Eye strain relief device

Abstract

Instead of providing intravenous fluids containing various vitamins to alleviate eye strain, this approach focuses on the inherent vitality of plants and offers the healing effects of plant leaves. [Solution] The eye strain reduction device of the present invention is not affected by the weather and utilizes not only sunlight but also indoor lighting to allow the green-yellow light of plants to enter the human eye 24 hours a day, not only during the day but also at night, by using eyeglass frames to hold freshly picked leaves or leaves that have been picked and stored in a household refrigerator. Since the green-yellow light is a medium-wavelength color light in the visible light range, eye strain can be improved.

[0001] The present invention relates to an eye fatigue reducing device.

Background Art

[0002] As disclosed in Patent Document 1, there are disclosed an eye fatigue improving agent for improving eye fatigue (Patent Document 1), an eye drop for improving eye fatigue containing taurine and menthol as an active ingredient, and an eyeglass lens in which a coloring agent is suppressed from detaching from the colored eyeglass lens (Patent Document 3), etc.

[0003] Today, it has been pointed out that due to eye fatigue caused by personal computers, mobile liquid crystal videos, and liquid crystal screens overflowing in the city, and an increase in the wearing of contact lenses, the contrast sensitivity indicating the ability to distinguish subtle differences in brightness, which is one of the visual function evaluation axes, decreases. For example, when walking, it is difficult to recognize the contrast between the road surface and obstacles, which may lead to accidents, and in ball sports, there may be a situation where it becomes difficult to recognize the contrast between the ball and the background. Therefore, the problems of eye fatigue from liquid crystal screens and eye fatigue and difficulty in seeing in contact lens wearers are serious.

Summary of the Invention

[0006] The objective of this invention is not to create an intravenous solution containing various vitamins to improve eye strain, but rather to focus on the vitality and green-yellow light inherent in plants and utilize plant leaves. [Means for solving the problem]

[0007] The objective is to provide a method for improving eye strain by allowing various nutrients contained in plant leaves and green-yellow light in the mid-wavelength range of the audible spectrum to pass through the eye, rather than transmitting light through artificially created colored lenses.

[0008] Furthermore, the present invention transmits light through plant leaves, and this transmitted light is directed into the eye to provide visual stimulation. It also allows for transdermal absorption of green, medium-wavelength frequencies through the skin covering the eyeball, utilizing the vitality of plant leaves to provide a healing effect. [Effects of the Invention]

[0009] Traditional uses of plant leaves include the use of bamboo leaves to wrap dango (rice dumplings), oak leaves to wrap kashiwa mochi (rice cakes wrapped in oak leaves), cherry leaves to wrap sakura mochi (rice cakes wrapped in cherry blossom leaves), and bamboo leaves to wrap mochi sweets and yokan (sweet bean jelly), all of which are considered to have excellent antibacterial properties. In addition, tea leaves such as Japanese tea leaves, mulberry leaf tea, dandelion tea, Aralia elata leaf tea, Houttuynia cordata leaf tea, Eucommia ulmoides leaf tea, shepherd's purse tea, lotus leaf tea, chickweed tea, senna leaf tea, loquat leaf tea, pine leaf tea, mate tea, mugwort tea, coffee leaves, Japanese laurel tea, and bay leaf tea are also known to be used as beverages when brewed, with the expectation of improving one's constitution.

[0010] The present invention's eye strain reduction device utilizes thin leaves that transmit greenish-yellow light, i.e., medium-wavelength colored light, to the eye, stimulating the eye visually. Simultaneously, it is thought that nutrients from the raw plant leaves can be absorbed transdermally through the skin covering the eyeball. Furthermore, the use of thin leaves that transmit green colored light is considered to increase photosynthesis throughout the leaf because sunlight passes through the leaf, reaching the underside of the leaf as well. By using thin leaves that transmit greenish-yellow light, it is possible to absorb colored light in the audible range of the healing spectrum, as well as trace amounts of water transpiration and aroma from the leaves transdermally. Moreover, even without direct sunlight, the plant leaves can absorb a small amount of oxygen transdermally through photosynthesis caused by transpiration. This led to the conclusion that this device can be used to improve eye strain.

[0011] The present invention provides an eye strain relief device that, even without sunlight and regardless of weather or location, allows the eyes and forehead to be exposed to the colored light of plant leaves 24 hours a day, even in rainy weather or at night, by using eyeglass frames with leaves attached, and illuminated by indoor lighting, thereby improving eye strain.

