[0025] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application.

[0027] Spherical main body 1 for simulating life eye, the spherical main body 1 is at least provided with pupil simulation part 2, lens simulation part 3 and vitreous simulation part 4;
[0028] The pupil simulation part 2 includes adjustable diaphragm, for realizing the size adjustment of simulating life pupil;Diaphragm is an optical element, mainly used for controlling the propagation of light beam.In optical system, the role of diaphragm is to limit the cross section of light beam, thereby affecting the performance of imaging system, such as can control the amount of light entering the optical system, determine the definition and resolution of imaging.The working principle of continuous variable diaphragm is mainly through changing the size of diaphragm opening to adjust the amount of light passing through optical system.Continuous adjustable diaphragm is usually composed of multiple blades, which are arranged around a center point and can overlap each other.Adjustable diaphragm mainly includes two types of adjustable manual diaphragm and adjustable electric diaphragm, namely electronic control and mechanical control.For example, the size of aperture can be adjusted by rotating the aperture ring on the lens.
[0029] The lens simulation part 3 includes water lens, for realizing the concave-convex degree adjustment of simulating life lens;The concave-convex degree of water lens can be adjusted by the refractive index of water, and the concave-convex degree refers to the change of surface curvature, and the water lens utilizes the characteristics that the refractive index of water changes with temperature, adjusts the focal length and curvature of the lens by changing the water temperature, so as to realize different optical effects.
[0030] The vitreous simulation part 4 includes light source imageable area for simulating retina.
[0031] The existing human eyeball model only shows the components of the structure, assembles a complete eyeball structure, and cannot adjust the lens and pupil. Therefore, the internal structure is adjusted on the basis of the existing eyeball, a water lens is used to simulate the adjustable lens, and an aperture model is used to adjust the pupil. Thus, the life eyeball structure simulation device provided in the embodiments of the present application can not only realize the simulation and display of the structure of the life eyeball, but also realize the simulation of the adjustment of the size of the pupil of the life body through the provided adjustable aperture, the simulation of the adjustment of the concave-convex degree of the lens through the water lens, and the simulation of the retina through the light source imageable area.
[0032] It can be seen that the device provided in the present application realizes the simulation of the change of the lens of the real eyeball model. The lens in the structure of the real human eyeball model can self-adjust the concave-convex degree of the lens within a certain range due to the tension and relaxation of the ciliary muscle under normal circumstances, so that the picture seen by the human eye can be clearly imaged in the retina and transmitted to the cerebral cortex.
[0033] In actual application, the water lens can be made of various materials, for example, in one implementation, the water lens can be made of an elastic film. The water lens can be made of a high-elasticity film to simulate the adjustable lens.
[0034] Further, the light source imageable area is formed on the vitreous body by using an opaque white material.
[0035] In order to enable the device to simulate the complete structure of the life eyeball, the embodiments of the present application can also provide that the spherical main body 1 is further provided with a cornea simulation part 5 and an iris simulation part 6.
[0036] In order to facilitate the assembly and manufacturing, the embodiments of the present application can also provide that the spherical main body 1 comprises a left half eyeball 11 and a right half eyeball 12 which are connected to each other.

In actual teaching use, the spherical main body 1 can be installed at a suitable position through the fixed support rod 7 for the use of teachers in teaching and students in observation.
[0038] In summary, the eyeball structure simulation device provided by the application can not only simulate the self-adjusting change of the real lens of the eyeball model, but also increase the component for simulating the pupil expansion and contraction adjustment, so that the self-adjusting function of the real pupil in the human eyeball when encountering light intensity can be simulated.
