Ders Açıklama |
What is vision? Anatomy of the eye. Dissection. Average and range of sizes, shapes and indices of ocular components. Overview of optical modeling. Definition of visual acuity. Schematic eye models. Gullstrand-LeGrand and Helmholtz models. First-order properties. Locations of cardinal points. Definitions of near point, far point, myopia and hyperopia. Aspheric eye models.
