Description

Title of invention: Method and apparatus for reducing eye strain

The present invention relates to the field of vision care and treatment instrument and kaleidoscope in ophthalmology, in particular to a visual physiology rehabilitation instrument for the physiological and physical treatment of myopia, amblyopia, asthenopia, and presbyopia. Background of the invention

Most of the kaleidoscopes that were invented by the public more than a hundred years ago were mostly equipped with reflectors and colored fragments in the body. Rotate the tube to view different images. The inventor has published a "musical electronic kaleidoscope" with Chinese patent number ZL89215916.2., Which replaces colored broken glass and plastic fragments with electronic circuits and light emitting elements. When the light emitting device emits light, an electronic color picture can be viewed. The inventor also announced the "electronic kaleidoscope" of Chinese patent numbers ZL94202550. 4 and ZL002226140. 5, which is composed of a light-emitting board, a mirror group, a control circuit and a lens. The flickering light and color conversion generated on the light-emitting board, Through the reflection of the mirror and the convergent transmission of the lens, a color picture that changes and flashes on the screen can be produced, becoming a modern kaleidoscope and decorative lantern. In addition, the present inventors have also published "Electronic Vientiane Lamps" with Chinese patent numbers ZL90208076. 8 and ZL00226825. 6. However, the electronic kaleidoscope, electronic kaleidoscope lamp, and electronic omnidirectional lamp are only used as a kind of entertainment toys and lighting.

Amblyopia is a serious disease that impedes children's visual development and cannot be corrected with optician methods. At present, there are many methods for preventing and treating amblyopia. One of the more ideal methods is to use the principle of red light flicker to exercise the visual cortex center of the amblyopic eye, so as to achieve the purpose of treatment. Such as: Chinese patents ZL86200467, ZL88217622, ZL90202156, etc., the treatment basis is mainly based on the cone-shaped cells in the retinal macular region are sensitive to light with a wavelength of 600-680nm (nanometer), and through light stimulation, the frequency of sensory penetration and critical fusion is increased to achieve Purpose of exercise and vision improvement. However, the theoretical basis and methods of treatment of all these instruments have ignored the existence of different types of color visual sensors in the human eye. Modern visual electrophysiology and color vision theory prove that: There are three types of cone cells in the human body, and their absorption peaks of the spectrum are 570-590nm (Nano Spring), 530 565nm, and 430-460ηπι, that is, the peak wavelengths are respectively The light of the human body is most sensitive and exciting; at the same time, the rod cells of the human body are dark vision, which is sensitive to light and dark changes, and is more suitable for short-wavelength light than visual cells. Therefore, the alternately changing multiple spectra can also be started separately. To excite and exercise the effect of rod cells; modern visual electrophysiology and color vision theory also show that: vision has an opposite mechanism to color. Under the retina The response of ganglion cells and lateral knee nucleus cell receptive fields to color light can have four mutually opposing color cells. The first type of cell has an excitatory effect on the red light of 620-680 and green light with a wavelength of 530-565 ηπ Produces an inhibitory effect. The second cell acts in the opposite way, that is, the red light does not inhibit it, but the green light excites it. The third cell is a 430-460nm blue light pair. It plays a suppressing role, yellow light with a wavelength of about 570 590 excites it, and a fourth kind of thin bag has the opposite effect on these wavelengths, that is, yellow light suppresses and blue light excites. In addition, according to the research results of visual electrophysiology, the visual show's iShow power generation level (VEP) is also related to the intensity and intensity change of light stimulus, frequency and frequency change, and flash image and image change. The experiments show that: the evoked potential response caused by light of varying intensity and frequency is greater than the evoked potential response under fixed light intensity and fixed frequency; the evoked potential response caused by flashing graphic stimulation is greater than the evoked potential response of simple uniform brightness stimulus It should be noted that the evoked potential response of the flash change pattern stimulus is greater than the evoked potential response of the flash pattern alone, and the evoked potential response of the larger graphic scenario is greater than the evoked response of the small graphical scenario. The above-mentioned various treatment instruments, because most of them use simple oscillating pulse circuits, the flicker frequency is fixed and single; the flickering light intensity cannot be automatically changed, and most of the methods are single or two light sources. Uniform stimulus and small contrast of graphic scenes; due to method limitations, the wavelength range of the light source used by it is deviated from the most sensitive and excited peak center region of the human retina cone cells. Compared with the research achievements of modern visual electrophysiology, these are outdated and inadequate, thus preventing further improvement of the therapeutic effect. In addition, due to the limitations of the structure and circuit design of the addictive instrument, the operation principle and method are complicated, which brings many inconveniences and difficulties to children and affects the effect of actual treatment.

