Description
Technical Field
the invention belongs to the technical field of glasses, and relates to a system and equipment for preventing amblyopia of teenagers by using optical frequency.
Background
According to statistics of education department, 1.752 million people exist in primary and secondary school students in China, wherein half of the students have amblyopia; the cause of improper use is the main reason. Eye health care of teenagers becomes a very important thing for the nation.
How to effectively protect the eyes of teenagers and reduce amblyopia groups is a problem that researchers must go straight.
The eye problem needs to be solved by eyes, and the problem is solved from the root. The eye has a strong self-repairing function, enhances the movement of the eyes and can help amblyopia well. How to effectively move eyes, the country puts forward eye exercises.
Eye exercises, while helpful in eye care, do not address the underlying problem. The physical massage therapy does not play a great role in recovering asthenopia.
To move the eyeballs and obtain sufficient movement without dead angles is a very important thing for treating amblyopia and correcting eyesight.
Through research, when the pupil encounters strong light, the contraction of the sphincter pupillae drives the natural contraction of the pupil. Under the dark environment, the opening muscle of the pupil relaxes, and then drives the pupil to expand, adopts this principle, and the illumination that replaces through certain frequency dark and bright light just can let the pupil regularly contract and enlarge, and then reaches the effect of motion eyeball, and the purpose of supplementary crystalline lens correction focus of recovering.
we further design the glasses according to the above, and stimulate the eyeballs to perform spontaneous contraction movement by switching the light with a certain frequency between dark and bright, so as to strengthen the eye muscles, promote the blood circulation of the eyes and reduce the eye diseases.
the glasses can not only strengthen eye muscles and strengthen eyesight by stimulating pupil contraction, but also enable the attention of a user to be highly concentrated, relax the brain, accelerate learning speed and obtain long-time brain awakening.

The function and technical basic description of the application:
1. description of the function
improving eyesight, preventing amblyopia, improving attention, relieving brain fatigue, and improving brain reaction ability.
2. Basic theory of technology
Through an optical frequency technology, LED light switching is realized for 1-30 times within 1 second, and when the LED light is switched on each time, the eye pupil penetrates through eyelid to feel strong light, the pupil contracts and the sphincter contracts; when the LED lamp is turned off every time, the eye pupils penetrate through the eyelid to feel darkness, the pupil is enlarged, and the opening major muscles are relaxed; through LED light switch 1 ~ 30 times per second, every pupil enlargies at the speed of 1 ~ 30 times per second, contracts, drives the contraction of eye sphincter and division major muscle, and then drives whole eyeball neuromuscular contraction motion, strengthens eyeball neuromuscular, prevents that eye neuromuscular from pressing the deformation and forming amblyopia because of the spasm that long-time sight arouses.
through the optical frequency technology, the strong light flickers in the eye closing state of a user, the strong light flickers through eyelids and is projected to optic net nerves through eye pupils, the strong light flickers are carried out by the frequency of brain waves, the brain waves are relaxed at the same frequency according to a certain rhythm, the sleepiness and the confused state of thinking are relieved, and finally the brain waves are in the state of peaceful and peaceful brain waves, so that the brain waves are more beneficial to clear judgment, study, reading and work in the state of brain relaxation.
The using method comprises the following steps:
1. the user can sit comfortably, the eye cover is worn on the glasses, and the LED lamp beads are opposite to the eye pupils;
2. inserting the earplug into the ear hole;
3. And starting a controller switch until the spectrum program is finished and is extinguished.
Example of optical frequency program of the present application:
we selected 40 primary and secondary school students in the guangzhou river, 20 of which were male and 20 of which were female, and made the corresponding tests, and the results were as follows:
Example first and second program effect comparison table
by contrast, the sequential frequency-increasing and speed-decreasing method can relieve the tiredness of primary and secondary school students in class at a higher proportion, and the effect of improving the vision is relatively close.
Through research, the sequential frequency-increasing and speed-decreasing method is determined to be more suitable for being popularized to primary and secondary school students for eye and brain health care. Through the rapid reduction of the frequency, the brain frequency of the student cannot easily enter a sleep band. Although the gentle frequency raising and lowering method stops at the frequency of 5HZ, the brain frequency fluctuation still falls down through inertia, and the students are sleepy.
the invention has the beneficial effects that:
The pupil can be regularly contracted and enlarged by switching the illumination with dark and bright light at a certain frequency, so that the effect of moving the eyeball is achieved, and the purpose of restoring and correcting the focal length by the crystalline lens is assisted.
stimulating the sphincter and the sphincter of motor and the sphincter of digitorum by illuminating and contracting pupil, and stimulating the movement with light frequency for more than 3900 times every 4 minutes; the movements were stimulated optically every 9 minutes for about 9000 times.
the light with a certain frequency is switched between dark and bright to stimulate the eyeballs to do spontaneous contraction movement, so as to strengthen the eye muscles, promote the blood circulation of the eyes and reduce eye diseases.
The glasses can not only strengthen eye muscles and strengthen eyesight by stimulating pupil contraction, but also enable the attention of a user to be highly concentrated, relax the brain, accelerate learning speed and obtain long-time brain awakening.
