Description

Technical Field

[0001] The utility model relates to an eye mask, belonging to the technical field of health and medical equipment products. Background Art

[0002] Hard corneal lenses or flexible corneal lenses are commonly used non-surgical myopia intervention products. They keep in close contact and compress the cornea for several hours a day to prevent the curvature of the central pupil area of ​​the cornea from being too large, thereby delaying the development of myopia. However, they also produce a variety of side effects such as dry eyes, corneal foreign body sensation, corneal ulcers, and mechanical corneal damage. The corneal microecological environment is also significantly damaged, causing continuous pain to users. The cornea is the window for external light to enter the eyeball, and it is also the pathway for external harmful physical and chemical factors to damage the eyeball. For example, dry air, various harmful particles in the air, pathogenic microorganisms, and harmful gases can directly damage the cornea and the sclera, conjunctiva, lacrimal glands, meibomian glands and other physiological structures around the cornea. The existing technology still lacks a non-surgical system solution that comprehensively considers the adjustment of refractive errors, tear film stabilization, protection against external eye infections, and anti-oxidant damage. Summary of the invention

[0003] The utility model provides an eye mask, which can construct a warm or cool, moist, clean, and air-negative ion-rich extraocular microenvironment and can assist the user in adjusting to a emmetropia state. The pressure in the inner cavity of the eye mask can safely act on the cornea to delay or reverse the increase in corneal curvature.

[0004] The purpose of the utility model is achieved as follows: an eye mask, which covers the outside of a single eyeball of a person, wherein the internal space of the eye mask forms an eye mask inner cavity, wherein the eye mask inner cavity is provided with an eye mask inner opening which can at least accommodate the cornea; when in use, the eye mask inner opening faces the eye socket and can be closed by the skin at the eye socket, wherein the fluid in the eye mask inner cavity directly or indirectly acts on the central pupil area of ​​the cornea, wherein the eye mask is connected with a hollow primary extension part, wherein the internal space of the primary extension part forms a fluid channel, wherein the fluid channel is connected with the eye mask inner cavity, wherein a terminal window which can be penetrated by the visual axis is provided at the far end of the fluid channel; wherein a fluid communication port is further provided on the fluid channel and / or the eye mask inner cavity, wherein the external fluid can enter the eye mask inner cavity through the fluid communication port and / or the terminal window so as to directly or indirectly act on the eyeball.

[0005] The terminal window through which the visual axis can pass is provided at the far end of the fluid channel, which means that external light can coincide with the visual axis through the terminal window, projecting the optical fiber to the macula of the retina.

[0006] The eye mask is in a cup, bell, bowl or other shape, and one eye mask is only for one eyeball; the fluid channel and the eye mask can be made of one component in one piece, or can be formed by connecting two or more components.

[0007] The external fluid indirectly acts on the eyeball, which means that the external gas or liquid does not directly contact the eyeball but indirectly contacts the eyeball, especially the cornea, through a medium; the terminal window cover can cover the terminal window, and the terminal window cover can be made of opaque material or translucent material such as a material with a small light transmittance coefficient; when in use, the direction toward the eyeball is inward, the one close to the eyeball is the proximal end, and the one far away from the eyeball is the distal end.

[0008] The terminal window is in an open state or a non-open state to allow fluid to pass through. The open state means that there is no obstruction at the terminal window, and gas can enter the fluid channel through the outside of the terminal window. In one case, the terminal window can be covered by a light-transmitting window when it is in a non-open state. The terminal window is composed of a light-transmitting window, which means that the material used to make the window is light-transmitting or the window is conductive and light-transmitting. In another case, the non-open state of the terminal window means that the terminal window is closed by a window cover, and the window cover, which is integrally arranged or independently detachable, does not allow external light to enter the fluid channel, but a light-emitting component or a beneficial light releasing module can be arranged on the inside of the window cover. The light generated by the light-emitting component or the beneficial light releasing module can enter the user's eyeball through the fluid channel and then through the cornea, that is, guide the user's eyeball position so that the central pupil area faces the terminal window at the far end of the fluid channel, especially the center position of the terminal window, at which time the light coincides with the visual axis.