The inventors have published Chinese patent numbers ZL94212912 and ZL982331800, "Amblyopia Healthcare Electronic Kaleidoscope" and "Amblyopia Healthcare Therapy Device" designed using the principle of visual biological spectrum scintillation. They use red, green or red, green and blue spectrums respectively. The light source is used as an imaging and irradiation light source, and the electronic flash is used to realize the frequency conversion, spectral conversion and image conversion of light flashes. It stimulates three different types of cone cells and brain cortex that are sensitive to exercise, and improves the visual evoked potential of the brain. , Increase the frequency of sensory input and critical fusion, so as to achieve the purpose of improving the treatment effect. The instrument technically solves the problems of lack of visual image stimulation exercise and single spectrum conversion of general amblyopia, and provides an effective treatment and protection device for the prevention and treatment of amblyopia entering the home. However, because the instrument uses the traditional kaleidoscope imaging principle and structure, it produces a three-dimensional image of space, that is, the images viewed are not in the same focal plane, so there is a lack of visual fixation focus and visual fixation center. It is difficult to concentrate, which affects the viewing and gaze effects used by patients, which limits the actual curative effect; at the same time, the device uses only two or three types of vision The stimulating exercise of sensory biological light, neglecting the exercise of optic ganglion cells and lateral geniculate nucleus cells, has limited effect on the exercise of visual conduction and visual cortex center, and also affects its treatment effect. In addition, since ametropic amblyopia and ametropic amblyopia account for a large proportion of patients with amblyopia, in such beneficiaries, refractive adjustment disorders and visual perception disorders coexist and restrict each other, and the above-mentioned instruments are mainly Aiming at training the optic nerve and improving the ability of visual perception, the lack of a more direct effect on the exercise and the improvement of the eye's regulating function also affects the effect of its use and treatment, and also limits its scope of application.

Myopia is also a serious disease that seriously impedes the growth and development of children. Most patients with myopia are the result of the evolution and development of regulatory disorders caused by visual fatigue and accommodative myopia, exercise and enhance the regulating function of the eye, and eliminate eye lashes in time. Tension and spasm of the muscles of the shape and eye muscles are currently the main methods of treating and preventing myopia. For example, Chinese patents ZL92101 546.1 and ZL972 08881. 4 use the optotype image to regularly make periodic back-and-forth movements in front of the user's eyes, exercise the ciliary muscles and the adjustment system, and relieve the spasm of the ciliary muscles of the eyes. And adjust tension to eliminate visual fatigue and restore normal vision. The human eye and visual system are composed of two parts: the visual adjustment system and the visual perception system, just as the camera is composed of the focusing part and the negative part. The quality of vision depends on whether the two parts of the system are intact at the same time. They promote and restrict each other in the visual process. In the actual situation, if the lens of the eye and the ciliary muscle of the eye appear to be dysregulated, vision fatigue, regulatory myopia or hyperopia will occur, and if the developmental defects of the retinal nerve and the central cerebral cortex of the brain cause amblyopia. In addition, the short-sightedness caused by short-sightedness, far-sightedness, and eye regulation can also lead to the occurrence of amblyopia, and the occurrence of amblyopia can also cause the problem of regulation disorder. Therefore, to have good vision, it is necessary to keep both parts of the vision system intact and normal at the same time. The above methods for preventing and controlling the instruments all start with the adjustment part of the exercise visual system. The visual target images of the instruments are fixed slideshow pictures. The background light sources are incandescent lights. These lack direct effects on the visual perception system and exercise. There is more lack of irradiation and massage of visual biological light, so its method is incomplete, which limits the improvement of the efficacy and the expansion of the scope of application.

The present invention is described in further detail below with reference to the drawings.

A visual physiological rehabilitation method proposed by the present invention uses a variety of visual biological spectra sensitive to human retinal cells to generate a target image with planar fixation properties and fixation focus, and by viewing the transformed light t 昝, transformed frequency, transformed image, and transformed image Visual distance target image, Excited inhibition of cone cells, rod cells, optic ganglion cells and lateral geniculate nucleus cells, exercise the visual cortex center of the brain, induce visual biological feedback and physiological adjustment, and release eye ciliary muscle and eye muscle group The tension and spasm of the eye can eliminate visual fatigue, improve the visual resolution ability and the critical fusion frequency of vision, improve the visual conduction function, visual perception function and visual adjustment function, and achieve the purpose of restoring normal vision. Thus, the effect of treatment and health care is further improved and improved; at the same time, microcomputer control technology is applied to realize the automation of the treatment process and the use operation, reduce the use operation requirements of patients, and make it easier to popularize and apply.

