Abstract
The present invention provides a method of forming a nano-pattern on a surface of a lens, which comprises steps of: (i) filling a conductive material in an space between a lens and a substrate; (ii) applying a first coating solution to the surface of the lens filled with the conductive material by to a wet process; (iii) forming a nano-pattern on the surface of the lens on which the first coating solution is applied by performing a reactive ion etching process; and (iv) removing the first coating solution remaining on the lens surface and the conductive material filling in the space between the lens and the substrate. The lens of the present invention is a functional lens with low reflectance, high transmittance and super water-repellency owing to a functional coating layer, thereby replacing the conventional lens on which an anti-reflective coating is formed. Thus, the lens manufactured by the method of the present invention may be widely used in the fields where low reflectance and high transmittance are requires, such as a rear camera lens for vehicles.
