The optical lens (10) has a lens element (12) made of plastic transparent in a visible spectral range and comprising a coating (14) having multiple layers (15). The multiple layers have a high-refracting layer (18). A hard coating layer (20) adjoined to the lens element is formed. A super-hydrophobic layer (16) closes the coating. The coating commonly has a thickness of more than 380 nanometers and in case of one high-refracting layer the high-refracting layer has a thickness of less than 40 nanometers.
