Four color-deficient observers and one normal trichromatic subject were evaluated with color vision and stereoacuity tests during 1 month of X-Chrom lens wear. For all color tests, performance of the normal subject was unaltered by X-Chrom lens wear. Color-deficient subjects demonstrated improved performance on the Ishihara pseudoisochromatic color plates, but either degraded performance or no change on the Farnsworth-Munsell 100-hue or Pickford-Nicolson red-green anomaloscope test. Three of the five subjects exhibited degraded stereoacuity in conjunction with X-Chrom lens wear. We conclude that the X-Chrom lens does not improve discrimination in color-deficient subjects and may alter stereopsis.
在佩戴X-Chrom镜片的1个月期间，对4名色觉缺陷观察者和1名正常三色视受试者进行了色觉和立体视敏度测试。对于所有颜色测试，正常受试者的表现并未因佩戴X-Chrom镜片而改变。色觉缺陷受试者在石原氏假等色板测试中表现有所改善，但在 Farnsworth-Munsell 100色调测试或Pickford-Nicolson红绿色异常视标测试中，要么表现下降，要么没有变化。五名受试者中有三名在佩戴X-Chrom镜片时立体视敏度下降。我们得出结论，X-Chrom镜片并不能改善色觉缺陷受试者的辨别能力，并且可能会改变立体视觉。
