Description
Technical Field
The present invention relates to: a bionic visual training instrument capable of supplementing light for the posterior pole of the eye ground and the peripheral visual field of the eye ground. Background
The incidence of myopia in recent years is high, and the fourth national student physique survey in 2000 shows that the myopia rate of students in China is as follows: 20.23% of pupils, 48.18% of junior middle school students, 71.29% of senior high school students and 73.01% of college students. One survey in hong Kong shows that the myopia rate of primary school students is very common, and the myopia rate of six-grade primary school students is as high as 60%, which is twice as high as that of New York; the myopia rate of middle school students is estimated to be more than 75%. The myopia rate of taiwan students is also high, with primary school students 12% grade one, 55% grade six, middle school students 76% grade three, and high school grade three 85%. Foreign situations are also not optimistic, for example, the vision defect rate of the students in the third grade of high school in Japan is 57%, the myopia rate of the graduates in high school in Singapore China is 78%, the myopia rate of the general population in the United states is one third, and the myopia rate in European areas is less but a large number of myopia groups still exist. The investigation shows three worried points, namely more and more myopia people, deeper and deeper myopia degrees and younger myopia people, which bring great inconvenience to the study and life of students.
Study progress of histological change of high myopia [ J ] Tianjin medicine, 2017,45(06): 657-: "the thickness of the sclera at the limbus of the eye with the axis below 26mm is about (0.50. + -. 0.11) mm, the thickness decreases to (0.43. + -. 0.14) mm from the serration, the equatorial region is (0.42. + -. 0.15) mm, the mid-portion between the equatorial region and the posterior pole is (0.65. + -. 0.15) mm, the peri-optic nerve is (0.86. + -. 0.21) mm, the posterior pole is (0.94. + -. 0.18) mm, and the thinnest is (0.39. + -. 0.09) mm at the optic disc lamina cribrosa. The highly myopic posterior sclera stretches unevenly and the average thickness of the sclera decreases from the equatorial to the posterior polar. "
Optic disc (optical disc): the retina has a pale red disc-shaped structure with a diameter of about 1.5mm from the macula lutea to the nasal side of about 3mm, and is called optic disc, which is called optic disc for short. This is the site on the retina where the optic fibers converge out of the eye where the thinnest thickness of the sclera is physiologic and is the beginning of the optic nerve.
It can be seen that myopia, especially high myopia, has the weakest elongated sclera at the equator of the eyeball
The second elongated weak portion is the posterior pole of the eyeball.
Myopia and amblyopia of teenagers become social problems worldwide. According to the latest statistics, 3.5 hundred million myopia patients in China exist; the myopia rate in the united states is about one third of the average population. In other words, nearly 20 billion myopes are around the world and are still rolling and growing in number. The current incidence rate of amblyopia of children in China is nearly five percent, and the number of amblyopia patients in children is over 2000 ten thousand. The causes of amblyopia mainly include three kinds of ametropia, such as high myopia, high hyperopia and high astigmatism, high ametropia formed by the three kinds of ametropia and monocular disuse strabismus caused by the high ametropia.
Xuguang is known as Xuguang in ophthalmology Qu Zhi, page 57: nearly all wild birds and beasts on land are slightly hyperopic or emmetropic (i.e., nearly all birds and beasts on land are not near sighted, highly hyperopic, astigmatic, and amblyopic).
The theme of the national love day of 6 months and 6 days in 2017 is: the eyes can be used for bathing in sunlight to prevent myopia.
Therefore, the mainstream ophthalmology in China also pays attention to the bionics, and animals with good eyes in nature and people with poor vision are compared. This is a big good thing, and will help to improve vision or maintain good visual function. However, indoor and outdoor are not all good and bad eyesight. The fundamental difference between good-eyed animals and people with poor vision lies in the habit of using the eyes-a position in the food chain-which is the forming motive of good vision. For example:
outdoor animals with poor vision: brown bear, elephant, rhinoceros, etc. are relatively powerful and grazing animals in their own territories, also outdoors, but their vision is not good. The reason for this is that they do not have the motivation to require good vision, and these animals don't dare to come out to eat them in their own territories without preventing natural enemies. At the same time, because these animals eat the meal, they also have no desire to eat other animals, without discovering and chasing other animals. So that the vision of such animals is mostly poor.
