This study aimed to explore the impact of three wavelength-cut (TWC) lenses, which allowed 75% luminance transmittance while blocking wavelengths < 420 nm, approximately 460 nm, and approximately 585 nm, on visual function and color perception, and aging interaction effect. This single-center study enrolled 30 participants into two groups including 15 young participants (age 21.4 ± 1.3 years) and 15 older participants (age 71.7 ± 1.7 years). We used TWC lenses and a neutral density (ND) filter to assess the wavelength-cut effects on visual acuity, contrast sensitivity, and cone contrast sensitivity. Visual acuity and contrast sensitivity were assessed under photopic (luminance 85–100 cd/m²) and mesopic conditions (luminance 0.8 cd/m²). Significant interactions between age and lens conditions were observed for contrast sensitivity under photopic conditions (Bonferroni corrected α = 0.025, F_(1,28) = 7.98, P = 0.01, η² = 0.003), suggesting that contrast sensitivity to white and black gratings is better with TWC lenses (75%) than with the ND filter in young participants (F_(1,28) = 7.25, P = 0.01, η² = 0.206). However, the lens condition did not affect visual acuity and had only a minimal effect on cone contrast sensitivity for each cone type. In conclusion, TWC lenses, despite their nearly colorless and transparent appearance, can selectively block specific wavelengths to improve contrast sensitivity, while minimally affecting color perception. However, since the effect size of these interactions is very small, the impact is limited, therefore glasses should be prescribed with caution for young individuals.

本研究旨在探讨三种波长截止 （TWC） 镜片的影响，它们允许 75% 的亮度透射率，同时阻挡波长 < 420 nm、约 460 nm 和大约 585 nm，对视觉功能和颜色感知以及衰老交互效应的影响。这项单中心研究将 30 名参与者分为两组，包括 15 名年轻参与者 （年龄 21.4 ± 1.3 岁） 和 15 名老年参与者 （年龄 71.7 ± 1.7 岁）。我们使用 TWC 镜片和中性密度 （ND） 滤光片来评估波长切割对视力、对比敏感度和视锥对比敏感度的影响。在明视 （亮度 85-100 cd/m²） 和中间视觉条件 （亮度 0.8 cd/m²） 下评估视力和对比敏感度。在明视条件下观察到年龄和晶状体条件之间对比敏感度的显着相互作用 （Bonferroni 校正 α = 0.025，F_（1,28） = 7.98，P = 0.01，η² = 0.003），表明在年轻参与者中，TWC 镜头对白色和黑色光栅的对比敏感度 （75%） 优于 ND 滤光片 （F_（1,28） = 7.25，P = 0.01，η²= 0.206）。然而，晶状体状况不会影响视力，并且对每种视锥细胞类型的视锥细胞对比敏感度的影响很小。总之，TWC 镜头尽管外观几乎无色透明，但可以选择性地阻挡特定波长以提高对比敏感度，同时将对色彩感知的影响降至最低。然而，由于这些相互作用的效应量非常小，影响有限，因此应谨慎为年轻人开眼镜。
