Electro-optic lens having multiple responsive regions of a variable degree of light transmission, method of fabrication thereof and method of operation thereof

摘要

The present invention is directed to a lens having a variable light transmission in response to variations in incident light intensity. The lens is useful for providing eye protection from variations in ambient light intensity. The present invention is directed to shade devices having lenses which have a variable degree of light transmission which automatically changes in response to the intensity of incident light or at the selection of a user of the eye glasses.