[Figure 8] Wavelength diagram of visualization light rays. [Figure 9] Conditions for the leaves of the plants used in this invention. [Modes for carrying out the invention]

[0013] Figure 1 illustrates the structure of the eyeball. Light (colored light) 1 passing through a leaf passes through a thin, green or yellow leaf 2, and it is hypothesized that the following propagation occurs within the eyeball as the light passes through the leaf 2: The cornea 9 of the eyeball allows light to pass through and refracts it. The iris 13 corresponds to the brown eye in Japanese people, and the black part in the center of the iris 13 is the pupil 3. The iris 13 is located above and below the pupil 3, and medium-wavelength colored light from the plant leaf passes through the lens 4, which thickens and thins like a camera to adjust focus. The function of the iris 13 and pupil 3 is the same as the aperture of a camera, adjusting the amount of light entering the eye. The choroid 20 is rich in blood vessels and nourishes the retina 21. In other words, the retina 21 corresponds to the film of a camera, and the fovea (macula) 6, which is the posterior part, is responsible for seeing. The retina 21 is said to contain approximately 1 million optic nerve fibers throughout the entire eyeball. The part where the optic nerve penetrates the wall of the eyeball is the optic disc 7, and the light transmitted into the eyeball by the cornea 9 is then transmitted to the brain by the optic nerve 8, which in turn transmits information generated in the retina. The usefulness of the eye strain reduction device of the present invention will be confirmed using a human saliva ORP device.

[0014] Next, we will explain each part of the structure diagram of the eyeball in Figure 1. The vitreous humor 5, which makes up the majority of the contents of the eyeball behind the lens 4, is jelly-like and 99% water, and the aqueous humor 10 produced by the ciliary body 16 is drained through Schlemm's canal. The posterior chamber 11 is located between the iris 13 and the lens 4 and is the conjunctiva 12, which produces tears to lubricate the surface of the eye and prevent the entry of foreign objects. The ciliary zonule 15 supports the lens 4, and the ciliary zonule muscles 16 adjust the thickness of the lens 4 for viewing distant or near objects. The thin membrane covering the inner side of the eyelid 14 is the conjunctiva 12. The extraocular muscles 18 are responsible for turning the eye up, down, left, and right, and there is the lacrimal gland, which is the site of tear secretion, and the eyelashes prevent dust from hitting the cornea 9 and conjunctiva 12. It is well known that the eyeball, in conjunction with the brain, is responsible for confirming an object and reflecting its effects on both mental and physical states.

[0015] Figure 2 is an example of a perspective view from the left of a spectacle frame for storing and using the leaves of a plant according to an embodiment of the present invention. Light (colored light) 1 passing through the leaves stored in the spectacle frame passes through the green or yellow leaves of the foliage, and the light transmitted into the eyeball by the cornea of the eyeball is transmitted by the optic nerve to convey the information generated on the retina to the brain, which was explained in FIG. 1. In FIG. 2, the means for attaching the leaves to the human face is a spectacle frame 62 for storing the leaves of the plant, without pressing the leaves with tape and sticking them to the face or pressing them by hand. As shown in FIG. 3, the leaves 2 are stored at the bottom 58 of the spectacle frame 62 so that they do not fall down. The frame material of this spectacle frame is either a metal-based or a plastic-based one, and the material is not limited. And the design and shape of the spectacle frame 62 are not limited to the example figure. The part corresponding to the normal spectacle lens is provided with a rounded rectangle 64 that is hollowed out so that the leaves touch the skin so that the light transmitted through the leaves of the plant is incident on the skin of the eyeball part, and the leaves can be inserted from above into the opening 60. Thereby, the leaf 2 is held in front of a person's eyes. A nose pad 63 is provided to support the glasses with the nose, a temple (arm) 65 is provided to fit the glasses, and a tip cell 61 that touches behind the ear is provided. Thereby, the glasses are used for storing the leaves of the plant to rest the eyes during breaks and improve eye fatigue. The focus of the present invention is to use a spectacle frame for storing and using leaves to transmit the green and yellow colored light of the leaves of the plant to the eyeball, and the fragrance of the leaves. Since the spectacle frame has a shape of a rounded rectangle that is hollowed out 64, through the nose (smell), and furthermore, the components contained in the leaves can be transdermally absorbed by the optic nerve in the eyeball through the skin by the transpiration action of a small amount of moisture. Also, it is known that the area of the Yintang in the center between the eyebrows has been a pressure point for eye fatigue, headache, rhinitis, and empyema since ancient times. The present inventors focused on whether the leaves of the plant could obtain the benefits of oxygen release by photosynthesis of colored light transmission through transdermal absorption, and thought that using these characteristics would lead to the improvement of eye fatigue.

[0016] Figure 3 is an example diagram showing the eyeglass frame for storing plant leaves according to the present invention. The bottom 58 of the eyeglass frame 62 can store plant leaves 2 and is designed to prevent them from falling out. The fragrance of the plant leaves 2 can be inhaled through the nose (olfactory sense) 77. This is because, as the plant leaves receive light, the oxygen-contributing effect of photosynthesis through transpiration can also be expected to be absorbed transdermally. The forehead 74 of the face where the eyeglass frame is worn is the hair 79 and the mouth 78. The space between the eyebrows 75 is called the point of concentration of vital energy, and is an acupressure point for improving eye strain, headaches, rhinitis, and sinusitis. In yoga, it is also called the third eye, which is positioned as a chakra, and is considered to be the place that governs intuition, insight, and spirituality. When the plant leaves touch this space between the eyebrows, the components contained in the leaves can be absorbed transdermally through the skin. Furthermore, it is thought that they can be absorbed transdermally by the optic nerve in the eyeball. The tip 61 that touches behind the ear is covered with hair 79 and rests on the ear. The present invention aims to improve eye strain by allowing light transmitted through plant leaves 2 to enter the eyes or between the eyebrows through the mouth 78, without the use of medicine or food / drink.