Animals with good outdoor vision: the vast majority of animals at the lower end of the food chain or carnivorous animals at the upper end of the food chain are afraid of being eaten by other animals or needing to search other animals as food, and seven unique eye habits (see the bottom of the specification and comments on seven bionic visual training) which are not possessed by human beings are developed, so that the eyesight of the animals is very good. It is said that: the animal can not be shortsighted because the animal does not need to read a book and uses eyes for a long distance. In fact, the animals can pass through the grass, and the distance between the plants and the eyes is not longer than the distance for reading books. In addition, the eyes of the birds always look at the millet in the millet pecking process, the eye using distance of the birds is very short, is usually less than 2-3 cm, and is much shorter than the distance of the people for reading books. However, there are data: the vision of birds is the best of all animals.
Indoor good-eye person: people are good at all around, and people cannot see myopia, hypermetropia, astigmatism or amblyopia when lying down to read books.
Therefore, the indoor and outdoor vision is not the determining factor of the good or bad vision, and the vision desire and the habit of using eyes are the forming motive force of the good or bad vision.
The researchers of the invention use the time of several years, and find seven reasons that the good eyes of the human or the animals in the nature can not be shortsighted through the quiet heart → the close nature → the feeling nature → the natural law nature. Here, only one of the most important reasons (see the annotation contents of seven kinds of bionic visual training at the end of the specification for other reasons) is listed: all animals are afraid of being eaten by other things, the peripheral vision field of the animals is very good, and the peripheral vision field is concerned about, pays attention to and sees by any wind blowing to weed the animals, and is afraid of the appearance of natural enemies. The peripheral visual field is well used, and the blood circulation of the sclera at the corresponding part is good, so that the development activity of the sclera is strong, or the tensile tension of the sclera is strong. High hyperopia, which is not associated with a strong scleral development activity, and high scleral tensile tension, which is not associated with myopia, astigmatism or decentral-fixation strabismus (the first focus of astigmatism or decentral-fixation and corresponding strabismus of the abnormal retina, consisting in a local elongation beside the fovea of the fundus retina).
Different from wild animals, people are not afraid of jumping out of the field to eat the wild animals, only pay attention to the object to be seen in front, the peripheral visual field can be completely ignored, and the peripheral visual field of the eyeground cannot be stimulated. So there is an article written by ophthalmologists: the peripheral visual field of the eyeground has serious ischemia at the initial stage of myopia (foreign video data indicates that visual cells and the sclera at the corresponding part are a blood vessel for supplying blood). Just because the blood circulation in the peripheral visual field of the ocular fundus is poor, the sclera of the corresponding portion is in a sub-healthy and weak state with insufficient nutrition supply. This may result in insufficient scleral developmental activity, or insufficient scleral tensile tension. If the development vigor of the sclera is insufficient, hypermetropia can be obtained, and if the tensile tension of the sclera is insufficient, myopia, astigmatism or other side-center staring strabismus and amblyopia caused by the strabismus can be obtained.
Components of outdoor sunlight include infrared, visible, and ultraviolet rays. The prior art considers that ultraviolet light with short wavelength and blue light close to the ultraviolet light are harmful to a visual system, so the concept of anti-ultraviolet and anti-blue light glasses is provided. And the longer wavelength light of the visible light, yellow light, red light and infrared light, is considered to be safer, and the longer wavelength light is safer for the same dosage.

Advantageous effects
The invention has the beneficial effects that: the invention finds the following in a new way through bionics: hypermetropia caused by insufficient development activity of sclera, myopia, astigmatism or lateral central fixation strabismus caused by insufficient tensile tension of sclera and amblyopia caused by the same are both derived from the neglect of peripheral vision of human beings and from the deficiency of blood circulation of the peripheral vision of eyeground.

1. Infrared ray
Infrared is one of the many invisible rays of the sun, discovered by german scientist huxlel in 1800, also known as infrared thermal radiation, who split the sun with a prism and placed thermometers on the various colored bands in an attempt to measure the heating effect of the various colored lights. It was found that the thermometer located outside the red light warmed up the fastest. It was thus concluded that: in the solar spectrum, there must be invisible light outside the red, which is infrared. And may also serve as a vehicle for transmissions. The wavelength of infrared rays in the solar spectrum is larger than that of visible rays, and the wavelength is 0.75-1000 mu m. The infrared ray can be divided into three parts, namely near infrared ray, and the wavelength is 0.75-1.50 mu m; the medium infrared ray has the wavelength of 1.50-6.0 μm; far infrared ray with wavelength of 6.0-l 000 micron.
