Problems solved by technology

However, the method of exercising the external muscles of the eye does not really change the imaging position of the retina (the adjustment of the imaging position of myopia and hyperopia), and it cannot change the shape of the image at all (such as astigmatism)

Embodiment 1

[0018] figure 1 and figure 2 As shown, it is a kind of ciliary muscle training instrument of the present invention, comprising the casing 1 that is provided with window hole, the drive device 8 that is installed in the casing 1 and the visual mark display device 5 that is installed on the drive device 8, the window The hole is equipped with a detachable eyepiece 4, and the driving device 8 includes a guide rail 12, a slide block 13 installed on the guide rail 12 and a stepping motor 6 that provides power to the slide block 13, and the slide block 13 and the stepping motor 6 Be provided with transmission device 7 between, transmission device 7 is a belt, stepper motor 6 is arranged on the casing of one end of slide block 13, is provided with pulley 71 on the rotating shaft of stepper motor 6, on the other end of slide block 13 The casing is provided with a fixed pulley 72, the belt 7 is wound on the pulley 71 and the fixed pulley 72, and the slider 13 is fixed on the belt 7. ...

Embodiment 2

[0028] Such as image 3 As shown, in order to enhance the firmness of the visual mark display device 5 , a support member 51 can also be added between the slider 13 and the visual mark display device 5 . The transmission device 7 between the slide block 13 and the stepper motor 6 can be changed into other transmission modes, the transmission device 7 can be changed into a chain, the stepper motor 6 is arranged on the casing at one end of the slide block 13, and the stepper motor 6 A gear 71 is arranged on the rotating shaft of the slider 13, and a gear 72 is arranged on the casing at the other end of the slider 13. The chain 7 is installed on the gear 71 and the gear 72, and the slider 13 is fixed on the chain 7. When the stepper motor 6 rotates , the chain 7 drives the slider 13 to slide along the length direction of the guide rail 12.

Abstract

The invention discloses a ciliary muscle training device comprising a housing with an observing window, a drive device installed in the housing and a test symbol display device installed on the drive device. The observing window is provided with a detachable eyepiece; the drive device comprises a guide rail, a slider installed on the guide rail and a stepper motor supplying power to the slider; a transmission device is arranged between the slider and the stepper motor, and the test symbol display device is installed on the slider, is connected to a test symbol display control device electrically and is in the same plane with the eyepiece. The device has the advantages that the matching performance of the eye adjusting capability can be improved by training the eye ciliary muscle function, the imaging quality of the fovea can be improved, the visual cell sensitivity is improved, and the prevention and treatment of myopia and amblyopia can be implemented.

Description

technical field [0001] The invention belongs to the technical field of ophthalmology and optics, and more specifically relates to a ciliary muscle training instrument. Background technique [0002] Due to the continuous development of society, the number of people with myopia and amblyopia has become more and more serious in recent years. Because myopia and amblyopia have a huge impact on people's normal life and work, it is urgent to prevent and treat myopia and amblyopia. To solve the problem, people have been using the method of exercising the external muscles of the eyes to prevent and treat myopia and amblyopia. However, the method of exercising the external muscles of the eye does not really change the imaging position of the retina (the adjustment of the imaging position of myopia and hyperopia), and it cannot change the shape of the image (such as astigmatism) at all. Contents of the invention [0003] The purpose of the present invention is to provide a method of...