[0017] Figure 4 is a configuration diagram of a human saliva ORP measuring device that visualizes the effects of the present invention. The human saliva ORP measuring device 36 is provided with three measurement BOXes 42 having the same configuration between two electrodes, namely a reference electrode 32 and a working electrode 26. The enlarged view of the nozzle shows the configuration between the reference electrode 32 and the working electrode 26 therein. Two paired reference electrodes (silver-silver chloride electrodes) 32 and a working electrode (platinum electrode or pure gold electrode) 26 calculate the electrolyte concentration of all saliva components and the activity ratio of the oxidized form and the reduced form, and measure the potential difference between oxidation and reduction. A KCl solution 34 that allows the plus-minus electron transfer exchange of the saliva ORP between the reference electrode (silver-silver chloride) 32 opposed to the saliva 23 impregnated in the cotton swab and the liquid junction part 30 that becomes the contact point of the cotton swab 23 impregnated with saliva and wet by the capillary action causes a minute amount of the KCl solution 34 to be drawn into the KCl solution 34 and the cotton part 23 impregnated with saliva. Through the KCl solution 34 at the two electrodes of the reference electrode 32 and the working electrode 26, plus-minus electron transfer exchange is performed, the oxidation-reduction potential (mV) potential difference is calculated, and the measurement result is displayed in liquid crystal at 39. A tank lid 33 for storing the KCl solution, a shaft rod 22 of the cotton swab for impregnating saliva, a cotton part 23 of the cotton swab impregnated with saliva, a sample tank base part 24 into which the cotton swab impregnated with saliva is inserted, a part 25 where the head part of the saliva-impregnated cotton swab 23 contacts the working electrode 26, and the working electrode 26 is fixedly adhered to the bottom of the sample tank 29. A part 27 where the working electrode 26 and the lead wire 28 are adhered and connected, a part 31 where the reference electrode (silver-silver chloride) 32 and the lead wire 28 are adhered and connected, and an oxidation-reduction potential mV measurement unit 35 that calculates the potential difference by the plus-minus electron transfer exchange between the reference electrode 32 and the working electrode 26 through the KCl solution, a measurement start button 38, a measurement result print button 37, a liquid crystal unit 39 that displays the measurement result by the oxidation-reduction potential mV measurement unit 35 that calculates the potential difference, a liquid crystal unit 40 for displaying the AD and time, a thermal print 41 of the measurement result, and the configuration between the reference electrode and the working electrode is provided in three measurement BOXes 42.

[0018] Figure 5 is a numerical chart of the health status based on the human saliva ORP index, published in a paper by Igaku-Shoin, showing that the oxidation-reduction boundary range value for human saliva is 40-50 mV. Similarly, in this invention, the human saliva ORP value index obtained by using plant leaves was utilized to confirm the usefulness of the method of using plant leaves for eyeglass frames. If the ORP value of the human saliva of a subject before and after using the plant leaves is 40 mV or less, which is within the oxidation-reduction boundary range value for human saliva, the subject's body is reduced and in good health. If it is 50 mV or more, it can be determined whether the subject's body is oxidized and in poor health. If the saliva ORP value is within the oxidation-reduction boundary range value, as a follow-up observation, the saliva ORP value of the subject obtained initially is compared with the saliva ORP value of the subject after a predetermined time has elapsed. If the saliva ORP value after the predetermined time has elapsed, it can be determined that the subject is in good health if it has decreased, and in poor health if it has increased. As proof, the usefulness of the eye strain reduction device of the present invention was confirmed through practical verification. Physical condition is measured by the ORP value of the total saliva collected by placing a saliva collection cotton swab on the tongue, as saliva from the parotid gland, submandibular gland, sublingual gland, and minor salivary glands gathers on the tongue inside the mouth.

[0019] Let me explain Figure 6. Figure 6 is an excerpt from the book "Ten no Keiryo," which states that the human saliva ORP threshold value of 40-50mV, based on the human saliva ORP value shown in Figure 5, is limited to a numerical value of 40-50mV for the human health condition ORP threshold value. This is based on local salivary components produced from the submandibular gland in the oral cavity, including albumin, lysozyme, cortisol, IgA, lactoferrin, and gustin. The measurement of human saliva ORP obtained from these components results in a stress level threshold value of plus or minus 0mV to plus or minus 30mV. This stress level measurement was reviewed by the Ministry of Health, Labour and Welfare, and on January 11, 2022, three items—stress level measurement and drug screening level measurement—were officially approved for use in health condition measurement, which had already been approved. This is clearly stated in the medical device documentation for the human saliva ORP measuring device "ORPreader," which is a human medical device certified by the Ministry of Health, Labour and Welfare. When the local salivary ORP value collected from the submandibular gland (a human sample fluid) falls within the stress threshold range of 0-30mV, subsequent measurements during follow-up observation show that if the value decreases from the initially measured value, it indicates a decrease in stress due to the body's reducing state. Conversely, if the value increases, it indicates an increase in stress due to the body's oxidative state. Similar to the physical condition assessment shown in Figure 5, a stress level ORP threshold value of plus or minus 0mV or less indicates no stress. On the other hand, a value of plus 30mV or higher indicates stress.

