The change in pupil centration occurring as the human eye pupil dilates, both naturally in darkness and following the use of a mydriatic drug (cyclopentolate HCl, 1%), has been measured photographically. In both cases, changes in centration of up to 0.4 mm have been found. Using available ocular wavefront aberration data, modulation transfer curves have been derived for two eyes for centration changes of 0.2 mm. The importance of these changes in the formation of the retinal image, and hence on visual performance, is discussed.
通过摄影测量了人眼瞳孔在自然黑暗环境中以及使用散瞳药物（1%盐酸环喷托酯）后扩张时瞳孔中心位置的变化。在这两种情况下，均发现中心位置变化可达0.4毫米。利用现有的眼波前像差数据，针对两只眼睛推导出了中心位置变化0.2毫米时的调制传递曲线。讨论了这些变化在视网膜图像形成中以及因此对视觉性能的重要性。