Using microcomputer control technology, through the treatment program programming and microcomputer control, the spectral conversion, frequency conversion, image conversion and timing, positioning transmission of the optotype image are realized, which plays a role of regularly changing the visual distance of light, frequency, image and image .

As shown in FIGS. 1 and 2, the optotype image is a light intensity, frequency, Spectral and pattern-changeable images. The light emitting device includes a plurality of groups of light emitting devices, which can generate light with a peak wavelength of approximately 620-680 μm (nano), 530-570ηηκ 430-475nm, and 575-590. The optotype image can be issued in other structural forms. The requirement is to generate a optotype image with a flat fixation property. The optotype image is clear, the image scene is large, and it can implement spectral transformation, frequency transformation, image transformation, and visual distance transformation of the image. .

The process and method of visual physiological rehabilitation treatment include the following steps and contents: a. Regularly changing the light and light flash frequency of the optotype image; b. Regularly changing the spectral conversion order and conversion frequency of the optotype image; G. Musically controlling the optotype image The order and frequency of spectral conversion; d. Regularly transform the visual target image and the visual distance of the visual target image.

In the step a, the microcomputer (not shown) controls the luminous body to convert the peak wavelengths to about 430-475nm (blue), 620-680nm (red), 530-570 training (edge color), and 575-590 Let the spectrum of (yellow) flicker separately, and the frequency range of light flicker varies from about 0.5 to 25Hz (Hz). Time is 1-5 minutes. For example: first convert to blue light, and flash for 30 seconds at a frequency of 0.5 Hz, and then convert to red light, edge color light and yellow light in turn, and flash at the same frequency and time; then follow the same method and separately Flashes at 2Hz, 4Hz, 8Hz, 25Hz, etc. for 30 seconds. Through these processes, on the one hand, three types of cone and rod cells can be excited, inhibited, and stimulated to exercise the visual cortex center of the brain.On the other hand, the use of different light flash frequencies can reduce visual adaptability. Exercise increases the critical fusion frequency of vision. At the same time, in the process of light flash, due to the intensity and spectrum of light rhythm changes, visual biological feedback and visual physiological adjustment can be directly discussed, and the eye's ciliary muscle, pupil regulating muscle, and Other eye muscle groups. It is best to change the flash frequency from low to high, so that the vision gradually adapts and improves. In order to improve the time efficiency of effective treatment and tempering, the design upper limit value of the light flash frequency is generally slightly lower or close to the visual critical fusion frequency value of the normal eye.

The step b is that the microcomputer controls the luminescence to change the spectral conversion order according to the following ways: red-green-blue, blue → red, red → green, blue → yellow, and the frequency change of the light i 昝 conversion The range is about 0.5 to 25 Hz. Timed 1-5 minutes. The red, green, and blue light transforms can be used to stimulate and stimulate the red, optic, and blue cone cells in the cone cells. Through the blue → red spectrum flicker and conversion, the cones can be suppressed and excited. Cells and rod cells; through the red edge color, blue-yellow two spectral transformation and flicker, can make the optic ganglion cells and epiphyseal 'knee-shaped nucleus cells produce the corresponding on-off response, further training the visual conduction function and Feel the function. The combination of spectral conversions should follow the above-mentioned permutation 'combination, and the frequency of spectral conversions can gradually change from low to high.

s The step G is: controlling the music playback by a microcomputer and synchronously controlling the light of the luminous body by the rhythm or frequency of the light ^ "conversion and conversion frequency and light flash frequency, the range of the music control frequency is about Q. 5- 30Hz, The sequence of the spectrum conversion is continuously cycled from red ^→ green → blue. Timing 1-5 minutes. For example: While playing music, use the rhythm or music of the music to control the spectrum. Red → green-blue is continuously converted and cycled. The frequency of conversion is controlled by the rhythm of the music or the frequency of musical notes. The frequency of change of the music rhythm can be used to synchronize the conversion frequency of the light, and the frequency of light flicker can be controlled by the change of the music rhythm to synchronize with it. Use it alternately, which can further enrich the image change and frequency change. Since the music rhythm is compatible with the biological rhythm of the human body, its frequency change is also very rich. Through audiovisual synchronization, it can further enrich the visual biological spectrum of light and stimulate the exercise. Sympathetic nerves in the human body increase the frequency of visual biological light on visual cells and the central cortex of the brain Refining effect, can also improve patient viewing gaze and therapeutic interest, improve the therapeutic effect. In order to increase the contrast optotype image scene, a plurality of sets may be respectively the same light "i Lu luminous body, it will give a richer image.