[0009] Furthermore, it also includes one or more of a first adjustment module for adjusting the degree of opening of the terminal window, a second adjustment module for adjusting the forward and backward movement of the terminal window and / or the eye mask position, a third adjustment module for adjusting the upward and downward movement of the terminal window position, and a fourth adjustment module for adjusting the left and right movement of the terminal window position.

[0010] The first adjustment module is directly connected to the primary extension part or the secondary extension part of the eye mask where the terminal window is located, or is indirectly connected to the terminal window through other components; whether the terminal window is open includes: 1. whether light is allowed to enter; 2. whether the terminal window is blocked by the window cover; it also includes adjusting the opening degree of the terminal window, specifically including: 1. different areas of the terminal window that allow light to pass through; 2. the degree to which the terminal window allows light to pass through, that is, the transmittance.

[0011] The moving direction of the terminal window is specifically set as follows: when the eye mask is used, the direction close to the forehead is up, the direction close to the mouth is down, the direction close to the right arm is right, and the direction close to the left arm is left; the terminal window can be located on the primary extension part, on the secondary extension part, or on other auxiliary components.

[0012] In order to provide abundant negative air ions such as negative air hydrogen ions and negative air oxygen ions, the invention also includes a negative ion release terminal arranged in the inner cavity of the eye mask and / or the fluid channel, and the negative ion release terminal is driven by the negative ion module; at least the end portion of the carbon fiber brush or the metal tip component is the negative ion release terminal, and the negative ion release terminal is in contact with the gas in the inner cavity of the eye mask and / or the fluid channel.

[0013] The optimized structure is that the eye mask is connected with a hollow primary extension part and / or a secondary extension part, and the eye mask and the primary extension part or the secondary extension part are connected flexibly so that their relative positions can be restored to the initial position after relative movement occurs; the relative position of the eye mask and the primary extension part or the secondary extension part can be restored after the movement means that the two are in a coaxial position relationship. Because the eye mask and the eyeball may be in direct contact, the external force generated by the eyeball movement acts on the eye mask so that the central axis of the eye mask and the central axis of the fluid channel change at a certain angle. When the eyeball movement ends, the external force disappears, and the flexible connection with restoration ability restores the two to the state before the external force acts, that is, the coaxial position relationship; the degree of the flexible connection can at least resist gravity, and the coaxial position relationship between the two is not changed due to gravity, but it does not significantly hinder the eyeball movement, especially the eyeball rotation during rapid eye movement sleep, so as to avoid discomfort to the user caused by excessive resistance.

[0014] For comfortable contact and better sealing, at least the part of the eye mask that contacts the eye socket skin is made of a flexible material; the flexible material may be a thermoplastic elastomer, silicone rubber, a soft hydrogel, a soft hydrogel combined with a support, and the like.

[0015] In order to provide a better extraocular microenvironment, a gas control module is also included, and the gas regulated by the gas control module enters the inner cavity of the eye mask through the fluid connecting port on the fluid channel; the gas control module includes functions that refer to one or more of the following: 1. Gas purification; 2. Gas humidification, including atomization of aqueous solution; 3. Gas temperature control, constant temperature, temperature increase or temperature decrease; 4. Harmful gas treatment; 5. Release of beneficial gases such as hydrogen, gaseous drugs, etc.; 6. Air flow speed control, such as constant rate, pulsating rate, etc.; 7. Gas pressure control.

[0016] Furthermore, it also includes a beneficial light releasing module, and the beneficial light generated by the beneficial light releasing module enters at least the central pupil area of ​​the cornea through the fluid channel; the beneficial light releasing module may refer to a full-spectrum or other light releasing module that is beneficial to vision protection or health.

[0017] In order to keep the microenvironment outside the eyeball moist, a hydrogel component is also included, at least a portion of which is exposed in the inner cavity of the eye mask, and the exposure method is one or more of flat exposure, villi-like exposure, pleated exposure, and filled exposure; the eye mask is provided with a hydrogel containing space and / or a liquid water storage space.

