    Abstract: An optical filter including a polymeric multilayer optical film is provided. The optical film has a reflection band having a reflection band edge that is, independent of location, one of a short wavelength band edge at a short wavelength side of the reflection band and a long wavelength band edge at a long wavelength side of the reflection band. The reflection band edge has a normal incidence reflection band edge wavelength that varies with location and that is a first wavelength at a first location and a second wavelength at a second location different from the first location. The first wavelength may be higher than the second wavelength by at least 2 percent.

    Abstract: Certain filters have been found to enhance color discrimination for individuals with color vision deficiency (CVD), aka color-blind individuals. The filters generally include a multilayer optical film with a strong, narrow reflection band in part of the green region of the visible spectrum. The film has an average internal transmission from 420-680 nm of at least 50%, 60%, or 70%, and an average internal transmission≤10%, 5%, 2%, or 1% over a 10 nm wide range that includes 550 nm associated with a reflection band having a width (FWHM) of 60 nm or 50 nm or less. The filter may include a magenta layer disposed on a viewer side of the multilayer optical film to reduce glare, the magenta layer selectively absorbing green light. The magenta layer combined with the multilayer optical film may provide a rejection band whose width (FWHM) is 60 nm or less.

    Abstract translation: 已经发现某些过滤器可以增强色觉缺陷（CVD）的个体的色差，也就是色盲个体。 滤光片通常包括在可见光谱的绿色区域的一部分中具有强的窄反射带的多层光学膜。 该薄膜在10nm宽范围内具有420-680nm的平均内部透射率至少为50％，60％或70％，平均内透射率为10％，5％，2％或1％ 其包括与具有60nm或50nm以下的宽度（FWHM）的反射带相关联的550nm。 滤光器可以包括设置在多层光学膜的观察者侧的品红色层以减少眩光，品红色层选择性地吸收绿色光。 与多层光学膜结合的品红色层可以提供宽度（FWHM）为60nm以下的抑制带。
