The technical solutions in the examples of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the examples clearly described are examples of a part of the present invention. Not all examples. Based on the examples in the present invention, all other examples obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

In order to make the above object, feature and advantage of the present invention more remarkable and easy to understand, the present invention will be described in more detail below with reference to the drawings and embodiments for carrying out the invention.
First, the nature of eye fatigue will be explained. According to the principle of vision, photoreceptor cells on the retina include rod cells and pyramidal cells, and pyramidal cells are classified into three types: red-sensing cells, green-sensing cells and blue-sensing cells. The photosensitive substance in the photoreceptor cells is a photosensitive dye. The photosensitive dye in the rod cells is rhodopsin, and the photosensitive dye in the pyramidal cells is iodopsin. The photosensitive dye in a dark place is purple-red, and when it encounters light, a photochemical reaction occurs, the photosensitive dye immediately decomposes into opsin and retinaldehyde, the color becomes white, an electric pulse is emitted, and the brain emits an electric pulse. When you receive, your eyes can see. Since the decomposed photosensitive dye is resynthesized in a dark place, the photodecomposition and resynthesis of the photosensitive dye form a dynamic balance. Because this is a physiological process of metabolism, photochemical reactions are fast and resynthesis is much slower. Therefore, if the fixed target is stared at for a long time, the balance between photodecomposition and resynthesis of the photosensitive dye will be lost. If you don't want to tire your eyes, you need to find a way to keep the balance between photolysis and resynthesis of the photosensitive dye low. Rod cells are sensitive but prone to saturation, and during the day when there is ample sunlight, rod cells are in a saturated state and do not function. If you suddenly enter a dark place from a bright place, it will take time for the rod cells to return to their original state, and you will not be able to see. Although the sensitivity of the pyramidal cells is low, the working time is long, and only the fatigue of the pyramidal cells will be described here. If you look around in your daily life, your eyes will not get tired. This is because the three pyramidal cells have a single function. Red-sensing cells are sensitive only to red light, but do not appear green and blue, which means that red-sensing cells are resting when only green and blue light are applied. Similarly, when only red light and blue light are irradiated, the green sensing cells are also resting, and when only red light and blue light are irradiated, the blue sensing cells are also resting. Therefore, if the eye scene changes frequently, each pyramidal cell can get many resting moments and the eye does not get tired.
Next, the cause of deep eye fatigue will be explained. Many pyramidal cells are concentrated in the macula in the center of the fundus, and when an image of an object is projected onto the macula, the details of the object can be clearly seen, so that a person tends to stare at the object. When a stationary object is viewed for a long time, the photoreceptor cells accumulate a large amount of photosensitive pigment that is discolored but too late to be resynthesized, which is the essence of eye strain. No one can see a completely fixed scene for a long time, and severe fatigue causes the eyes to shift unconsciously. However, in practice, people often force them to see "roughly" still images for extended periods of time. For example, when looking at a mobile phone, the screen of the mobile phone is dynamic, but because the mobile phone is small and the field of view of the eye is wide, what is visible is an image that is almost stationary, and at this time, inside the photoreceptor cells. Accumulates a large amount of photosensitive dye that is too slow to be resynthesized. Therefore, the brain commands the dilation of the capillaries, the increased blood supply to the eye, and the rate of resynthesis of the photosensitive dye, at which time the eye is in a state of severe fatigue. There are many similar situations: watching a computer for a long time, reading a book, watching TV, writing homework, etc. All these situations cause eye fatigue, which is a major cause of myopia in adolescents.
