| 摘 要： | 利用Zemax软件建立了Navarro, Atchison和Zapata-Díaz三种年龄相关性人眼模型的光学系统,评估并比较了各模型眼在不同年龄及不同调节状态下的成像质量。模拟了入瞳直径分别为3 mm和5 mm时,各模型眼在年龄为20～60岁时的成像质量,以及Navarro和Zapata-Díaz模型眼在0.5～2 D范围内的调节。结果表明,三种模型眼的成像质量均随年龄的增长或者入瞳直径的增加而变差,Atchison模型眼在不同年龄下的成像质量更好,且较符合临床实际,Navarro模型眼在调节过程中具有更好的成像质量。研究结果可为视光学领域中年龄相关性人眼模型的选择提供参考。

| Abstract: | In this paper, we built the optical systems of three age-related human eye models, including the Navarro, the Atchison and the Zapata-Díaz models using the Zemax software, and analyzed the changes of image quality at different ages and different accommodation status. Simulations included retinal image quality evaluations at both 3 mm and 5 mm entrance pupil diameters (EPDs). Accommodation amplitudes ranging from 0.5 D to 2 D were measured in the Navarro and Zapata-Díaz models. Image quality worsens with age or EPD in all the age-related eye models. Besides of the good imaging quality, the Atchison model eye is also consistent with clinical results. Navarro model performs better during accommodation. The results of this study can be valuable for the eye model selection in the field of optometry. |
