Abstract:
An optical element includes a first boundary layer and a second boundary layer. A solution is disposed between the first boundary layer and the second boundary layer. The solution includes liquid crystals co-mingled with oblong photochromic dye molecules. The photochromic dye molecules are matched to the liquid crystals to offset a decrease in absorption of the photochromic dye molecules in response to a temperature increase of the photochromic dye molecules.
