1.What is the cause of fogging? There are two reasons for the fogging: one is the liquefied phenomenon caused by the hot gas in the lens meeting the cold lens; The second is the evaporation of moisture on the surface of the skin sealed by the glasses and condensation of gas on the lens, which is also the main reason that the spray reagent does not work. An anti-fog glasses designed on the principle of electromagnet (see picture) is controlled by an electronic timing button that can adjust the frequency of demisting and the demisting strip is controlled by electromagnet. It can be used for swimming, skiing, mountaineering, diving, medical care (the anti-fogging problem of eye mask during SARS brought a lot of inconvenience to medical workers), labor protection, scientific research and biochemistry, helmet, space suit, optical instruments and meters, etc.
4. Coating Choice?
As anti-fog blue cut lens, super hydrophobic coating is the only coating choice for it. Super hydrophobic coating also name crazil coating, can make the lenses waterproof, antistatic, anti slip and oil resistance. Generally speaking , super hydrophobic coating can exist 6~12 months.