[0018] The hydrogel containing space can be a hydrogel containing space formed by a containing groove, and the hydrogel component can also be fixed by a fixing arm, a fixing clamp, etc. The hydrogel containing space can be a part of the inner cavity of the eye mask, and the inner cavity of the eye mask directly contains the hydrogel component. The hydrogel containing space can also protrude from the inner cavity of the eye mask without occupying the inner cavity of the eye mask; the filled hydrogel component can be directly embedded in the inner cavity of the eye mask; the hydrogel component can contain volatile Chinese and Western medicines, and the storage space for precipitated water or condensed water of the hydrogel component can be groove-shaped or capsule-shaped.

[0019] A more optimized structure, wherein a membrane-like isolator is provided at the opening inside the eye mask, the central area of ​​which is easily deformed after being subjected to force, a transparent belt is provided in the central area of ​​the isolator, the isolator divides the inner cavity of the eye mask into a first inner cavity of the eye mask and a second inner cavity of the eye mask, the isolator prevents the fluid in the second inner cavity of the eye mask from entering the first inner cavity of the eye mask, and the opening inside the eye mask is connected to the fluid in the first inner cavity of the eye mask.

[0020] The isolator is preferably made of a transparent material, and a transparent band is provided in the central area of ​​the isolator, which means that at least the entire central area or the central point is partially transparent. The central area refers to the area facing the central pupil area of ​​the cornea when in use, and the central point of the central area faces the central point of the central pupil area of ​​the cornea. The isolator and the eye mask are preferably detachably combined, and the sterile isolator is preferably used as a consumable material.

[0021] In order to increase the contact area between the eye mask and the skin at the eye socket, the edge of the opening inside the eye mask is folded, and the folded space area is not connected to the external environment or is connected to the external environment through pores.

[0022] The edge of the opening in the eye mask is folded inward or outward, and can be folded in one layer or in multiple layers. The folded structure can increase the contact area with the eye socket skin and better reduce the pressure during contact. When gas is continuously injected into the inner cavity of the eye mask, the folded space area can instantly buffer the gas pressure, and the gap on it can fully release the pressure to avoid the high gas pressure in the inner cavity of the eye mask causing discomfort to the eyeball. The folded structure that is not connected to the outside can keep the gas pressure in the inner cavity of the eye mask stable or increase the pressure continuously.

[0023] In order to better fix the eye mask, an eye mask bracket is also included. The eye mask bracket is in direct or indirect contact with the eye mask to support, accommodate and fix all or part of the eye mask, the first adjustment module, the second adjustment module, the third adjustment module, the fourth adjustment module and the gas control module.

[0024] The beneficial effects of the utility model are:

[0087] The embodiments of the present invention are not limited to the following:

[0088] Embodiment 1:

