Super-hydrophilic anti-fog optical lens and production method thereof

The invention discloses a super-hydrophilic anti-fog optical lens and a production method thereof. The super-hydrophilic anti-fog optical lens comprises a lens body, an anti-reflection layer is formed on the surface of the lens body, and a super-hydrophilic anti-fog layer is formed on the side, away from the lens body, of the anti-reflection layer; wherein the super-hydrophilic anti-fog layer comprises a hydrophilic group and an adhesion group. According to the super-hydrophilic anti-fog layer, water drops can be quickly spread on the surface of the lens at an ultra-small water drop angle (less than 10 degrees) to form an ultra-thin and uniform water film, so that the anti-fog characteristic of the optical lens is effectively improved while the light transmission performance of the surface of the lens is maintained, the applicability of optical image sensors such as cameras and laser radars is improved, and the application prospect is wide. And the use scenes of automatic driving, auxiliary driving and the li
