Abstract
A lens for eyeglasses includes a substrate and at least one carbon nanotube (CNT) film including a number of CNTs. The substrate includes a surface, or defines at least one cavity. The at least one CNT film is disposed on the surface of the substrate, or embedded in the at least one cavity of the substrate such that a part of light is absorbed by the CNTs of the CNT film.