[0089] like Figure 1A , Figure 1B , Figure 1C As shown, an eye mask 1 can be in a cup shape, a bell shape, a bowl shape, etc., and covers the outside of a single eyeball E of a person, the opening 101 in the eye mask faces the eye socket O, the edge portion 12 of the opening 101 in the eye mask fits the skin at the eye socket O, the upper eyelid D1 and the lower eyelid D2 are partially located in the eye mask cavity 10, and the cornea C is located in the eye mask cavity 10. Figure 1A , the area between the upper edge horizontal line S1 and the lower edge horizontal line S2 of the iris I is the central pupil area C0 of the cornea; Figure 1BThe sclera S next to the cornea C is shown, the eye mask 1 is connected to a hollow primary extension part 11, the internal space of the primary extension part 11 forms a fluid channel 110 that is connected to the eye mask inner cavity 10, and a fluid communication port 111 is also provided on the fluid channel 110. A terminal window 112 that can be penetrated by the visual axis A is provided at the distal end of the fluid channel 110, and the terminal window 112 can be closed by a window cover 115; when in use, the eye mask 1 or the primary extension part 11 is held by hand, and when the window cover 115 is removed, the eyeball E looks at the terminal window 112, and looks at the blue sky or distant objects through the terminal window 112, and the central axis of the fluid channel 110 and the eye mask inner cavity 10 coincides with the visual axis A, that is, External light enters the eye from the terminal window 112 along the visual axis A through the central pupil area C0 of the cornea and the lens L with the iris I connected to the periphery, and stimulates the fovea area M of the retina. The generated visual signal is transmitted to the visual center through the optic nerve tube N. In this case, not only the refractive system of the eyeball E is relaxed, but also the external fluid, especially warm or cool, moist, clean air rich in negative oxygen ions or negative hydrogen ions, can enter the fluid channel 110 and the eye mask inner cavity 10 through the fluid connecting port 111. The generated gas pressure acts on the central pupil area C0 of the cornea, causing the central pupil area C0 of the cornea to deform toward the lens L on a micro scale, thereby alleviating the central pupil area C0 of the cornea. For myopia caused by convex cornea C0, precise air compression multiple times a day for a certain period of time each time can play a similar role as hard corneal lenses in counteracting the convex cornea C; for people who have used hard corneal lenses to relieve myopia, it can help consolidate the treatment effect; and for problems such as dry eyes, eye fatigue, pain, and corneal surface flora imbalance caused by hard corneal lenses, the eyeball E extracellular microenvironment formed by the eye mask inner cavity 10 with warm or cool, moist, clean air rich in negative oxygen ions or negative hydrogen ions can eliminate or alleviate the above-mentioned dry eyes and other problems to the greatest extent, especially the direct compression of the cornea by the hard corneal lens causes corneal epithelial cell dysfunction, and the tiny particles in the external air can also cause dry eyes. Oxidants on particles and fine particles are more likely to adhere to the surface of the cornea C, further damaging the cornea C, while a clean or even pure extra-ocular microenvironment without particles can fully protect the cornea C, a moist extra-ocular microenvironment helps stabilize the tear film, a warm or cool extra-ocular microenvironment helps improve the blood supply around the cornea C and promote corneal C metabolism, and abundant negative oxygen ions or negative hydrogen ions with reducing ability can significantly reduce oxidative damage to corneal epithelial cells; for people who use hard corneal lenses or flexible corneal lenses, using the present invention to maintain the cornea after removing the corneal lenses can reduce or eliminate the side effects of the corneal lenses and consolidate the effect of intervention on corneal curvature.

[0090] One eye mask 1 is only for one eyeball E; the fluid channel 110 and the eye mask 1 can be made of an integral component, or can be formed by connecting two or more components; the terminal window cover 115 can cover the terminal window 112, and can be made of opaque material and / or material with low light transmittance; after the terminal window 112 is covered, the microenvironment outside the eyeball E can still function fully, especially when the eyes are open; when the eyes are closed, negative oxygen ions or negative hydrogen ions can still enter from the palpebral fissure between the upper eyelid D1 and the lower eyelid D2 to protect the cornea C.

[0091] The primary extension 11 of the eye mask 1 of this embodiment is provided with an extension side branch 113, and external air enters the side branch inner cavity 1130 through the extension side branch outer opening 114, then enters the fluid channel 110 through the fluid communication port 111, and then enters the eye mask inner cavity 10; for comfortable contact and better sealing, the eye mask 1 is preferably made of a flexible material, and when in use, at least the edge portion 12 of the eye mask inner opening 101 of the eye mask will contact the skin at the eye socket O, and at least this edge portion 12 should be made of a flexible material such as silicone rubber, thermoplastic elastomer, etc.

[0092] Embodiment 2:

[0093] like Figure 2A , Figure 2B , Figure 2C As shown, in order to adjust the distance between the terminal window 112 and the eyeball E, the primary extension portion 11 of the eye mask 1 is provided with a tubular secondary extension portion 13 that can slide with the primary extension portion, the distal surface 116 of the primary extension portion faces the terminal window 112, the distal opening 1160 of the primary extension portion is connected to the secondary extension portion inner cavity 130, the terminal window 112 is opened on the distal surface 131 of the secondary extension portion, and the terminal window cover 115 can cover and seal it.

