OPTICAL ELEMENT AND METHOD OF MANUFACTURING SUCH AN OPTICAL ELEMENT

摘要

The invention relates to an optical element comprising a substrate which is provided with a transparent layer comprising an organic polymer network and one or more photochromic compounds, in which the transmission of the optical element in the visible wavelength range changes in response to a variation of incident light, while the transparent layer comprising photochromic compounds is provided with a protective coating on the side remote from the substrate side.
