Impact of chromatic and higher-order aberrations of human eyes on vision based on special eye models

In the eye model involving the angle formed by visual and optical axis, an achromatic element eliminating longitudinal chromatic aberration (LCA) only while maintaining transverse chromatic aberration (TCA) is designed and the eye model of TCA-only is constructed. Furthermore, the actual data of human eye's higher-order aberrations are introduced into the eye model along visual axis to investigate the interaction between chromatic and higher-order aberrations. Three kinds of individual eye models are constructed to investigate the impact of higher-order aberrations, chromatic aberration (LCA+TCA), LCA and TCA on vision under the photopic condition, as well as their interactions. The results show that for most of the eyes the impact of chromatic aberration on vision is far greater than that of higher-order aberrations and the presence of chromatic aberration further reduces the impact of higher-order aberrations. Among the impact of chromatic aberration on vision, LCA is a dominant factor, and the impact of TCA can be ignored for most of the eyes. ©, 2014, Chinese Optical Society. All right reserved.
