We investigated the claims of EnChroma that their notch filters aid chromatic discrimination in color-vision deficiencies (CVD). Few research studies have addressed these claims and reports are still inconclusive, mainly due to small sample sizes. We here add to previous research finding little evidence to support the benefits of EnChroma lenses. Comparing the performance of 86 well-categorized CVD observers and 24 controls on two clinical tests we report no overall improvement when EnChroma lenses were worn. In line with previous studies, our results imply an improvement in discrimination for some colors while worsening discrimination for others. A model was constructed computing discrimination changes for different groups of ideal observers corroborating our behavioral outcomes. Taken together, our results do not support the use of EnChroma notch filters for the improvement of color discrimination in CVD.
我们调查了 EnChroma 的声称,即他们的缺口滤波器有助于改善色觉缺陷(CVD)中的色觉辨别能力。很少有研究关注这些说法,报告仍然没有定论,主要是由于样本量小。我们在这里增加了之前的研究结果,几乎没有证据支持 EnChroma 镜片的好处。在比较了 86 名分类良好的 CVD 观察者和 24 名对照者在两项临床测试中的表现后,我们报告说当佩戴 EnChroma 镜片时,整体表现没有提高。与之前的研究一致,我们的结果表明,对于某些颜色的辨别能力有所提高,而对于其他颜色的辨别能力则有所下降。我们构建了一个模型,计算了不同理想观察者群体的辨别力变化,证实了我们的行为结果。综上所述,我们的结果不支持使用 EnChroma 缺口滤波器来改善 CVD 中的色觉辨别能力。