2. Physical properties of infrared ray:
the segment of the spectrum with wavelengths from 0.76 to 400 microns is called infrared, which is invisible. All substances above absolute zero (-273 c) can produce infrared radiation. Modern physics is called heat rays.
3. Medical infrared rays can be divided into two categories: near infrared rays and far infrared rays.
Near infrared rays or short-wave infrared rays with the wavelength of 0.76-1.5 microns penetrate deeper into human tissues by about 5-10 mm; far infrared rays or long-wave infrared rays with the wavelength of 1.5-400 microns are mostly absorbed by surface skin, and the depth of penetrating tissues is less than 2 mm.
4. Physiological and therapeutic effects of infrared light:
reflection and absorption of infrared rays by the human body
After the infrared rays irradiate the body surface, one part is reflected, and the other part is absorbed by the skin. The degree of infrared reflection by the skin is related to the condition of pigmentation, and non-pigmented skin reflects about 60% of its energy when irradiated with infrared radiation having a wavelength of 0.9 microns; whereas pigmented skin reflects about 40% of its energy. When long-wave infrared rays (with the wavelength of more than 1.5 microns) are irradiated, most of the long-wave infrared rays are reflected and absorbed by superficial skin tissues, and the depth of penetrating the skin reaches only 0.05-2 millimeters, so that the long-wave infrared rays only can act on the superficial tissues of the skin; the short wave infrared ray (within 1.5 micron wavelength) and red light near infrared ray penetrate into tissue to the deepest depth of 10 mm, and can act directly on blood vessel, lymphatic vessel, nerve ending and other subcutaneous tissue of skin.
5. Therapeutic action of infrared rays
The basis of the therapeutic effect of infrared is the warming effect. Under the irradiation of infrared rays, the temperature of tissues rises, blood capillaries expand, the blood flow is accelerated, the metabolism of substances is enhanced, and the vitality and the regeneration capability of tissue cells are improved. When the infrared ray is used for treating chronic inflammation, the blood circulation is improved, the phagocytic function of cells is increased, the swelling is eliminated, and the inflammation dissipation is promoted. The infrared ray can reduce excitability of nervous system, and has effects of relieving pain, relieving spasm of striated muscle and smooth muscle, and promoting recovery of nerve function. When used for treating chronic infectious wounds and chronic ulcers, the composition improves tissue nutrition, eliminates granuloma edema, promotes granulation growth and accelerates wound healing. The infrared radiation has the function of reducing exudation of burn wound surface. Infrared is also often used to treat bruises and contusions, promote tissue swelling and hematoma dissipation, alleviate post-operative adhesions, promote scar softening, alleviate scar contractures, and the like.
6. Damage of near infrared ray to eyes
(Zhang Xiao, et al. research progress on eye injury by visible light and near Infrared ray [ J ] Chinese occupational medicine, 2013,40(01): 77-79.)
The damage of the near infrared rays to the eye is mainly a thermal damage effect. The infrared rays propagate by vibration, and are absorbed by the tissue to increase molecular motion, causing a warming effect. According to the characteristic of eyeball tissue to selectively absorb near infrared rays, thermal damage can be divided into corneal damage, lens damage and retinal damage.
6.1. Near infrared rays having a longer wavelength of corneal damage caused by infrared rays cannot penetrate the cornea but are absorbed by the cornea because of their lower energy. The near infrared ray can burn the cornea. The nerve endings of the cornea are very sensitive to temperature, and when the surface of the cornea absorbs 100kW/m2 infrared radiation, the temperature is approximately 45 ℃, and human eyes can generate pain within 1s [ 5 ]. Therefore, acute burns of infrared rays are rarely seen in the cornea, and even if a strong infrared ray source is encountered, the damage of the cornea is mostly limited to the surface, and the cornea can be recovered without permanent damage.
