Technical Field

The utility model belongs to the technical field of the medical care technique and specifically relates to an eyesight training device is related to.

Background

With age, the eye accommodation capacity gradually decreases and more people suffer from presbyopia. In order to relieve presbyopia symptoms, vision can be improved by exercising eye muscles, such as exercising eye muscles by exercising the internal and external rotation ability of the eyeball and training three muscles for leading vision by enabling the visual axes of two eyes to constantly move: ciliary muscle, crystalline lens and internal rectus muscle relieve the paralytic stubborn state of the muscles through cooperative exercise, so that the muscles are strong and flexible, the adjusting capacity of eye muscles can be improved, and finally, the purpose of clearly imaging an object on retina and improving eyesight is achieved. Therefore, in order to alleviate the symptoms of presbyopia, a vision training device is needed to improve vision by exercising eye muscles.

Detailed Description

The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention.

The utility model discloses a vision training device, through making the user watch the removal of sighting mark 10, impel the eye to produce by far and near and by near and far linkage regulation to temper eye muscle, reach and keep improving the effect of eye regulating power and set ability even, finally improve eyesight.

Referring to fig. 1 and 2, the vision training device disclosed in the present invention comprises a visual target 10 and a visual target moving mechanism 20, wherein the visual target 10 is used for generating light with a specific wavelength or generating a corresponding image, such as light with a wavelength of 650nm, which may be a light emitting device, such as a light emitting diode, a laser tube, etc., or an image display device, such as a display panel, etc.; the visual target moving mechanism 20 is connected to the visual target 10 and is used for driving the visual target 10 to move towards the eye or move away from the eye.

In practice, the optotype 10 generates light or images with specific wavelengths, a user watches the optotype 10, the optotype moving mechanism 20 further drives the optotype 10 to move back and forth, and the eye is subjected to linkage adjustment from far to near and from near to far, so that eye muscles (ciliary muscles, crystalline lenses and internal straight muscles) are exercised, the eye adjusting capacity and the eye collecting capacity are maintained and even improved, and the vision is improved.

As shown in fig. 2, the sighting mark moving mechanism 20 includes at least one guide rail 21, a base 22 and a shift lever 23, wherein the guide rail 21 extends along the moving direction of the sighting mark 10, the base 22 is slidably disposed on the guide rail 21, the sighting mark 10 is mounted on the base 22, and the shift lever 23 is connected with the base 22. In operation, the base 22 is pushed to move by manually pushing the poking rod 23, and the visual target 10 is driven to move in the moving process of the base 22, so that the distance between the visual target 10 and the eyes of the user is adjusted.

In this embodiment, the sighting mark moving mechanism 20 includes two spaced and parallel guide rails 21, and the base 22 is slidably disposed on the two guide rails 21, but in other embodiments, the number of the guide rails 21 may be set according to actual requirements.

As shown in fig. 2, the optotype moving mechanism 20 further includes rail fixing brackets 24, and the rail fixing brackets 24 are provided at both ends of each of the rails 21 to fix the rails 21.

As shown in fig. 1, the vision training device further includes a housing 30, the housing 30 is used for accommodating the optotype 10 and the optotype moving mechanism 20, and is provided with an observation window 31, and the observation window 31 is used for allowing a user to observe the optotype 10. In this embodiment, the observation window 31 includes two windows 311 disposed at intervals, so that the user can observe the sighting target 10 with both eyes at the same time, of course, in other embodiments, one window 311 may be disposed according to actual requirements.
