochromatic light stimulation is easy to cause fatigue of the optic nerve and eye tissue, and long-term wear will cause physiological lesions. The chromatic mirror is due to the shading effect of silver chloride folded out of silver particles under strong light. The role of such lenses is to prevent strong visible light from entering the eyes, and has a certain protective effect. Spectral tests show that such lenses have poor protection against ultraviolet and infrared rays. A type of cobalt blue lens currently worn by steel workers, this color lens containing cobalt ions is also less effective in protecting against ultraviolet rays and infrared rays.
