The model comprises an optical bench base, a light source assembly, a cornea assembly, an iris assembly, a lens assembly and a retina assembly, the optical bench base comprises a first base plate, a second base plate, a first guide rail and a second guide rail,the first and second base plate are separately provided with guide rail insertion holes, and the two ends of the first guide rail and the second guide rail are arranged between the first seat plate and the second seat plate in parallel in a penetrating mode through the guide rail insertion holes; and base sliding blocks of the light source assembly, the cornea assembly, the iris assembly, the crystalline lens assembly and the retina assembly are installed on the first guide rail and the second guide rail through a first sliding hole and a second sliding hole and can slide along the rails. Themodel can be used for demonstrating the optical function of human eyes and simulating the biological characteristic change of optical structures of the eyes, so that the influence of the optical structures on light refraction and aberration is understood, a calculation method used for visual optics is used for calculating and correcting the refraction problem, and the problem which is difficult to understand by eye optics is visualized.

Description

technical field [0001] The technical field of the simulation eye model for teaching of the present invention, in particular relates to a simulation optical eye function model. Background technique [0002] The human eye is often the optical equivalent of a camera. The iris is compared to the shutter, the pupil is compared to the aperture, the crystal is compared to the lens, the retina is compared to the film, and both have lens systems to focus light. Although there are many similarities, the main difference between the two systems is the mechanism by which objects are focused. In a camera, the focal length of each lens is fixed, and changes in focus are caused by movement of the lens. However, in the human eye, it is through changing the curvature of the lens that the optical power of the lens is changed, thereby causing a change in focus. [0003] At present, the physical model of the eyeball is mainly to solve the anatomical structure of the eyeball and a simple model...
