The purpose of the present study was to objectively quantify the spectral transmittance of the eyelid. Reported here are data acquired using a technique that was developed to provide practical and accurate measurements of eyelid transmittance across the visible portion of the electromagnetic spectrum. The empirical data were analyzed in terms of the absorption and scattering characteristics of the constituents of skin to develop a method for predicting eyelid transmission. Results showed that the eyelid has a much higher optical density at short wavelengths than previously published. The mean ± standard deviation (s.d.) optical density of the eyelid from 450 to 650 nm was 2.1 ± 0.3 with an optical density range among subjects of approximately 1.0. The study results indicate that skin pigmentation is poorly correlated with eyelid transmission; eyelid transmission is most affected by wavelength-independent macromolecules in the eyelid as well as its overall thickness.
本研究的目的是客观量化眼睑的光谱透过率。本文报道了一种技术获得的数据，该技术旨在提供对电磁光谱可见部分的眼睑透过率进行实用且准确的测量。根据皮肤成分的吸收和散射特性对经验数据进行了分析，以开发一种预测眼睑透过率的方法。结果表明，与之前发表的数据相比，眼睑在短波长处的光密度要高得多。从 450 到 650nm 的眼睑平均光密度±标准偏差（s.d.）为 2.1±0.3，受试者之间的光密度范围约为 1.0。研究结果表明，皮肤色素沉着与眼睑透过率相关性较差；眼睑透过率受眼睑中波长独立的大分子以及其整体厚度的影响最大。