6.2. Near infrared rays with crystalline lens damage wavelengths of 800-1200 nm and 1400-1600 nm caused by the near infrared rays can penetrate through the cornea to enter the eyeball, and aqueous humor, the iris, the crystalline lens and the vitreous body absorb a part of the near infrared rays, so that the temperature of the crystalline lens of the eye is increased, turbidity with different degrees appears in the center, and cataract is caused in serious cases [ 21 ]. Epidemiological investigation of infrared cataract the damage effect was first found in glass blowing workers [ 22 ], and in the near future, infrared cataract was also found in steel smelting workers, workers near high-heat furnaces, welders, and other workers. In 1984, LYDAHL et al [ 23 ] conducted a number of investigations on glassware and iron workers, and carried out individual IR exposure dose evaluations and lens examinations on 209 glassware and 298 control groups aged > 50 years and occupational exposure age > 20 years, and it was shown that occupational IR exposure increased the risk of developing cataract, and that IR exposure in the same age group accelerated the progression of lens aging by a risk of less than 0.7 of cataract by 2.5 times that in the non-contact group (95% confidence interval 1.4, 4.4). The results of the investigation of the crystalline lens of 1210 steel workers by DOROZHKIN et al [ 24 ] show that the occurrence of cataract is directly related to the working age, the posterior capsule of the crystalline lens can be turbid for workers with the working age of 10-15 years, and the brown change of the crystalline lens nucleus and the front capsule can be seen for workers with the working age of more than 15 years. 21084 workers working at high temperature were examined for their crystalline lenses by Huqin et al [ 25 ], and found that the crystalline lenses of 25 workers had thermal cataract, and among the workers with altered crystalline lenses, the incidence of the smelting work was high, the degree of clouding was also high, and the incidence of the disease was high among the elderly. The research of Hades, Hades and the like [ 26 ] finds that the prevalence rate of infrared cataract of workers in an infrared radiation exposure group is obviously higher than that of a control group (P is less than 0.01), the detection rate of lenticular opacity increases along with the increase of the exposure working age of infrared radiation, and the increase of the groups with the working age of more than 15 years is quicker.
6.3. The large dose of short-wave near infrared ray irradiation of retina injury caused by near infrared rays can penetrate through refractive interstitium and focus on macula part of retina, so that the tissue temperature of macula part rises rapidly, and flash burn is caused. Mild burns can cause necrosis of pigment epithelium, photoreceptor cells, pigment cytochrome residue, damage to the inner layer of the choroid (microvascular layer), and severe burns can cause damage to the inner layer of the retina, eventually leading to macular degeneration and even perforation. In industrial workplaces, visible light and near-infrared radiation are in very wide contact, such as arc light generated by arc welding operation, strong light generated by electric cutting, light source production stations, high-temperature processing stations and the like. Although some of the stations provide workers with protection from filters and the like, there are still many cases of visual and eye damage caused by visible and near-infrared radiation each year. The health standard related to occupational contact limit values of visible light and near infrared radiation is not issued currently in China, on one hand, the effect and mechanism of eye injury caused by visible light and near infrared are very complex, a plurality of problems which are not clarified exist, further research and discussion are needed, on the other hand, the attention degree of people on the harm of visible light and near infrared radiation is insufficient, and data related to the occupational population contact situation is lacking in China. Therefore, in order to ensure the health of workers and people, on the basis of detecting the damage mechanism of visible light and near infrared radiation eyes, the dose-response relation of the damage is searched, and a large amount of work needs to be completed.
for a long time, closely using eyes → eyestrain of eye muscles → fatigue of eye muscles which are not in place for adjustment → collection is not in place → an object image falls on the posterior side of retina → local stretching of the peripheral visual field of the eyeground → local deformation occurs when a large visual angle object such as a frame and a window frame of a peep door is seen → the brain does not allow the false alarm phenomenon to appear → the cornea is pulled through the eye muscles → the eyeground deformation defect is compensated → the deformation of the frame and the window frame of the peep door disappears; however, when the human eye looks at a small object at a distance → the light is transmitted through the deformed cornea → refracted into the central fovea of the retina without deformation → a phenomenon of a front-back ghost occurs; the brain does not tolerate ghosting → again the cornea is pulled back. Moreover, the adjustment speed never keeps up with the switching speed of the distance view and the near view, so that the vision fatigue of the astigmatic person is heavy.
