This study first confirmed the repeatability of this setup by repeating the experimental process for 4 times. Then the experiment was performed to measure the straylight parameters from 7 subjects in the following conditions: four glare source wavelengths, 450, 555, 610 and 670 nm, and six glare angles, 5, 10, 15, 20, 30 and 45 degrees. The result showed the stronger scatter at short wavelength of glare, the decay with the increment of the wavelength value, and finally a boost at long wavelength value. The explanation for the results in the discussion revealed a coupled model of Rayleigh scatter effect, Mie scatter effect, fundus reflection and aging effect. At last, the comparison between the results with well-known disability glare equation showed a good match with the CIE disability glare equation. en_US DC.subject 眼內散射 zh_TW DC.subject Intraocular Scattering en_US DC.title 人眼眼內散射與波長相依性之研究 zh_TW dc.language.iso zh-TW zh-TW DC.title The study of wavelength-dependent ocular scatter in human eye en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
