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.
Claims14
An optical article configured to color plane-polarized light transmitted through the optical article, the optical article having a color (A) and comprising:
- an optical article base material;
- a polarizing layer having a first color tint of color (B);
- and
- a second color tint of color (C);
- wherein:
- the difference in polarizing efficiency (ΔPE(λ)) of light transmitted through the optical article is at least 30% between a first visible wavelength and a second different visible wavelength;
- the overall PE of the optical article is less than 90%;
- and
- the color difference (ΔE) between the optical article color (A) and the first color tint color (B) is greater than 2.
