Abstract: This invention relates to light filters employing redox compounds that are substantially light-transmitting in their oxidized state and capable of forming a stable colored free radical upon the addition of electrons. The colored free radical formed in response to the flow of electric current renders the device light-absorbing. To restore the original lighttransmitting properties, the colored free radical may be readily reoxidized, for example, by reversing the direction of current flow.

Abstract: Polarized prescription spectacles are furnished with lenses ground and polished from pleochroic crystals. Pleochroic crystals are readily polished to the contours required on ophthalmic lenses. The crystal is oriented with its principal absorption axis horizontal and at right angles to the lens axis. Sunglasses can be fitted with certain pleochroic crystals to reduce solar intensity for the wearer as well as glare from terrestrial sources.
