Abstract

The present invention provides an eyeball teaching model with eyelids. A sclera, a cornea, an iris, a pupil, a crystalline lens, ciliaris, a vitreous body, a retina, optic nerves, the eyelids and eyelashes are combined together according to an actual structure so as to form the eyeball teaching model. Compared with an eyeball teaching model which is used widely at present, the eyeball teaching model of the invention is further provided with the eyelids and the eyelashes. The eyelids can be arranged on an eyeball or can be removed from the eyeball. When a student learns the eyeball with the eyeball teaching model adopted, he or she can easily understand that the white part of the eyeball is the sclera, and the black part of the eyeball is the iris, and will not confuse the eyelids, the sclera, the cornea, the iris and the pupil, and therefore, the student can learn the structure of the eyeball quickly, and memorize the structure of the eyeball deeply.
