  • A chromatic corrector with two refractive-diffractive hybrid elements is designed for a wide field-of-view of 14 to correct chromatic aberrations in human eyes. The performance of the corrector based on several optical criteria is compared with a chromatic corrector with single refractive-diffractive element. Results show that both correctors can correct for Longitudinal Chromatic Aberration(LCA). However, it is demonstrated that the chromatic corrector with a single element introduces serious eccentric Transverse Chromatic Aberration (TCA) that increases from 14.61 m to 81.4 m. This deteriorates the image quality at the edge field-of-view. On the chromatic corrector with two refractive-diffractive elements, both the LCA and the TCA can be corrected and the TCA is just 1.64 m. The designed chromatic corrector can be used to improve the retinal image quality and has potential applications in the design of visual instruments.
