A broadband red filter placed over one eye will have the effect of improving the ability of certain color vision defectives to name colors correctly. A red-tinted contact lens will have the same effect; such a device is marketed under the name, the X-Chrom lens. In this article, the author examines the basic properties of color vision defects, explains the optical effect of the red filter, and reviews several studies which evaluate the effect of the X-Chrom lens. He concludes that while the lens may allow the wearer to achieve a better score on certain color vision tests, it does not actually correct color vision in the natural environment. Deleterious effects of wearing a red filter are also discussed. It is advised that patients wearing the X-Chrom lens be fully apprised of its limitations and of dangers that may be created by the associated visual distortions.
在一只眼睛上放置一个宽带红色滤光片，会提高某些患有色觉缺陷的人正确说出颜色的能力。红色隐形眼镜也会有同样的效果；有一种这样的产品以“X-Chrom镜片”的名称销售。在本文中，作者研究了色觉缺陷的基本特性，解释了红色滤光片的光学效果，并回顾了几项评估X-Chrom镜片效果的研究。他得出结论，虽然这种镜片可能会让佩戴者在某些色觉测试中获得更好的分数，但它并不能在自然环境中真正矫正色觉。文中还讨论了佩戴红色滤光片的有害影响。建议佩戴X-Chrom镜片的患者充分了解其局限性以及由相关视觉扭曲可能产生的危险。
