What is the difference between safety glasses and goggles?
Protective glasses refer to "safety protective glasses", which are glasses that play a special role, such as surgical glasses for hospitals, welding glasses for electric welding, laser protective glasses for laser engraving, etc.; goggles are a kind of filter The light mirror can change the transmitted light intensity and spectrum to avoid damage to the eyes caused by radiated light.
There are many types of protective glasses, such as dust-proof glasses, impact-proof glasses, chemical-proof glasses and optical-radiation-proof glasses, etc., and the glasses required by different occasions are also different. Due to the different protective effects, the characteristics of the lenses are also significantly different. Those who need to wear protective glasses to work should understand the harmful factors in their working environment, wear appropriate safety protective glasses, and do not wear them indiscriminately.
Goggles can absorb certain wavelengths of light and let other wavelengths of light pass through, so most goggles will show a certain color, and the color presented is the color of the transmitted light. When this kind of lens is manufactured, a part of metal oxides, such as iron, cobalt, chromium, strontium, nickel, manganese and some rare earth metal oxides such as neodymium and neodymium, are added to the general optical glass formula to achieve the effect of absorbing light. .
