Heat absorption type anti-fog lens and preparation process thereof

The invention relates to a heat absorption type anti-fog lens and a preparation process thereof, and belongs to the technical field of lenses, the anti-fog lens contains a heat absorbent and an organic solvent, and the heat absorbent is dispersed in the organic solvent; the heat absorbent is one or a combination of more than two of indium tin oxide, tin antimony oxide and cesium tungsten oxide, and the organic solvent is a single solvent or a mixed solvent with a boiling point lower than 150 DEG C. According to the heat absorption type anti-fog lens and the preparation technology thereof, the heat absorption agent and the resin for the lens are mixed to prepare the heat absorption type anti-fog lens, the surface temperature of the anti-fog lens is increased through the heat absorption agent, the temperature difference between the anti-fog lens and the environment is reduced, and the long-term anti-fog effect is achieved; the preparation process of the anti-fog lens is simple and suitable for large-scale produ