Ophthalmologists have discovered the cause of myopia after decades of research. Adolescents are in a period of growth, the body has many growth factors, and when the eyes are tired, it activates the growth factors of the liver, promotes eye growth again, lengthens the eye wheelbase, and myopia. become. Therefore, watching an almost stationary scene for a long time is a bad habit that tires the eyes and is a major cause of personal computer disease and myopia.
How long is "long time"? How can I quantitatively explain the degree of eye fatigue? The following is determined by a negative image experiment. Under certain conditions, the eye can sense the presence of discolored photosensitive dye. For example, if you look at a mobile phone in a dark room and turn it off, a white shadow on the screen of the mobile phone is immediately visible, and this shadow is formed by the discolored photosensitive dye. This shadow gradually disappears due to the resynthesis of the photosensitive dye. The principle of eye imaging is similar to that of cameras, and in the past, the films used in old-fashioned cameras were also called "negative films", so the shadows that appear in the eyes are called "negative images". There is. The shadow formed by the decomposition of the photosensitive pigment of rod cells is white. The shadows formed by the decomposition of the photosensitive pigments of the pyramidal cells exhibit complementary colors. The experimental process is as follows. After looking at the computer for a while in a dark room, turn off the computer and record the time until the negative image disappears. Next, the different times of staring at the personal computer and the existence times of the corresponding negative images are recorded, a coordinate graph is drawn, and FIG. 1 is shown. In FIG. 1, the X coordinate is the time for viewing a personal computer, the Y coordinate is the time for a negative image to exist, and each point is connected to draw a curve, and as shown in curve 1, that is, a visual cell fatigue curve. Since the time when the negative image disappears indicates the degree of eye fatigue, the Y coordinate is also called the fatigue index. According to FIG. 1, time can be divided into three stages. In the first stage, watching a personal computer for 10 minutes is defined as a critical point. If it is shorter than 10 minutes, the photosensitive dye of the eye is in a balanced stage of photodegradation and resynthesis, and the eye does not get tired. The second stage, from 10 minutes to 30 minutes, due to the slow resynthesis rate of the photosensitive dye, the decomposed photosensitive dye increases rapidly, which belongs to the mild fatigue stage of the eye. In the third stage, when the personal computer is viewed for longer than 30 minutes, the slope of the ascending curve gradually becomes flat. This is due to dilation of capillaries, increased blood supply, and increased rate of resynthesis. This is a stage of deep eye fatigue.
The above experiments demonstrate that even one hour of use of the eyes can cause that deep fatigue. However, 10 minutes is too short, so long-term eye use can be transformed into multiple short-term eye use clusters, or a nearly fixed image can be transformed into a frequently changing image. However, changing the local part does not have a good effect, so it is necessary to change the entire field of view. Everyone should have two eyes and alternately look at one eye. If you design some kind of eyeglasses, your eyes will not get tired if they work in turn every scheduled time (eg 2 minutes) and change their field of vision frequently. Based on the above principle, some experimental eyeglasses are designed below, which are composed of a timing controller, a plastic sheet, eyeglasses, an electromagnet and a small magnet sheet. The timing controller can change the direction of the electromagnet's current every two minutes, so the electromagnet can attract or reject a small magnet sheet, and the plastic sheet can rotate at an angle to cover the other eye. can. By repeating many experiments using experimental glasses, a very excellent anti-fatigue effect can be obtained. For example, personal computer illness is caused by looking at the screen of a personal computer every day. After wearing the experimental glasses, the symptoms of computer disease disappeared within 2 days. And in the negative image experiment after wearing the experimental glasses, the eye fatigue index is less than 3 no matter how long the total time of eye use is, see curve 2 in FIG.
Therefore, based on the above principle, spectacle control circuits, anti-fatigue spectacles and anti-fatigue spectacle control methods can be designed to more comprehensively solve the problem of eye fatigue and then solve the problem of youth myopia. ..

