摘要： 目的 探讨25岁和60岁亚洲和欧洲人种女性面部形态学差异对眼部光暴露水平的影响，为不同年龄人群眼部光损伤防护提供依据。方法 采用FaceGen软件构建25岁和60岁亚洲和欧洲人种女性3D面部形态学模型，在3ds Max软件中进行日光暴露模拟，提取左眼瞳孔部位灰度值作为光暴露水平。结果 眉弓及眉间部位对进入眼部光线的遮挡作用随太阳高度角的增高而增大；欧洲人种女性60岁模型眼部日光暴露模拟灰度值大于25岁模型且差异较大，而亚洲人种女性25岁和60岁模型之间眼部日光暴露模拟灰度值差异较小。结论 面部形态学差异的影响可导致老年人眼部光暴露危险性大于年轻人，且亚洲人种眼部光暴露危险性大于欧洲人种。

Abstract: Objective To investigate the effects of differences in facial morphological between 25-year-old and 60-year-old females of Asian and European descent on ocular light exposure and to provide evidence on light damage protection in the eyes of individuals of different ages. Methods The FaceGen software was used to construct 3D facial morphological models of 25-year-old and 60-year-old females from Asia and Europe. Sun exposure simulation was performed by the 3ds Max software,and the gray value of the pupil of the left eye was extracted as light exposure. Results The blocking effect of the superciliary arch and glabella on ocular light exposure increased with the increase in the solar elevation angle. The simulated gray value of ocular light exposure in the 60-year-old model of European females was greater than that in the 25-year-old model of European;while the difference between the 60-year-old model and the 25-year-old model of Asian females was not significant. Conclusion Owing to differences in facial morphology,the risk of ocular light exposure is greater in the elderly than in the young. The risk of ocular light exposure is also greater in Asians than in Europeans.
