Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, most of the explanations are explained through video in the case of simulating the myopia with elongated eye axis, but the video explanation of axial myopia is not only not intuitive, but also cannot clearly express the change of eye axis, which is inconvenient To understand the causes of axial myopia, the present invention proposes a bionic eyeball teaching aid for simulating eye axis changes in myopia

Embodiment 1

[0034] see Figure 1-11As shown, a bionic eyeball teaching aid for simulating eye axis change myopia includes a camera bottom case 1, a camera top case 2, a light source and a bionic eyeball assembly; the camera top case 2 is covered on the camera bottom case 1; The eyeball assembly is arranged inside the camera bottom case 1; the light source is arranged outside the camera bottom case 1; the bionic eyeball assembly includes the outer bottom casing 4 of the eyeball, the top outer casing 5 of the eyeball, the light screen 6 and the first eyeball mechanism; The eyeball outer bottom shell 4 is arranged inside the camera bottom shell 1, and the eyeball outer bottom shell 4 is provided with a first groove 41; the first groove 41 is provided with a plane mirror 42; the eyeball outer top shell 5 is covered on the The top of the outer bottom shell 4 of the eyeball, the outer top shell 5 of the eyeball is provided with a second groove 51; the second groove 51 is compatible with the pla...

Embodiment 2

[0045] see Figure 12 As shown in Comparative Example 1, as another embodiment of the present invention, a rubber pad 84 is provided on the inner wall of the first positioning hole 83; during operation, by setting the rubber pad 84 in the first positioning hole 83, This makes the connection between the first eyeball inner bottom shell 7 and the first eyeball inner top shell 8 more stable.

[0046] Steps:

[0047] The average axial length of human normal eyeballs is 24mm, and the axial length of axial myopia is greater than 24mm. In order to facilitate experimental observation, this teaching aid model is made by magnifying the normal human eyeball and human axial myopic eyeball 10 times. teaching aids, so that it is convenient for the staff to carry out simulation experiments.

[0048] 1. Axial myopia eyeball simulation experiment: The first eyeball mechanism simulates the human axial myopia eyeball structure. In order to facilitate the staff to observe the experimental pheno...

Abstract

The invention belongs to the technical field of bionic teaching aids, and particularly relates to a myopia bionic eyeball teaching aid for simulating eye axis change, which comprises a camera bottom shell, a camera top shell, a light source and a bionic eyeball assembly, the camera top shell covers the camera bottom shell; the bionic eyeball assembly is arranged in the camera bottom shell; the light source is arranged outside the camera bottom shell; the bionic eyeball assembly comprises an eyeball external bottom shell, an eyeball external top shell, an optical screen and a first eyeball mechanism; the eyeball external bottom shell is arranged in the camera bottom shell; the eyeball external top shell covers the top of the eyeball external bottom shell, and a second groove is formed in the eyeball external top shell; the first eyeball mechanism is arranged in the eyeball external bottom shell; the optical screen is arranged in the first eyeball mechanism; through the light source irradiation device, images on the light screen are compared and observed, a myopia simulation experiment is completed, and the cause of axial myopia can be understood conveniently.

Description

technical field [0001] The invention relates to the technical field of bionic teaching aids, in particular to a bionic eyeball teaching aid for simulating eye axis changes and myopia. Background technique [0002] Axial myopia is a kind of myopia caused by congenital or acquired factors that elongate the front and rear diameter of the eyeball (that is, the axial length of the eyeball). The average axial length of the normal eyeball is 24mm, while the axial length of the axial myopia is greater than 24mm. , when the parallel light rays enter the eyeball, the focal point falls in front of the retina and cannot be clearly imaged. [0003] At present, in the existing technology, when simulating the myopia with elongated eye axis, most of the explanations are explained through video, but the video explanation of axial myopia is not only unintuitive, but also cannot clearly express the change of eye axis, which is not easy to understand axial myopia. The cause of formation of myo...
