Headgear with translucent visor brim

Abstract

Some embodiments provide a visor brim including a visor brim body and an optical filter configured to attenuate visible light in certain spectral bands. At least some of the spectral bands can include spectral features that tend to substantially increase the colorfulness, clarity, and/or vividness of a scene. In certain embodiments, headgear incorporates an optical filter that enhances chroma within one or more spectral bands. In some embodiments, a wearer of the headgear can perceive the increase in chroma when viewing at least certain types of scenes. In some embodiments, a wearer can combine chroma-enhancing headgear and chroma-enhancing eyewear to view complementary chroma enhancement.

What is claimed is: 
     
         1 . A visor brim for headgear, comprising:
 a brim body comprising a translucent optical filter,
 wherein the optical filter has a spectral profile that selectively attenuates ultraviolet radiation and selectively attenuates visible light in one or more spectral bands that increase a chroma value of the environment viewed through the visor brim, 
 wherein the chroma value is a C* attribute of a CIE L*C*h* color space, and 
 wherein the increase in chroma value comprises an increase compared to a neutral filter that uniformly attenuates a same average percentage of light as the optical filter. 
   
     
     
         2 . The visor brim of  claim 1 , wherein the visor brim comprises an optically transparent material. 
     
     
         3 . The visor brim of  claim 1 , wherein a portion of the visor brim is opaque and a remaining portion is translucent. 
     
     
         4 . The visor brim of  claim 1 , wherein the visor brim includes a gradient of tinting. 
     
     
         5 . The visor brim of  claim 1 , wherein the visor brim includes distinct portions of separate tints. 
     
     
         6 . The visor brim of  claim 1 , wherein the visor brim is made of polycarbonate. 
     
     
         7 . The visor brim of  claim 1 , wherein the visor brim has a marginal optical grade finish. 
     
     
         8 . The visor brim of  claim 1 , wherein the visor brim has a semi-optical grade finish. 
     
     
         9 . The visor brim of  claim 1 , wherein the visor brim has an optical grade finish. 
     
     
         10 . The visor brim of  claim 1 , wherein the optical filter comprises one or more organic dyes. 
     
     
         11 . The visor brim of  claim 1 , wherein the visor brim is adjustable. 
     
     
         12 . The visor brim of  claim 1 , further comprising one or more fastening locations configured for attachment to the headgear. 
     
     
         13 . The visor brim of  claim 1 , attached to headgear for a non-motorized sport. 
     
     
         14 . The visor brim of  claim 13 , attached to headgear for cycling. 
     
     
         15 . The visor brim of  claim 13 , attached to headgear for baseball. 
     
     
         16 . The visor brim of  claim 13 , attached to headgear for snow sports. 
     
     
         17 . The visor brim of  claim 13 , attached to headgear for water sports. 
     
     
         18 . The visor brim of  claim 1 , attached to headgear for a motorized sport. 
     
     
         19 . The visor brim of  claim 18 , attached to headgear for motocross. 
     
     
         20 . The visor brim of  claim 18 , attached to headgear for snowmobiling. 
     
     
         21 . A chroma enhancement system, comprising:
 the visor brim of  claim 1 ; and   an eyewear comprising a lens, the lens comprising an optical filter having a spectral profile that selectively attenuates visible light in one or more spectral bands that increase a chroma value of the environment viewed through the lens, wherein the one or more spectral bands of the optical filter of the lens are complementary to the one or more spectral bands of the optical filter of the brim body.