The instrument structure characteristics related to seven kinds of bionic visual training and the main functions thereof are as follows:
1. all-round eye yoga motion:
the method is natural: all animals are afraid of being eaten by other animals, namely the eyeball can stretch everywhere ceaselessly → through movement → promoting blood circulation to remove blood stasis → good blood circulation → no visual fatigue → no pseudomyopia → no more true myopia and the like. It can be used for improving eyesight by reversing the above steps.
The instrument is characterized in that: the visual mark points are located near the limit of the visual range of human eyes, and the visual mark points are completed by the luminous viewpoint control unit.
The method has the unique functions that: the omnibearing eye yoga movement utilizes the characteristic that human eyes tend to be bright to drive eyeballs to do omnibearing eyeball yoga movement close to the movement limit. The eyeground peripheral visual field is stimulated while the extraocular muscles are fully exercised, the eyeball blood circulation can be fundamentally improved, and the physiological function of rapidly repairing the sick eyeball is enhanced.
② has effects in improving extraocular muscle function, improving searching ability, assembling ability and locating ability of eyeball, balancing extraocular muscle, improving external causes of strabismus and astigmatism, and improving extraocular muscle asthenopia.
③ when peripheral light spots are found, the diameter of equator is enlarged, and the length of axis of eye is shortened, when the peripheral light spots are approached, the blood circulation of far and near peripheral visual fields across the part is improved, and the power of myopia, hyperopia, astigmatism and emmetropia is formed.
2. Visual system five-linkage binocular imaging:
the method is natural: all animals were eyes-on-the-fly and eyes-on-the-fly, especially the best-sighted birds (human experts require static eyes: no ability to walk to read books, no ability to sit in a car to read books): dynamic eyes → fast moving far and near → fast changing visual angle → strong adjusting ability of visual system → the object image can always fall on the retina.
The instrument is characterized in that: the luminous viewpoints observed by the two eyes with parallel visual axes are all small-view luminous viewpoints consisting of hundreds of thousands of tiny luminous viewpoints, and the luminous viewpoints observed by the two eyes with a set consists of large-view luminous viewpoints.
The method has the unique functions that: compared with the traditional three-linkage binocular imaging, the visual five-linkage binocular imaging has the advantages that visual angle change is increased, and two links of comparison and judgment of the brain and experience data are increased. Therefore, the adjustment of ciliary muscle and the size change of pupil can be effectively driven (the traditional triple action has no visual angle change, and the brain has proper feeling and does not adjust when performing comparison judgment).
② can relieve eye fatigue caused by intraocular muscle, relieve sclera stretching pressure, and eliminate distending pain caused by scleral stretching
3. Peripheral visual field stimulation training:
the method is natural: wild animals are afraid of being eaten by other animals → peripheral vision is very well used → peripheral vision blood circulation is good → scleral tensile tension is strong (or scleral developmental activity is strong) → promotion of emmetropia → maintenance of good eye condition.
The instrument is characterized in that: the luminous visual point of the peripheral visual field is arranged at the edge of the movement limit of the eyeball, if the eyeball always looks straight ahead and is sensed by afterglow, the peripheral luminous visual point flickers and rotates, and at the moment, the object image of the peripheral visual field just falls on the outer side of the equator of the eyeball, and the object image is just the weakest part of the sclera in the document.
The method has the unique functions that: peripheral visual field stimulation training for stimulating the weakest part of the blood circulation in the peripheral visual field of the eyeground
⑴ in the case of myopia, the myopia,
① from the optical angle, the equator diameter is enlarged to shorten the length of the eye axis, and the problem that the length of the eye axis in modern medicine can not be shortened is solved;
② stimulating peripheral vision of ocular fundus, and allowing peripheral vision cells to participate in work, and improving blood circulation of sclera in peripheral vision of ocular fundus, increasing tensile tension of sclera, and shortening axial length of eye gradually;
⑵ for hypermetropia, it can stimulate the peripheral vision of ocular fundus, improve the blood circulation angle of peripheral vision, enhance the development activity of sclera, and promote the development of axial emmetropia;
⑶ for astigmatism and strabismus, the part of the fundus oculi stretched can be gradually normal, and the local cause of astigmatism and strabismus can be eliminated.
4. Training visual acuity,
The method is natural: the visual acuity of the eagle was best in all animals-the eagle could be seen from three kilometers of high above air → exactly what chicks pecked on the ground, running rats and hares.
