Abstract: Embodiments of the disclosure relate to the use of dyes that impart localized regions of reduced transmittance across specific wavelength ranges. The inclusion of transmittance-attenuating dyes into a lens provides enhanced color contrast by tuning the spectrum of visible light transmission through the lens.

Abstract: The optical articles disclosed herein render polarized glare in a certain tunable color that is visually more perceptive than a regular tinted lens or a regular polarized lens. Optical articles, including sunglass lenses, that are configured to color plane-polarized light transmitted through the lens will draw the wearer's attention and help identify the contours or dangers on surfaces in the wearer's field of vision.

Abstract: Disclosed are methods for preparing partially polarized optical articles. A polarizing element is used to cover at least a portion of the front surface of an optical article to form a polarizing zone and a non-polarizing zone on the optical article. The optical article is then tinted to produce a gradual color transition between the polarizing zone and non-polarizing zone of the optical article.
