Abstract:	摘要： A biometry-based human eye model was developed by using the empirical anatomic and optical data of ocular parameters. The gradient refractive index of the crystalline lens was modeled by concentric conicoid isoindical surfaces and was adaptive to accommodation and age. The chromatic dispersion of ocular media was described by Cauchy equations. The intraocular scattering model was composed of volumetric Mie scattering in the cornea and the crystalline lens, and a diffusive-surface model at the retina fundus. The retina was regarded as a Lambertian surface and was assigned its corresponding reflectance at each wavelength. The optical performance of the eye model was evaluated in CodeV and ASAP and presented by the modulation transfer functions at single and multiple wavelengths. The chromatic optical powers obtained from this model resembled that of the average physiological eyes. The scattering property was assessed by means of glare veiling luminance and compared with the CIE general disability glare equation. By replacing the transparent lens with a cataractous lens, the disability glare curve of cataracts was generated to compare with the normal disability glare curve. This model has high potential for investigating visual performance in ordinary lighting and display conditions and under the influence of glare sources. 其他題名： J Biomed Opt 出版者： United States 出版日期： 2012-07-01 出處： Journal of Biomedical Optics, 2012-07, Vol.17 (7), p.750091-1-075009-11 版權： 2012 Society of Photo-Optical Instrumentation Engineers 識別號： ISSN: 1083-3668 識別號： ISSN: 1560-2281 識別號： EISSN: 1560-2281 識別號： DOI: 10.1117/1.JBO.17.7.075009 識別號： PMID: 22894481 識別號： CODEN: JBOPFO