[0094] An extension side branch 113 is provided on the primary extension part 11, and the side branch can also be provided on the secondary extension part 13; external air enters the side branch inner cavity 1130 through the extension side branch outer opening 114, then enters the fluid channel 110 through the fluid connecting port 111, and then enters the eye mask inner cavity 10, forming a good microenvironment outside the eyeball E. In order to maintain air circulation, a vent 103 is provided near the edge portion 12 of the eye mask inner opening 101. The airflow in the microenvironment outside the eyeball E flows out of the eye mask inner cavity 10 through the vent 103, and while renewing the air, it also takes away waste gases such as carbon dioxide generated by the physiological metabolism of the cornea C, sclera S, upper eyelid D1, and conjunctiva of the lower eyelid D2.

[0095] Embodiment 3:

[0096] like Figure 3A , Figure 3B , Figure 3CAs shown, the biggest difference from Example 2 is that the distal end of the primary extension part 11 is closed by a primary window 112a which is transparent at least in the central area, and the primary window 112a is connected to the distal end surface 116 of the primary extension part as a whole. The primary window 112a isolates the secondary extension part cavity 130 from the fluid channel 110 without blocking the light from the terminal window 112; without affecting the adjustment of the distance between the terminal window 112 and the eyeball E, the external air entering the fluid channel 110 directly enters the eye mask cavity 10 to form a microenvironment outside the eyeball E, thereby avoiding air from entering the dead space, that is, entering the secondary extension cavity 130.

[0097] Another difference is that the primary extension portion 11 is provided with a tubular inner protrusion section 117 protruding toward the eyeball E, and an annular hydrogel component G for humidifying the air in the eye mask inner cavity 10 is embedded in the annular space between the inner protrusion section 117 and the eye mask 1. At least a portion of the hydrogel component G is exposed in the eye mask inner cavity 10. In order to increase the humidification surface area, the hydrogel component G needs to be exposed as much as possible. In this example, a plurality of annular protrusions G1 are provided on the hydrogel component G; the surface exposure of the hydrogel component G can be one or more of large-area flat exposure, villi protrusion exposure, pleated exposure, and filled exposure; the hydrogel component G can be molded from chemical raw materials such as polyvinyl alcohol and sodium polyacrylate, but is preferably made of natural polymer materials such as konjac gum, alginate gel, carrageenan, etc., and a variety of traditional Chinese medicine eye protection ingredients such as dendrobium, musk, houttuynia cordata, pearls, etc. can be added therein. The hydrogel component G preferably has a water content greater than 90% to facilitate humidification of the air in the microenvironment outside the eyeball E.

[0098] Embodiment 4:

[0099] like Figure 4A , Figure 4B , Figure 4C As shown, different from Example 3, the hydrogel component G of this example is located in the annular recess 102 on the eye mask 1, and the corresponding external protrusion 1021 of the annular recess protrudes out of the eye mask 1. Under this design, the hydrogel component G does not occupy or does not significantly occupy the space of the eye mask inner cavity 10, and the hydrogel component G as a consumable material is also easy to be installed in the annular recess 102.

[0100] Embodiment 5:

[0101] like Figure 5A , Figure 5B , Figure 5C As shown, the eye mask 1 is provided with not only a hydrogel component G accommodating space, i.e., an annular recess 102, but also a liquid water storage space 104 for temporarily accommodating the hydrogel component G that may precipitate during use. The arc-shaped liquid water storage space 104 is located at the lower part of the eye mask 1, i.e., a region closer to the lower eyelid D2, and below the edge portion 12 of the opening 101 in the eye mask. Figure 5CThe external protrusion 1041 corresponding to the liquid water storage space 104 is shown in three dimensions; the precipitated liquid water refers to the liquid water directly precipitated from the hydrogel component G due to temperature changes. The inner cavity 10 of the eye mask will also form liquid water due to condensation of water vapor during use, which will temporarily flow into this storage space 104 without contacting the skin and causing discomfort.

