Light filters using yellow melanin and melanin-like oligomers and photochromic dyes |
摘要 |
Light filters that use yellow melanin or melanin like materials prepared to have a yellow color and a melanin transmission spectrum in combination with a photochromic dye are disclosed. The yellow form of melanin has minimal impact on the perception of light intensity with transmission values greater than 80%. The combination allows for a single light filter suitable for both night driving and sunglass applications and which also preserve color perception.
