Description

Eye protection instrument

Technical Field

The invention relates to an eye protection article, in particular to an eye protection instrument without adjusting the visual distance.

Background

The modern people use far more eyes at a short distance than at a long distance, because the eye muscles are in a tense state when the modern people use the eyes at the short distance, when the modern people see near for a long time, ciliary muscles are easy to continuously contract and spasm, the diopter of crystalline lens is increased, so that blurred vision is generated, eyeballs are in a near-sighted state (pseudomyopia with obviously reduced far vision), and the clinical manifestations of blurred vision, low far vision, asthenopia and eyeball change are mainly presented, the symptoms are light and heavy, the attack rule is unstable, and some patients also have the clinical manifestations of ghost images, photophobia, foreign body sensation in eyes and headache with different degrees. If the pseudomyopia cannot be relieved in time, the pseudomyopia can become true myopia, and usually, the patient can recover the pseudomyopia by exercising eye muscles.

Once true myopia is formed, the existing medicine still has no good method for treating true myopia, methods such as glasses wearing or laser surgery are mostly adopted, the method cannot radically recover the vision of a patient, only corrects the vision, and the vision correction aggravates the fatigue degree of near-distance eyes (when people with myopia glasses see the near, namely, when people with higher degrees see the near, the eyes are tired when people see the near, and the vicious circle is caused).

The most effective method is to make eyes relax in time and to make people look far away frequently, and people are difficult to draw time to train eyes to look far away in busy work or study process. Even if the user needs to take time to look far, the user only needs to look far outdoors, and for a pseudomyopia person, the user can clearly see a certain object to look far gradually to train the vision of the eyes, and the traditional looking far training is difficult to accurately grasp.

For example: the logo 4 adopts english letters A, B, C, D, E, F, G, H, I as a first logo 4, a second logo 4, a third logo 4 … and a seventh logo 4, respectively.

2) Training in a mode of switching between the identifiers 4 is as follows:

a. rapidly relaxing the eyes: the lights are switched from a to B, C, D, E, F, G, H, I in turn by the master control circuit directing the lights.

The eye can be relaxed rapidly (obvious moist feeling when the eye is worn) by repeating B, C, D, E, F for the letter A and the letter A in sequence to the last letter which can be seen clearly by the eye.

b. Alternate training between far and near: the guide light jumps directly from a to the most distant clearly visible font, e.g., F, after which it is switched repeatedly between a and F.

Starting with the letter a, looking again B, C, D, E, F, I in order until the last letter is visible to the eye, then looking at a, and jumping directly to the last letter that is visible, the eye exercises the eye by repeatedly switching between the two letters.

The farthest clearly visible letters are watched by the two eyes, the head is moved up and down to the largest range where the eyes can clearly see, and the far-point sight distance range of the eyes is trained.

The head of the instrument is fixed, the eyes move to the maximum range leftwards, then the farthest clearly visible letters are watched again, the eyes move to the maximum range rightwards, and then the farthest clearly visible letters are watched again.
