Anti fog transparent medical safety glasses

Safety glasses are a kind of filter that can change the transmitted light intensity and spectrum. The most effective and commonly used method to avoid damage to the eyes caused by radiant light is to wear safety glasses. This kind of glasses can absorb light of certain wavelengths and let other wavelengths of light pass through, so they all present a certain color, and the color presented is the color of the transmitted light.

When safety glasses are manufactured, a part of metal oxides, such as iron, diamond, chromium, strontium, nickel, manganese, and some rare earth metal oxides such as neodymium, are added to the general optical glass formulation. These metal oxides enable the glass to selectively absorb electromagnetic waves in a certain range of light.There are two types of safety glasses: absorptive and reflective. The former is the most used.