[0102] The extension side branch 113 of this example is axially arranged at the distal end of the primary extension part 11 adjacent to the terminal window 112. A window tube 119 is arranged at the distal end of the primary extension part 11 facing the opening 101 in the eye mask. The terminal window 112 is located at the distal end of the window tube 119. The axis of the window tube inner cavity 1190 coincides with the axial direction of the fluid channel 110. External air enters the window tube annular gap 1191 through the fluid connecting port 111 and then flows into the eye mask inner cavity 10. Unlike the radially arranged extension side branch 113 described in the previous embodiment, the air flows more smoothly and directly acts on the cornea C.

[0103] Embodiment 6:

[0104] like Fig. 6A , Figure 6B , Figure 6C As shown, the edge portion 12 of the opening 101 in the eye mask is folded, and the folded space area 120 is connected to the outside in one of the following ways: no connection, connection with the through hole 105, and connection with a one-way pore (not shown). Or a combination of these.

[0105] The edge portion 12 of the opening 101 in the eye mask is folded inward (not shown) or outward, and can be folded in one layer or in multiple layers. This example shows that it is folded outward. The soft folding structure can increase the contact area with the skin of the eye socket O and better reduce the pressure during contact. When gas is injected into the eye mask cavity 10 through the extension side branch 113, the folded space area 120 can instantly play a role in buffering the gas pressure, and the through hole 105 thereon can fully release the pressure to avoid the high gas pressure in the eye mask cavity 10 causing discomfort to the eyeball E. The folding structure that is not connected to the outside can keep the gas pressure in the eye mask cavity 10 stable or continue to increase the pressure.

[0106] Considering the rotation of the user's eyeball E when awake or asleep, the rotating eyeball E will cause displacement between the eye mask 1 and the primary extension part 11 or the secondary extension part 13 connected thereto and constituting the fluid channel 110. To solve this problem, the eye mask 1 and the primary extension part 11 or the secondary extension part 13 are connected in a flexible manner so that their relative positions can be restored after movement. In this embodiment, a flexible annular corrugated protrusion 118 that is easy to bend is provided at the junction of the primary extension part 11 and the eye mask 1. When the distal end of the primary extension part 11 is held or fixed by a finger, the bent corrugated protrusion 118 is also easy to restore to its original state after the external force is released. The relative position of the extension part 13 and the extension part 13 can be restored, which means that the two are in a coaxial position relationship. Since the eye mask 1 and the eyeball E may be in direct contact, the external force generated by the movement of the eyeball E acts on the eye mask 1 so that the central axis of the eye mask 1 and the central axis of the fluid channel change at a certain angle. After the movement of the eyeball E ends, it returns to the natural position, and the external force driving the displacement of the eye mask 1 disappears. The flexible connection with the restoring ability restores the two to the state before the external force acts, that is, the coaxial position relationship state; the degree of the flexible connection can at least resist gravity, and the coaxial position relationship between the two is not changed due to gravity, but it does not significantly hinder the movement of the eyeball E, especially the rotation of the eyeball E during rapid eye movement sleep, so as to avoid discomfort to the user caused by excessive resistance.

[0107] The terminal window 112 is covered with a light-transmitting window 112b, which isolates the external air, and at least the central area of ​​the light-transmitting window 112b is light-transmitting; the terminal window 112 of the present invention can be in an open state or a non-open state, and the terminal window 112 can be covered by a light-transmitting window 112b when it is in a non-open state; the open state means that there is no obstruction at the terminal window 112, and the gas can enter the fluid channel 110 through the outside of the terminal window 112; the terminal window 112 is composed of a light-transmitting window 112b, which means that the material used to make the window is light-transmitting or the window is conductive and light-transmitting; the terminal window 112 is in a non-open state, which means that the terminal window 112 is closed, as shown in this embodiment; the light-transmitting window 112b can also play a filtering role to filter out ultraviolet rays that are harmful to the human body.

