With the development of science and technology, the strength of eyes used by people is increased, the protection consciousness of the glasses is stronger and stronger, and the glasses such as the myopia glasses, the sunglasses, the diving goggles and the like are also more and more widely applied to the daily life of people. The glasses for correcting the vision comprise four types of glasses for myopia, hyperopia, presbyopia and astigmatic. From the function of the lens, the lens can adjust the brightness entering the glasses and protect the eyesight; the spectacle frame and the spectacle frame play a role of a bracket and also have the effects of beauty treatment and decoration. The wearing of glasses has certain protection and decoration effects, but sometimes brings inconvenience. When a person wearing the glasses enters a high-temperature environment from a low-temperature environment or in rainy and snowy weather, water molecules in the air are liquefied and attached to the outer surface of the lens, water mist is easily generated, the sight of the person is blocked, and inconvenience is caused.

The existing anti-fogging means generally uses anti-fogging spray to treat or paste an anti-fogging film on lenses, but the method is extremely inconvenient and can cause certain damage to the lenses, and the anti-fogging effect of the glasses lenses is not obvious or even fails after long-time use. In another electric heating type anti-fogging glass lens, water is evaporated by electric heating, but water stains are left on the surface of the lens.
