Optical wavefronts and the eye: implications to vision and diagnosis

The cornea and the crystalline lens form the image on the retina of the human eye. Tilt and decentration of the components and the angle of the fovea (area of most acute vision) from the optical axis also contribute. The resulting image quality on the retina is influenced by diffraction through the circular pupil of the eye, by the scattering of light, by chromatic aberration and by the monochromatic aberrations of the system. In this presentation, we will concentrate on the monochromatic wavefront aberrations of the eye, their measurement, and their influence on vision and ophthalmic diagnosis.