The instrument is characterized in that: light-transmitting cover capable of forming clear and distinguishable secondary substructure on luminous viewpoint
The method has the unique functions that: the unique visual acuity training is beneficial to the improvement of the resolving power of a user for watching the visual target with a small visual angle. Meanwhile, according to the lens imaging principle, an object image after refraction of numerous tiny viewpoints in the light-emitting viewpoints of the eye yoga vision enhancer also falls behind the retina, but the focal depth is super-prolonged according to the focal depth principle because the viewpoints are small, the incident angle is tiny, and the light cone is fine, so that the image imaged behind the retina can be clearly seen on the retina without lengthening the eye axis. Therefore, the phenomenon that the eye axis is stretched backwards by the luminous viewpoint with large visual angle of the traditional therapeutic apparatus, which is worried by the qualified ophthalmologist, can not be generated.
5. Super fine eyesight training:
the method is natural: before the birds land, the birds inspect a plurality of targets and simultaneously observe whether the plurality of targets on the ground are abnormal → force a plurality of fine visual cells on the eyeground to participate in the work.
The instrument is characterized in that: light-transmitting cover capable of forming clear and distinguishable secondary substructure on luminous viewpoint
The method has the unique functions that: in the ultra-fine eyesight training, each luminous viewpoint in the eye yoga eyesight improving instrument consists of hundreds of thousands of tiny luminous viewpoints. Therefore, the luminous viewpoint in the instrument can simultaneously activate hundreds of optic cells and optic nerve cells every time the luminous viewpoint flickers.
For the amblyopia patient, the training can efficiently activate the visual cells and the optic nerve cells, and can avoid the complex training of grating, optical brushing, back image, family fine eyesight training and the like. Simultaneously, super meticulous training still can assist other training raising the efficiency:
for example, ① can be used for assisting peripheral visual field stimulation training to increase the strength of shortening the axis of eyes by hundreds times, ② can be used for assisting eyes to flicker respectively, and the ability of eye-brain communication can be enhanced by hundreds times.
6. And (3) carrying out flicker training on two eyes respectively:
the method is natural: the two eyes of the animals are respectively used: to protect natural enemies → animals develop a habit of using two eyes separately → this habit is favorable for the fusion of left and right brains → fusion of both eyes → better stereoscopic vision.
The instrument is characterized in that: the device is completed by the instrument double-window luminous viewpoint setting and luminous viewpoint control unit.
The method has the unique functions that:
the luminous viewpoints of the left eye and the right eye are respectively subjected to flicker training, so that the chances and the abilities of the affected eye or the weak eye to participate in training, vision and vision recovery can be increased.
Meanwhile, in the process that the left and right eye luminous viewpoints alternately flicker, the visual residual of the healthy eye can adjust the visual desire of the weak eye, which is beneficial to getting through the visual passage of the weak eye, enhancing the eye-brain communication capacity of the weak eye, being beneficial to the rapid improvement of the vision of the weak eye, and being beneficial to the compensation capacity of the left and right brains and the fusion capacity of the two eyes.
7. Training with adjustable luminance of two eyes:
the method is natural: the two eyes of the animals are respectively used: to protect natural enemies → animals develop a habit of using two eyes separately → this habit is favorable for the fusion of left and right brains → fusion of both eyes → better stereoscopic vision.
The instrument is characterized in that: the device is completed by the instrument double-window luminous viewpoint setting and luminous viewpoint control unit.
The method has the unique functions that: the brightness of two eyes can be respectively adjusted for training, one eye of a normal person is a dominant eye, the other eye of the normal person is an adjunctive eye, and the training is not to mention the patient with the ametropia. The traditional instrument has two windows with the same brightness and can be trained simultaneously, so that good eyes actively participate, weak eyes passively follow or even do not follow, and further, the refractive error is more and more serious.
The brightness of the luminous viewpoints of the left eye and the right eye is respectively adjustable, and the program for increasing the training strength of the amblyopia is started while the brightness in the amblyopia window is increased, so that the amblyopia training eye becomes the dominant eye, the rapid improvement of the amblyopia vision is facilitated, the degree difference between two eyes is facilitated to be gradually reduced, and the refractive error is facilitated to be gradually eliminated.