[0020] Let me explain Figure 7. Figure 7 shows the correlation between human salivary ORP and the autonomic nervous system after viewing plant leaves that have been exposed to light. Using eyeglass frames, the usefulness of viewing plant leaves that have been exposed to light was determined by examining the correlation with the autonomic nervous system 80 to see whether the health effects of the plant's human salivary ORP value act on the sympathetic nervous system 81 or the parasympathetic nervous system 82. Salivary components that act on the sympathetic nervous system 81 include albumin, lysozyme, cortisol, IgA, lactoferrin, and gustin. On the other hand, salivary components that act on the parasympathetic nervous system 82 include amylase, lactoperoxidase, parotin, ptyalin, and histatin. When it acts on the sympathetic nervous system 81, it becomes oxidation 85, resulting in saliva that puts the body in an oxidative, unhealthy state. On the other hand, when it acts on the parasympathetic nervous system 82, it becomes reduction 86, resulting in saliva that puts the body in a reduction, healthy state. Saliva is produced through the blood, as indicated by 87, and saliva is produced through the blood 88. The salivary glands 90 from which saliva is secreted include the parotid gland 91, from which saliva produced in the oral cavity reflects a reducing effect, allowing for the assessment of drug screening levels. Saliva produced in the oral cavity from the submandibular gland 92 reflects an oxidizing effect, allowing for the assessment of stress levels. Saliva produced in the oral cavity from the sublingual gland 93 contains mucin, a salivary component that generates strong reactive oxygen species against viruses entering the oral cavity from the outside, making it an essential salivary component for biological defense, eliminating such invading viruses. Additionally, there are small salivary glands 94 that produce saliva between the teeth and from the gums. It is well known that normally, 2-3% of the reactive oxygen species essential for biological defense are generated. The usefulness of the eye strain reduction device of the present invention was confirmed not only in terms of physical condition but also in terms of stress level measurement, as demonstrated by human salivary ORP measurement.

[0021] Figure 8 is a wavelength diagram of visible light. Figure 46 shows the wavelengths of visible light in the colored light region, with the short wavelengths 47 in the violet, blue, and cyan regions being the visible light region, the medium wavelengths 48 in the green and yellow regions, and the long wavelengths 49 in the red and orange regions. There are concerns about the health effects of wavelengths at both ends of the short and long wavelength ranges in the visible light region of colored light. This is because the short wavelengths in the violet, blue, and cyan regions are close to the ultraviolet (UV) region 54 and the X-ray region 53. On the other hand, the long wavelengths in the red and orange regions are close to the infrared region 55 and the microwave region 56, and it has been published in medical papers that there are concerns about health effects similar to those in the short wavelength region. Sunlight, the light of liquid crystals illuminating the city at night, and light bulbs and lamps are all light that allows the human eye to perceive brightness, and are recognized as light 52 in the visible light region. The ultraviolet (UV) region 54 and the X-ray region 53 are invisible light 50. The infrared region 55 and the microwave region 56, although having different wavelength ranges, are also invisible light 51. The reason for focusing on the fact that the colored light transmitted through the leaves of the plant in this invention, which is visible to humans, is the mid-wavelength 48 in the green and yellow regions of the visible light range, is effective in improving eye strain.