The principle for realizing the spectacle control circuit of this embodiment was as follows.
Inside the first chip CD4060 in the spectacle control circuit of this embodiment, there is an oscillator and a 14th stage divider, and the fourth resistance R4, the fifth resistance R5, and the capacitor C2 constitute an oscillator assembly. Since the frequency of the oscillator was too high, after the 14th stage division, a square wave with a period T was output from the output end Q12 of the 12th stage, and a square wave with a period 2T was output from the output end Q13 of the 13th stage.

The anti-fatigue glasses of this example had the following advantages.
1) According to the principle of vision, staring at a still image for a long time is a major cause of fatigue of the pyramidal cells of the eye. In this embodiment, two states of the liquid crystal spectacles, that is, a transparent state and a dense fog state, are used to change the long-time eye use into a plurality of short-time eye use gatherings. The eye fatigue index was kept low (fatigue index 3 or less) to prevent pyramidal cell fatigue.
2) Conventional liquid crystal glasses mainly use black liquid crystal, and the anti-fatigue glasses of this embodiment use light color liquid crystal (for example, white liquid crystal), so that the brightness of the lens changes significantly at the time of state transition. By not doing so, it was possible to prevent pupil fatigue.
3) Conventional liquid crystal glasses are controlled by alternating current, and the flicker effect caused by alternating current certainly causes eye fatigue. The control circuit chip of this embodiment adopts long-period AC / DC control technology to periodically change the output state during operation, thereby realizing the change between the transparent state and the non-transparent state of the liquid crystal lens. It prevented fatigue, had no flicker, and the lens was clear and stable.
4) People are accustomed to seeing nearby objects with binoculars, and the binocular line of sight is slanted and angled, and long-term attention makes the extraocular muscles tired. The anti-fatigue glasses of this embodiment can see things in order with one eye and relieve the fatigue of the extraocular muscles, and in cooperation with the combination lens consisting of a plane mirror and a convex lens, the problem of eye fatigue is completely solved. I was able to solve the problem of myopia in adolescents.

This example provided an anti-fatigue eyeglass control method, which was used for the anti-fatigue eyeglasses provided in Example 2. The anti-fatigue eyeglass control method includes the following.
When the voltage applied to the lens is positive or negative, the lens is in a transparent state, and when the withstand voltage is 0, the lens is in a dense fog state.

Specific examples are provided below.
In this specific embodiment, the output end Q12 of the 12th stage of the first chip is controlled to output a square wave having a period of 2 minutes, and the output end Q13 of the 13th stage of the first chip is controlled. A square wave with a period of 4 minutes was output. In the anti-fatigue spectacle control method, the timing diagram of each point of the spectacle control circuit is shown in FIG. 4, in FIG. 4, the unit of time is minutes, and the cutting lines of U1 and U2 are the actual cutting lines to the lens. It was an applied voltage. With reference to FIG. 4, the motion sequence of the anti-fatigue glasses is as follows.
1) During the period from 0 to 1 minute, both the output end Q12 of the 12th stage and the output end Q13 of the 13th stage had low potentials, so that the second electronic switch K2 and the third electronic switch K3 were turned off. The output end Q13 of the 13th stage was connected to the inverter F, the inverter F output a high potential, and the first electronic switch K1 and the fourth electronic switch K4 were turned on. Therefore, the connection end JP1 of the left lens was connected to the power supply V and became high potential, and the connection end JP2 of the right lens was connected to the ground and became low potential. Since the reference end M had a low potential, the voltage U2 applied to the right lens was 0, and the voltage U1 applied to the left lens was a positive voltage, that is, the cutting line of U1 in FIG.
2) During the period from 1 to 2 minutes, the output end Q13 of the 13th stage is still at a low potential, the second electronic switch K2 and the third electronic switch K3 are still turned off, and the first electronic switch K1 and the fourth are. The electronic switch K4 was turned on, the connection end JP1 of the left lens had a high potential, and the connection end JP2 of the right lens had a low potential. However, since both the output end Q12 and the reference end M in the twelfth stage had high potentials, the voltage U1 applied to the left lens was 0 and the voltage U2 applied to the right lens was a negative voltage.
3) During the period of 2 to 3 minutes, the output end Q13 of the 13th stage had a high potential, so that the second electron switch K2 and the third electron switch K3 were turned on, and the first electron switch K1 and the fourth electron were turned on. The switch K4 was turned off, and at this time, the connection end JP1 of the left lens was connected to the ground and became low potential, and the connection end JP2 of the right lens was connected to the power supply V and became high potential. At this time, since the reference point M had a low potential, the voltage U1 applied to the left lens was 0, and the voltage U2 applied to the right lens was a positive voltage.
4) During the period of 3 to 4 minutes, the output end Q13 of the 13th stage is still at high potential, the second electronic switch K2 and the third electronic switch K3 are still on, and the first electronic switch K1 and the fourth are. The electronic switch K4 is turned off. At this time, since the reference point M had a high potential and the connection end JP1 of the left lens had a low potential, the voltage U1 applied to the left lens was a negative voltage. Since the connection end JP2 of the right lens had a high potential, the voltage U2 applied to the right lens was 0. It circulated in this way, and one cycle took 4 minutes.

It is an anti-fatigue eyeglass control method of this embodiment, and a long-period AC / DC technique is adopted as the control method, and when energized, the two lenses exhibit a transparent state and a non-transparent state such as thick fog, respectively. Every few minutes, the two lenses change state at the same time, that is, from transparent to non-transparent like thick fog, and from non-transparent to transparent.
