What are the functions of goggles? Next, let's look at the introduction! Protective glasses are light filters that can change the transmission intensity and spectrum. To avoid eye damage caused by radiation, the effective and common method is to wear protective glasses.

The goggles can absorb light of some wavelengths and let light of other wavelengths pass through, so they all present a certain color, and the color presented is the color of light transmission. One is absorption type, the other is reflection type, the former is used more. Goggle is a kind of glasses that can avoid the damage to eyes caused by radiation light by changing the transmission light intensity and spectrum. This kind of glasses can be divided into two categories, one is absorption type, and the other is reflection type. The former is more used. This kind of glasses can absorb light of some wavelengths and let light of other wavelengths pass through, so they all present a certain color, and the color presented is the color of light transmission. Absorption filter refers to the absorption of certain wavelengths of light by lenses to reduce the intensity of light emitted into the eyes. Blue goggles; There are two kinds of glasses. One is to color the filament with iron oxide and cobalt oxide, which is purplish red. The other is to color the filament with copper oxide and manganese oxide, which is white. Eye protection glasses for electric welding. Ultraviolet light generated by electric welding will cause damage to cornea and conjunctiva tissue (28 nm light is severe) when it is exposed to the eyeball for a short time. The intense infrared ray produced is very easy to cause eye lens opacity. Welding goggles can well block the above infrared and ultraviolet rays.