[0108] Embodiment 7:

[0109] like Fig. 7A , Figure 7B , Figure 7C , Fig.7DAs shown, in order to better humidify the air in the inner cavity 10 of the eye mask, in this example, the hydrogel component G is cup-shaped and located in the inner cavity 10 of the eye mask, and the tubular extension G2 of the hydrogel component penetrates into the primary extension 11. A support body 15 is provided outside the hydrogel component G to ensure the softness of the hydrogel component G. The support body 15 of this example is a plurality of connected ribs, and the rib gaps 150 are blocked by the hydrogel component G, so that the external air will not enter the inner cavity 10 of the eye mask through the rib gaps 150. This design makes the overall weight of the eye mask 1 lighter under the premise of ensuring sufficient humidification capacity. Compared with the previous embodiment, a large area of ​​the hydrogel component G in this embodiment is exposed to the inner cavity 10 of the eye mask, so that the humidity in the microenvironment outside the eyeball E is significantly improved; Fig.7D In order to better maintain the shape of the hydrogel component G, a hydrogel convex strip G3 which can be embedded in the rib gap 150 is provided on the outer surface of the hydrogel component G.

[0110] Embodiment 8:

[0111] like Fig. 8A , Figure 8B , Figure 8C As shown, the hydrogel component G of this example is provided with a free portion G0 of the hydrogel component that penetrates into the inner cavity 10 of the eye mask. The free portion G0 of the hydrogel component divides the inner cavity 10 of the eye mask into a first inner cavity 10a of the eye mask and a second inner cavity 10b of the eye mask. The free portion G0 of the hydrogel component prevents the fluid in the second inner cavity 10b of the eye mask from entering the first inner cavity 10a of the eye mask. In this case, the inner opening 101 of the eye mask is an external opening of the first inner cavity 10a of the eye mask. The inner side of the edge portion 12 of the inner opening 101 of the eye mask is provided with an annular convex rib 121 that protrudes toward the inner cavity 10 of the eye mask. The annular convex rib 121 constrains the peripheral portion of the free portion G0 of the hydrogel component, making it difficult to contact the skin of the upper eyelid D1 and the lower eyelid D2. The hydrogel component G inserted into the inner cavity 10 of the eye mask can not only fully humidify the air but also be integrated with Chinese and Western medicines to exert corresponding pharmacological effects, and can also press the cornea without sterility or irritation.

[0112] At least the central area G00 of the free part of the hydrogel component is transparent. When the eyeball E looks at the blue sky or observes a fixed object in the distance through the terminal window 112, the light entering the eye mask inner cavity 10 at least enters the corneal central pupil area C0 through the transparent central area G00 of the free part. The gas pressure from the second inner cavity 10b of the eye mask can press the central area G00 of the free part of the hydrogel component toward and contact the corneal central pupil area C0. The central area G00 of the free part can transmit pressure to the corneal central pupil area C0 to prevent the corneal central pupil area C0 from protruding outward, thereby playing a myopia relief effect similar to that of a hard corneal lens. When the eyes are closed, the pressure is transmitted to the corneal central pupil area C0 through the upper eyelid D1 and the lower eyelid D2. Because the central area G00 of the free part of the hydrogel component is as soft as water, it can fully conform to the upper eyelid D1 and the lower eyelid D2 to better transmit the pressure.

[0113] Embodiment 9:

[0114] like Fig. 9A , Fig. 9B , Fig. 9C As shown, a flexible membrane-shaped isolator 14 is provided at the opening 101 in the eye mask, and its central area 140 is easily deformed after being subjected to force. A transparent belt is provided in the central area 140 of the isolator 14. The isolator 14 divides the eye mask inner cavity 10 into a first inner cavity 10a and a second inner cavity 10b of the eye mask. The isolator 14 prevents the fluid in the second inner cavity 10b of the eye mask from entering the first inner cavity 10a of the eye mask. In this case, the eye mask inner opening 101 is an external opening of the first inner cavity 10a of the eye mask; an annular groove 122 convex to the eye mask inner cavity 10 is provided on the inner side of the edge portion 12 of the eye mask inner opening 101, and the edge portion 141 of the isolator 14 is embedded in the annular groove 122; in the front-view state, the central point of the central area 140 of the isolator is directly opposite to the central point of the central pupil area C0 of the cornea; the eyeball E looks at the blue sky or observes a certain distant point through the terminal window 112. When fixing an object, the light entering the inner cavity 10 of the eye mask enters the central pupil area C0 of the cornea at least through the central area 140 of the isolator. The gas pressure from the second inner cavity 10b of the eye mask can press the central area 140 of the isolator toward and contact the central pupil area C0 of the cornea. The central area 140 of the isolator can transmit pressure to the central pupil area C0 of the cornea. Repeated use can prevent the central pupil area C0 of the cornea from protruding outward, and play a myopia relief effect similar to that of hard corneal lenses. When the eyes are closed, the pressure is transmitted to the central pupil area C0 of the cornea through the upper eyelid D1 and the lower eyelid D2. Because the central area 140 of the isolator is in the form of a soft film, it can fully conform to the upper eyelid D1 and the lower eyelid D2, so as to better transmit the pressure. The isolator 14 and the eye mask 1 are preferably detachably combined, and the sterile isolator 14 is preferably used as a consumable material.

