Light filters with wavelength-dependent transmission and in particular cut-off or step filters (steep dependence of transmission on wavelength) have a broad optical application and are relevant in ophthalmology. This article describes some physical and physiological principles of cut-off filters, discusses the physiological aspects of applications, specifically the not always relevant necessity of blue-reducing filters and the lack of efficacy of color filters with color vision deficiencies.
具有波长依赖性透射的滤光片,特别是截止滤光片或阶跃滤光片(透射率对波长的强烈依赖性)具有广泛的光学应用,并且在眼科领域也具有相关性。本文描述了截止滤光片的一些物理和生理原理,讨论了应用的生理方面,特别是减少蓝光滤光片并非总是必要的,以及有色觉缺陷者使用彩色滤光片的无效性。