[0022] Let's explain Figure 9. The conditions for the leaves used in this invention are as described in section 69. Specifically, the leaves used are thin-fleshed and green or yellow in color. The use involves the green or yellow light transmitted through the leaves by indirect lighting entering the room or by lighting installed in the room. Even if the leaves are thick-fleshed, any leaves that transmit green or yellow light from indoor lighting can be used in this invention. The leaves should be thin-fleshed, green or yellow in color, and small enough to fit into an eyeglass frame when opened, or the picked leaves should have a fragrant aroma that is expected to have a calming effect. It is also possible to cut freshly picked leaves to a size that fits into an eyeglass frame and use them. If using leaves that have been stored in a refrigerated environment in a freshness-preserving film after being picked, it is desirable to return them to room temperature before use. Since the leaves will come into contact with the skin, after harvesting, they must be washed with distilled water or drinking water and then wiped dry before use. Furthermore, the conditions for leaves that will not be used are explained in section 70, and specifically, leaves from plants grown with chemical fertilizers or pesticides will not be used. Next, leaves containing components toxic to the human body will not be used. Freshness is important, so leaves from fallen plants will not be used. This is because fallen leaves lose their ability to transpire, become dehydrated, and lose their vitality. Since the leaves will come into contact with the skin, it is a condition that leaves whose sap can cause skin irritation will not be used. We will now describe eyeglass frames 71 that can accommodate leaves, which allow the green or yellow light from the plant leaves to pass into the eyeball without having to hold the leaves to the eye with tape or your hands. By using eyeglass frames that contain leaves, the green or yellow light from the leaves that passes into the eyeball is transmitted to the brain by the optic nerve of the eyeball, which receives information from the retina. Therefore, the method of attaching fresh leaves to a person's face in eyeglass frames involves housing the fresh leaves, and the area surrounding the eyeball is cut out in a rounded rectangular shape where a normal eyeglass lens would be, allowing the fresh leaves to come into direct contact with the skin. The aim is to improve eye strain by activating the senses of sight, smell, and touch through the green color, fragrance, and healing components contained within the leaves.Next, we will explain how to check the degree of physical condition resulting from eye strain before and after using the color light of plant leaves using a human saliva ORP measuring device.72 The human saliva ORP measuring device will be used to confirm the usefulness of using plant leaves to improve eye strain.It is known that if the ORP value of the human saliva of the subject before and after using the leaves is 40mV or less, which is the oxidation-reduction boundary range value of human saliva, the subject's body is reduced and in good physical condition.If it is 50mV or more, it can be determined whether the subject's body is oxidized and in poor physical condition. [Examples]

[0023] Table 1 shows that the greenish-yellow light from fresh leaves of the Japanese laurel tree, which had been stored at a low temperature under indoor lighting, was transmitted through eyeglass frames. The experiment was conducted before and after the light transmitted through the plant leaves entered the eye. As a result, the ORP value of human saliva showed a clear indication of reducing activity.

[0024] [Table 1]

[0025] Table 2 shows that the greenish-yellow light from fresh lemon balm leaves, which had been stored in a cool place under indoor lighting, was transmitted through eyeglass frames. The experiment was conducted before and after the light transmitted through the plant leaves entered the eye. As a result, the ORP value of human saliva showed a clear indication of reducing activity.

[0026] [Table 2]

[0027] Table 3 shows that the greenish-yellow light from fresh basil leaves, which were stored in a freshness-preserving film in a refrigerator for two weeks under indoor lighting, was transmitted through eyeglass frames. The experiment was conducted before and after the light transmitted through the plant leaves entered the eye. As a result, similar to Tables 1 and 2, the ORP values ​​of human saliva showed a clear indication of reducing activity.

[0028] [Table 3]

[0029] Table 4 shows that, with the indoor lighting turned off, the yellow-green light from freshly picked shiso leaves (green leaves) was transmitted through a spectacle frame using indirect sunlight entering through a window. The experiment was conducted before and after the light transmitted through the plant leaves entered the eye. As a result, similar to Tables 1, 2, and 3, the human saliva ORP values ​​showed a clear indication of reducing activity.

[0030] [Table 4]

[0031] Table 5 shows that when viewing subjects using eyeglass frames that transmit the yellowish-green light of freshly picked bamboo leaves under direct sunlight, the effects of light transmitted through the plant leaves were verified before and after it entered the eye. As a result, similar to Tables 1-4, the ORP values ​​of human saliva showed a clear reduction effect. In both cases, comparing the use of sunlight and light emitted from indoor lighting, the physical condition and stress levels of subjects improved after using the eyeglass frames of the present invention, which utilize light transmission through plant leaves. In both cases, the ORP values ​​showed a reduction effect, demonstrating the usefulness of transmitting light through plant leaves.

[0032] [Table 5]

[0033] Table 6 shows that the time-dependent changes in human saliva ORP after observing traffic congestion in front of a forest park in the city, without using the aforementioned eyeglass frames that allow the greenish-yellow light of plants to pass through to the eye, and after observing green or yellow leaves in the forest park that were not illuminated by sunlight but were illuminated by sunlight reflecting off them, showed a slight reducing effect. However, unlike the experimental verifications in Tables 1 to 5, which involved observing leaves through which light had been transmitted, strong reduction was not indicated by the human saliva ORP values.

[0034] [Table 6]

[0035] Table 7 shows the results of the experiment, conducted under indoor lighting conditions using both fallen basil leaves and freshly picked basil leaves. Using eyeglass frames that transmit colored light, the experiment was conducted before and after light transmitted through the plant leaves entered the eye. As a result, in the comparison with freshly picked basil leaves, the ORP value of human saliva oxidized after light transmitted through the fallen basil leaves entered the eye. Considering the reason for this, it is known from specialized books that plant leaves lose their life and fall due to the depletion of water through transpiration, which leads to the loss of photosynthesis. Therefore, it is hypothesized that the ORP value of human saliva showed a strong reduction after light transmitted through freshly picked leaves, which still contain dissolved water, entered the eye.

