Goggles: the role and efficacy of goggles
Goggles can prevent the radiation source light from causing harm to the eyes, and to put it bluntly, goggles are a kind of filter. There are two types, one is absorption heat pump, one is double beam, and the previous one is used more. This kind of light source that can digest and absorb some light wavelengths and allow other light wavelengths to pass through, thus showing an inevitable hue, and the hue displayed is the through-light hue.

When making such spectacle lenses, a part of hydroxides such as iron, cobalt, chromium, strontium, nickel, manganese and some metal oxides such as neodymium are added to the general optical lenses. This hydroxide enables laminated glass to selectively digest and absorb radio waves in certain stock bands in the light source, such as cerium and compounds that can digest and absorb ultraviolet light.
The use of such glass lenses can reduce the amount of some light wavelengths passing through the spectacle lens and avoid causing harm to the eyes. Goggles are mainly divided into two categories, one is an absorption heat pump, and the other is a double beam.
Absorption heat pump: absorption heat pump filter, is the use of glasses for some light wavelength light digestion and absorption, in order to reduce the light intensity into the eyeball. The absorption heat pump filter includes eye protection glasses for shading, gas cutting, eye protection glasses for electric arc, dark blue eye protection glasses, dark red laminated glass, laser goggles and microwave heating goggles.
Double beam: absorption heat pump filter, is the lens digestion and absorption of some light source, into the heat release, especially infrared induction and other longer wave light source, because of the accumulation of heat, so that the eyes feel. If the reflective surface filter is used, this problem can be solved very well. When the absorption heat pump and double beam are applied together, that is, a layer of high reflective film is plated on the colored plate spectacle lens to make the actual filtering effect stronger, such as low-temperature plasma cutting and other practical operation staff wearing it can be solved by this method.
What are the functions and actual effects of goggles? In our daily life, we will all use to obtain goggles, but when we choose, we should make decisions about the type of goggles and our own conditions in our own work. We will see, choose, match, and understand maintenance and cleaning together.
