FINITE PRESBYOPIC SCHEMATIC MODEL EYE

摘要

PURPOSE: A finite presbyopic schematic model eye is provided to remove the refraction abnormality of coma aberration, spherical aberration, and secondary astigmatism. CONSTITUTION: A cornea(10) forms the front face and a rear face of aspheric side and has a Zernike polynomial side. A lens(20) is located in rear part of the cornea is comprised of two cells. A retina(40) is located in rear part of a crystalline lens and use the Stiles-Crawford effective function of a photoreceptor cell. A pupil(30) is located in front of the crystalline lens and has eccentricity to node side.