[0036] [Table 7]

[0037] Table 8 shows the temporal changes in human salivary ORP before and after light transmitted through plant leaves was incident on the glabella, located in the center between the eyebrows, using eyeglass frames that transmit the greenish-yellow light of plants, and indoor lighting. The results showed a stronger reducing effect compared to Tables 1-5. Therefore, the significance of incidenting light transmitted through plant leaves to the center of the glabella using eyeglass frames that transmit the greenish-yellow light of plants was confirmed. Considering the results shown in Tables 1-7, the investigation of leaves transmitted by direct sunlight, leaves transmitted by indoor lighting, and green leaves reflected from sunlight revealed that, in comparison with the use of direct sunlight, indirect sunlight entering the room, and indoor lighting, human salivary ORP, depending on physical condition and stress level, can be similarly reduced by using plant leaves and incident light transmitted through plant leaves to the eyes or glabella. Therefore, the eye strain reduction device of the present invention can be used 24 hours a day, regardless of the weather, by utilizing the light from indoor lighting.

[0038] [Table 8]

[0039] Table 9 shows the results of a comparative experiment using artificially created yellow and green lenses within the visible light spectrum under indoor lighting. We hypothesized that if human saliva ORP exhibits a reducing effect when light transmitted through plant leaves is incident on the eye, then human saliva ORP would similarly exhibit a reducing effect when light transmitted through artificially created yellow and green lenses within the visible light spectrum is incident on the eye. Therefore, we conducted a comparative experiment. As a result, after light transmitted through artificially created yellow and green lenses within the visible light spectrum was incident on the eye, the human saliva ORP value oxidized. This confirmed that simply incidentting yellow and green light of the mid-wavelength range within the visible light spectrum on the eye does not cause a reducing effect on human saliva ORP.

[0040] [Table 9]

[0041] Here, we will explain transdermal absorption, which focuses on the absorption of nutrients from leaves that come into direct contact with the skin. Transdermal absorption is believed to occur through the epidermis, the outer layer of the skin. The epidermis is covered with a layer called the stratum corneum, and substances move into the body by passing through this layer. Since substances are absorbed into the body through the skin, drugs and chemical substances can be absorbed through the skin, so it is desirable that the plant leaves used in this invention be grown in a chemical-free and pesticide-free environment. This is because it is well known that chemicals and drugs, especially those with relatively small molecular weights, tend to easily pass through the skin barrier and are easily absorbed transdermally.

[0042] This section explains the glabella (Yintang), located in the center between the eyebrows. This area is considered the eye for perceiving and sensing mysterious things that cannot be perceived by sight, and in yoga, it is called the "third eye" or "eye of the mind." The pineal gland, a part of the brain, is located in the glabella area. The pineal gland secretes the hormone melatonin, which is known to work to correct dangers and imbalances in the body and to sense changes in the surroundings. In yoga, the Yintang is positioned as a chakra and is considered important as it governs not only vital energy but also intuition, insight, and spirituality. For this reason, the parts of the human body that should be touched with the leaves of a target plant that transmits colored light using eyeglass frames are the eyes and the glabella (Yintang) area of ​​the face.

[0043] Photosynthesis is the process by which plant leaves use sunlight to produce nutrients such as starch. This process is called photosynthesis, and it encompasses all metabolic processes, including the breakdown of water by light to produce oxygen, the fixation of carbon dioxide into organic matter, and the extraction of reducing power from the environment using light energy, which is then used to carry out metabolic processes. In photosynthetic organisms, almost all reactions within the cell, whether nitrogen metabolism or sulfur metabolism, should be considered photosynthesis. It is defined and publicly known that when photosynthetic organisms choose to live by using light energy, almost all reactions within their cells are classified as photosynthesis.

[0044] (1) In the eye strain relief device of the present invention, the objective is not to create an intravenous solution containing various vitamins to improve eye strain, nor to improve dietary habits, but rather to utilize the vitality of plants. Focusing on the fact that plants take root in a place even in harsh environments, sprout every year, and possess immeasurable vitality, the aim is to provide the use of the leaves of plants that grow abundantly throughout Japan. However, until now, there has been no visualization of the effect of improving eye strain, and eye strain checks have included items to check for eye symptoms such as heavy eyes, tired eyes, eye fatigue, eye pain, blurred vision, bloodshot eyes, and dry eyes. Furthermore, the confirmation of symptoms other than those related to the eyes, such as stiff shoulders, headaches, fatigue, nausea, decreased concentration, and gastrointestinal problems, has been left to subjective estimation or feeling. Therefore, in order to visualize the effect of improving eye strain using scientifically objective numerical data by focusing on saliva ORP as the theme of non-invasive sample solutions, the present invention conducted measurements using the "ORPreader" human saliva ORP measuring device, which is a human medical device certified by the Ministry of Health, Labour and Welfare.

[0045] (2) In the conventional way, to check the mental state (stress load), stress checks were left to specialists through interviews, and the general public was unable to visualize in real time the scientific and objective health significance of the eyeglass frames and usage method using the plant leaves of the present invention on human health.

