眼睛的单色光学像差会降低视网膜图像质量。出生后发育过程中的任何显着畸变都可能导致婴儿视觉表现不成熟，并为控制眼睛生长提供信号。使用类似成人的婴儿眼睛模型，将 5 至 7 周大的人类婴儿眼睛的像差与成年受试者的像差进行比较，该模型考虑了眼睛和瞳孔大小的差异。使用 COAS Shack-Hartmann 波前传感器收集数据。结果表明，5 至 7 周大的眼睛的高阶像差比该年龄的类似成人的婴儿眼睛的预测值高不到 2 倍。这些数据是在婴儿视觉表现和可用于控制眼睛生长的信号的背景下讨论的。
The monochromatic optical aberrations of the eye degrade retinal image quality. Any significant aberrations during postnatal development could contribute to infants' immature visual performance and provide signals for the control of eye growth. Aberrations of human infant eyes from 5 to 7 weeks old were compared with those of adult subjects using a model of an adultlike infant eye that accounted for differences in both eye and pupil size. Data were collected using the COAS Shack-Hartmann wavefront sensor. The results demonstrate that the higher order aberrations of the 5-to-7-week-old eye are less than a factor of 2 greater than predicted for an adultlike infant eye of this age. The data are discussed in the context of infants' visual performance and the signals available for controlling growth of the eye.