The step d is controlled by the microcomputer and the electromechanical 21, so that the visual target and the visual target image are regularly reciprocated and transformed between the farthest point and the nearest point, and each reciprocating movement transforms one or more spectra to work. Time 1-5 minutes. For example: First, make the luminous body produce a red-spectrum image on the optotype 1 0. The optotype starts to move slowly from the farthest point (that is, the position of the far point equivalent to the emmetropic eye) to the nearest point (equivalent to the object in front of the emmeteor 10 eyes). The visual distance is about 20 centimeters), and then the world moves slowly to the farthest point to complete a reciprocating movement; and then the reciprocating movements are performed with the spectrums of green, blue, and yellow, respectively; then red + green, blue + yellow, and blue + The combined light of red, blue + green, green + yellow, etc. transforms and reciprocates. Using these methods, one can exercise the ciliary muscles and eye muscle groups through regular distance changes of the target image, eliminate fatigue and spasm of the ciliary muscles and eye muscle groups, restore the eye's regulating function, and enrich the spectral changes. It can stimulate the exercise of visual cells and nerves at the same time, and improve the visual sensibility at the same time, and can play the role of training the visual perception system and the visual adjustment system at the same time. Since the target image at the far point of the emmetropic eye is not adjusted, the starting position and non-moving working position of the target 10 are positive ^ L, the far point position of the eye, which is the farthest point described above. Point location.

The methods, steps and contents of the above-mentioned visual physiological rehabilitation, their order and treatment time can be changed according to different force diseases. For example, for the treatment of amblyopia, the steps and contents of a, b, and G can be appropriately increased, and the treatment time can be relatively longer, while for the treatment of visual fatigue and accommodative myopia, the treatment and treatment time of step d can be appropriately increased.

The visual physiological rehabilitation method proposed by the present invention can be implemented by the following visual and physiological rehabilitation apparatus: As shown in FIG. 1, the present invention includes a housing 1, a viewing tube 2, a target imaging device 6, a target driving device 15, a power source. 7, The microcomputer controller 5 and the sounder 8, wherein the visual target imaging device 6 is sequentially provided with a visual target 10, an objective lens 1 and a reflector group 12 and a light source group 13 along the center line thereof, and the viewing tube 1 The eyepiece 9 is installed, and its center line coincides with the sight target 10 and the objective lens 11. The light source group 13 is a plurality of groups with peak wavelengths of 620-680nm (nano), 530-570ηηκ 430-475ηηι, and 575-590nm. A light emitting device, the microcomputer controller 5 is provided with a plurality of sets of spectral frequency conversion, light intensity conversion, image conversion, visual distance conversion and visual critical fusion frequency, and a plurality of fixed frequency conversion and audio conversion treatment programs and music programs, The light source group 13 is controlled to generate an image of light intensity, frequency, spectrum and image that changes with the setting of a treatment program or a music program on the visual target 10, and at the same time, the visual target driving device 15 is driven to drive the visual target 10 to generate timing, positioning transmission and movement, and change regularly. Visual distance, and play music synchronously.

The visual physiological rehabilitation method provided by the present invention can also be implemented by the following visual physiological rehabilitation apparatus: As shown in FIG. 2, a visual physiological rehabilitation apparatus includes a housing 1, a viewing tube 2, an optotype imaging device 6, and an optotype driving device. 15, a power source 7, a controller 5, and a sounder 8, wherein the visual target imaging device 6 is sequentially equipped with a visual target 10 and a light source group 13 along its center line, and the viewing tube 1 is equipped with an eyepiece 9, The center line coincides with the visual target 10. The light source group 13 is a plurality of groups of light emitting devices with peak wavelengths of approximately 620-680 (nanometers), 530-570nm, 430-475nm and 575-590nm, respectively. 5 is a ^ drum computer controller. The visual target imaging device 6 in this technical solution adopts a more simple structure. The visual target 10 may be composed of a light source group 13 in which light emitters are arranged, and the light emitter on the light source group 13 is opposite to the eyepiece 9. In order to make the scene contrast of the image larger, multiple groups of illuminants can be used and arranged into geometric figures in order. The light source on the light source group 13 may be composed of a semiconductor light emitting material, such as an LED, or an electrode cold light source material, such as an EL cold light source sheet. This will make the image richer.