[0046] The present invention's eye strain reduction device utilizes thin, green, or yellow light transmitted through the eyeball, stimulating the eye with the mid-wavelength visible light frequencies of the green leaves. Simultaneously, it allows for transdermal absorption of nutrients from the plant leaves through the skin covering the eyeball. Furthermore, the use of thin leaves that transmit green light is considered desirable because sunlight penetrates through the leaf, reaching the underside of the leaf and increasing photosynthesis throughout the entire leaf. Transdermal absorption of audible light in the healing range and nutrients from the leaves is achieved, and it is also considered that transdermal absorption of a small amount of oxygen can be expected through photosynthesis using indirect light, even without direct sunlight. Therefore, the use of plant leaves is not limited to leaves immediately after picking. Table 3 shows that even with basil leaves, which were collected fresh, stored in a freshness-preserving film, and refrigerated for two weeks, the reduction of human salivary ORP after holding the basil leaves to the eye using the eyeglass frame of the present invention was clearly demonstrated. Table 7 clearly suggests a difference in the oxidation-reduction potential of human salivary ORP between fallen leaves and fresh leaves.

[0047] Here, we will describe the principle and effect of the saliva ORP measuring device used to verify the effects of the present invention. The principle of oxidation-reduction potential is that ORP (Oxidation Reduction Potential) is a numerical value that expresses the difference between the oxidizing power and the reducing power as a potential difference. Oxidation is a chemical reaction in which electrons are lost, specifically a reaction in which oxygen is added to a substance, or a reaction in which hydrogen is removed from a substance. Reduction is a chemical reaction in which electrons are added, specifically a reaction in which oxygen is removed from a substance, or a reaction in which hydrogen is added to a substance. By measuring the activity ratio of oxidized and reduced forms of saliva, which is a biological substance in the human body, and by setting up at least a reference electrode and a working electrode, the oxidation-reduction reaction is measured using saliva, which is a sample solution in contact with the working electrode, and the potential difference of the level of oxidizing power and reducing power, indicating whether the oxidizing power or the reducing power is stronger, is expressed. We focused on utilizing this principle in a saliva ORP measuring device in an eye strain reduction device.

[0048] The applicant for this invention has already filed the following patents to confirm the effects on human health (for example, Patent No. 6142122, Patent No. 6251878, Patent No. 6253171, Patent No. 6454836, Patent No. 7065236, Patent No. 7065247, Patent No. 7282990, and Patent No. 7336166).

[0049] As shown in Figure 5, the oxidation-reduction boundary range value for human saliva, as quantified by the human saliva ORP index in a paper published by Igaku-Shoin, is indicated as 40-50 mV. Thus, the usefulness of the eyeglass frame and method of use utilizing plant leaves of the present invention can be confirmed by comparing the ORP value of the subject's saliva before and after use of raw leaves. If the ORP value of the subject's saliva is 40 mV or less, it indicates that the subject's body is reduced and in good health. If it is 50 mV or more, it can be determined that the subject's body is oxidized and in poor health. If the saliva ORP value falls within the oxidation-reduction boundary range, the subject's saliva ORP value obtained initially is compared with the subject's saliva ORP value after a predetermined time has elapsed. If the saliva ORP value after the predetermined time has elapsed, it can be determined that the subject is in good health if it has decreased, and in poor health if it has increased. Thus, the usefulness of improving eye strain has been visualized.

[0050] In the eye strain reduction device of the present invention, the light is not necessarily limited to sunlight. Regardless of the weather, it is possible to use the light from indoor lighting, and 24 hours a day, not only during the day but also at night, to transmit the green-yellow light of plants to the human eye using eyeglass frames that can hold leaves that have been stored in a household refrigerator. Conventionally, it has been believed that looking at green plants provides a sense of peace. The substance that receives light in plant leaves is mainly chlorophyll, which, when exposed to light, distinguishes the color of the light, absorbs blue and red light, and reflects or allows green light to pass through. However, this eye strain reduction device utilizes the property of plant leaves to allow green light to pass through, rather than reflecting it, and causes the light transmitted through the plant leaves to enter the eye.

[0051] Plants whose leaves allow light to enter the eye include: Japanese spindle tree leaves, lemon balm leaves, basil leaves, mint leaves, Japanese mint leaves, sesame leaves, perilla leaves, angelica tree leaves, molokhia leaves, mitsuba, watercress leaves, mustard greens leaves, kale leaves, moringa leaves, Eucommia tea leaves, bamboo leaves, ginger leaves, banana leaves, lemon leaves, coffee tree leaves, bay laurel leaves, maple leaves, apple leaves, mandarin orange leaves, kumquat leaves, salad tree leaves, oak leaves, persimmon leaves, akebia leaves, and sunflower leaves. These include tea leaves, zelkova leaves, beech leaves, lettuce leaves, green perilla leaves, banyan leaves, akebia leaves, Oshima cherry leaves, Somei Yoshino cherry leaves, Japanese evergreen oak leaves, horse chestnut leaves, poplar leaves, silk tree leaves, sakaki leaves, nandina leaves, hibiscus leaves, mugwort leaves, cabbage leaves, komatsuna leaves, sweet potato leaves, ginger leaves, rapeseed leaves, sashigusa leaves, dandelion leaves, mulberry leaves, sweet potato leaves, bamboo leaves, green bean leaves, blueberry leaves, or plane tree leaves. For other plant leaves, those with a high effect in reducing eye strain were selected based on human saliva ORP measurement. The leaves used to expose the eyes to light are not those that are known to cause skin irritation or toxicity upon contact with human skin, or that pose a risk to human health, as documented in botanical guides and herbal medicine textbooks. The plant leaves used in this invention have been confirmed to improve physical ailments believed to be caused by eye strain in subjects using a human saliva ORP (oxidation-reduction potential) measuring device. Since the leaves used in this invention are fresh leaves, harvesting them from one's garden is ideal. However, if it is not possible to grow the plants, fresh, domestically produced leaves can be obtained from online shops and stored in the refrigerator.

