This study aimed to examine the effect of the cut ratio on contrast sensitivity by modifying the cut rate of the wavelength-selective cut lens at approximately 585 nm. Contrast sensitivity when wearing a selective yellow-cut lens with 50%, and 70% optical cut rate was higher than that without a yellow-cut lens; thus, these lenses could improve contrast sensitivity. Selective yellow-cut lenses of approximately 50% optical cut rate could improve contrast sensitivity in healthy individuals. Therefore, wavelength-controlled lenses can contribute to the improvement of the contrast sensitivity.

选择性黄切镜片切割比对对比敏感度的影响

本研究旨在通过修改波长选择性切割透镜在大约 585 nm 处的切割率来检查切割比对对比敏感度的影响。配戴50%选择性黄切镜片时的对比敏感度，70%光学切角率高于未戴黄切镜片者；因此，这些镜头可以提高对比敏感度。大约 50% 光学切割率的选择性黄切镜片可以提高健康个体的对比敏感度。因此，波长控制透镜有助于提高对比度灵敏度。
