Visual training device

Abstract

The invention relates to a visual training device which comprises an upper shell and a lower shell, one end of the lower shell is hinged to the end of the upper shell, an eyepiece is arranged at the end, close to the hinged position, of the lower shell, a display part is arranged at the end, away from the hinged position, of the lower shell, one end of the display part is hinged to the inner side wall of the lower shell, and the display part is used for displaying images for visual training; when the upper shell and the lower shell are closed, a relatively closed cavity is formed, and the display part is accommodated in the cavity; when the display part is opened, the display part is overturned and erected, and visual training is performed by observing training images of the display part through the eyepiece; and by means of the structural arrangement, the structure is small, exquisite and attractive, carrying and using are convenient, using is very convenient, using or storage can be easily achieved through opening and closing, and troublesome adjusting procedures are not needed.

Description

technical field [0001] The invention belongs to the field of vision devices, in particular to the field of vision training devices. Background technique [0002] With the popularization of electronic equipment and products, people are spending more and more time actively or passively on electronic products. Often, the eyes are concentrated on books, computers, and other close-up objects for a long time, causing pressure on the eyes. , make the ciliary muscle fatigue or even spasm, slowly the glasses look more and more blurred, the distance to see the object is getting shorter and shorter, and gradually develop into myopia; in order to relieve the visual fatigue caused by long-term use, there are A lot of equipment for vision relief or training, such as vision training equipment, which trains the eye muscles by training the ability of eyeballs to rotate in and out, and makes the visual axes of the two eyes move continuously to train the three muscles that dominate vision --- ...

[0002] With the popularization of electronic equipment and products, people are spending more and more time actively or passively on electronic products. Often, the eyes are concentrated on books, computers, and other close-up objects for a long time, causing pressure on the eyes. , make the ciliary muscle fatigue or even spasm, slowly the glasses look more and more blurred, the distance to see the object is getting shorter and shorter, and gradually develop into myopia; in order to relieve the visual fatigue caused by long-term use, there are A lot of equipment for vision relief or training, such as vision training equipment, which trains the eye muscles by training the ability of eyeballs to rotate in and out, and makes the visual axes of the two eyes move continuously to train the three muscles that dominate vision --- ciliary Muscles, extraocular muscles, and iris muscles, through coordinated exercise to relieve the paralysis and stiffness of the above muscles, make them strong and flexible, thereby improving the adjustment ability of the eye muscles, and finally achieve the clear imaging of objects on the retina and restore vision. However, most of the vision training devices on the market are mechanically movable structures. Taking CN200610146531.7 as an example of a vision training device, the device realizes the mechanical movement of the vision target on the bracket through a reciprocating telescopic mechanism. , and then play the role of adjusting the distance between the vision target and the observer; although it can play a certain training effect, the device is too large and very cumbersome, and it is inconvenient to use. location using