[0052] This section explains why plant leaves were used in the eye strain reduction device of the present invention. Focusing on the difference in reduction values ​​shown in Table 9 of the comparative implementation verification of a human saliva ORP oxidation-reduction potential measuring device, which measures light transmitted through plant leaves and incident on the eye, the applicant arrived at the following considerations. When plant leaves are exposed to sunlight, the chloroplasts within the leaves use the energy of the light to produce oxygen and starch from carbon dioxide and water, and grow through photosynthesis, bloom flowers, get pollinated, produce fruit, and store starch. The underside of plant leaves has tiny holes called stomata that allow gases to enter and exit. It is well known that transpiration is the process by which water inside the plant body with these stomata turns into water vapor and leaves the leaves. Based on the plant mechanisms hidden within the picked leaves, we focused on the idea that by using a holder that keeps the plant leaf in front of the human eye and directing the light transmitted through the leaf into the eye or between the eyebrows, the fragrance of the plant leaf emitted from the plant mechanism, as well as the fine water vapor produced by photosynthesis in the chloroplasts, can be transmitted to the human eye or between the eyebrows. It is expected that this will enhance the eye strain reduction effect of the present invention, as information about the plant mechanism will be transmitted, and a small amount of oxygen will be supplied to the fine optic nerve of the eyeball through transdermal absorption. Therefore, we were able to confirm the usefulness of reducing eye strain using a human saliva ORP oxidation-reduction potential measuring device, and furthermore, we were able to visualize and confirm the selection of leaves with a high eye strain reduction effect.

[0053] The eyeglass frames used in the eye strain reduction device of the present invention should preferably be made of a flexible material to prevent damage when the user falls asleep, closes their eyes, or turns over in their sleep, while using the device while sitting in a chair or lying on their back on a sofa, allowing light transmitted through plant leaves to enter the eyes or between the eyebrows. For example, a soft type molded from polyethylene terephthalate, the same soft material used in night guards that protect teeth and jaws from grinding and clenching, or molded from natural rubber, the same material used in baby pacifiers, would be preferable. This is because, when using the eyeglass frames, it is impossible to keep the eyes open without blinking at all while light transmitted through plant leaves enters them. When using the eyeglass frames, we wanted to enhance the usefulness of the eye strain reduction device of the present invention by allowing the user to relax and use the device in a way that places less strain on the body.

[0054] The origin of the idea for the eye strain reduction device of this invention lies in the applicant's childhood memories of spending time in the scorching summer sun. There were towering trees in parks and schoolyards, and he walked long mountain paths, crossing many mountains to collect cedar leaves and gather wild vegetables, but the leaves of the forest provided shade from the blazing sun. He considered why, even after playing under these trees until it got dark, he didn't feel tired and was able to spend the next day feeling energetic. There are camphor trees with lush leaves all year round, zelkova trees whose leaves change color from fresh green to autumn, ginkgo trees whose leaves shine golden from fresh green to autumn, maple trees whose leaves change color from fresh green to autumn, plane trees, cedar trees, oak trees, and beech trees, and I focused on the idea that being exposed to the leaves of plants that have transmitted direct sunlight through them means that a medium-wavelength greenish-yellow light in the visible light range pours down, and that spending time under this dappled sunlight may have kept the body healthy thanks to the benefits of the vitality of plants. I also paid close attention to the relationship between sunlight and plants, as the leaves of fruit trees sprout green at first, then turn from light green to deep green, and then golden in autumn, and the fruits also change color from green to yellow, orange, and red as they grow. [Industrial applicability]

[0055] With the rapid proliferation of LCD screens in workplaces, schools, homes, and cities, such as those on personal computers and smartphones, the number of people complaining of eye strain is increasing. Since eye strain can trigger health problems such as dry eye, cataracts, glaucoma, age-related macular degeneration, and diabetes, the eye strain reduction device of this invention can be used 24 hours a day, regardless of weather conditions, by utilizing indoor lighting rather than sunlight. We believe that the use of plant leaves, which are naturally produced year after year throughout the four seasons, is an environmentally conscious and abundant renewable resource that greatly contributes to the healthy lifespan of humans.
