Abstract:
The present invention relates to an optical lens having a lens element produced of plastic, more particularly of plastic which is transparent in a visible spectral range, and having a coating comprising a plurality of layers, the plurality of layers comprising at least one high-refractive-index layer. Furthermore, a hardcoat layer is formed adjacent to the lens element, and a superhydrophobic layer concludes the coating in opposition to the lens element. The at least one high-refractive-index layer has a thickness of less than 40 nm, and the coating overall has a thickness of more than about 380 nm.