[0115] The terminal window 112 of this example is covered with a light-transmitting window 112b, and a beneficial light releasing module 16 is arranged inside the light-transmitting window 112b. The light generated by the light-emitting component or the full-spectrum or other beneficial light releasing module 16 that is beneficial to vision protection or health can enter the user's eyeball E through the fluid channel 110 and then through the cornea C, that is, to guide the user to adjust the position of the eyeball E so that the central pupil area C0 is opposite to the light-transmitting window 112b at the far end of the fluid channel 110 or the open terminal window 112, especially to the center of the light-transmitting window 112b or the terminal window 112. At this time, the external light Coincident with the visual axis A; when the terminal window 112 is blocked and covered and light cannot enter, a light-emitting component (not shown) can be set inside the terminal window 112, especially at a position coincident with the central part of the terminal window 112, and the position of the eyeball E can still be adjusted to make the light generated by the light-emitting component coincide with the visual axis A, and the central area 140 of the isolator of the eye mask inner cavity 10 can be accurately pressed toward the central pupil area C0 of the cornea; the full spectrum or other light that is beneficial to vision protection or health generated by the beneficial light release module 16 enters the eye covered by the eye mask through the fluid channel, and the light properties and intensity can be set individually for each eyeball.

[0116] A spherical, cornea-shaped, or orthokeratology lens-shaped pressing body (not shown) can be placed in the eye mask inner cavity 10, the eye mask first inner cavity 10a, and the eye mask second inner cavity 10b. The pressing body can be preset in a shape that affects the corneal curvature, and the pressing body can be pushed by the fluid to compress the cornea C.

[0117] In the present invention, the direction toward the eyeball E during use is the inner end, the direction close to the eyeball E is the proximal end, and the direction far from the eyeball E is the distal end.

The gas driving unit can be an air pump, a fan, etc. When in use, the external environment air enters the gas purification unit 31 through the gas driving unit 33, then flows through the gas heating and humidification unit 32 to enter the gas delivery channel 30, and then enters the eye mask inner cavity 10 through the fluid communication port 111; Fig. 11BAs shown, the purified, warmed and humidified air enters the eye mask cavity 10 through the gas delivery channel 30. At this time, the negative ion module T releases pure air negative ions through the negative ion release terminal T1, ensuring that the air contacted by the cornea and the surrounding eyeball structure is warm and moist or cool and moist and rich in pure air negative ions; promoting the balance of corneal microecology; air negative ions can remove free radicals generated by light radiation in the cornea.

[0136] The present invention provides a vision training program that can adjust the eyeball to a emmetropia state. The eye can be observed monocularly through the terminal window of the eye mask for as long as possible to see the blue sky or an object 5 meters away, which is helpful to prevent the occurrence of myopia and avoid the aggravation of existing myopia. For myopic people who do not want to undergo surgery and cannot tolerate corneal lenses, the present invention is applied to pressurize the inner cavity of the eye mask in the emmetropia state, and the clean air directly compresses the central pupil area of ​​the cornea or directly or indirectly compresses the central area of ​​the cornea through the central area of ​​the membrane-shaped isolation body, so as to avoid excessive corneal curvature and improve myopia.

[0137] When the inner cavity 10 of the eye mask of the present invention is filled with gas or liquid with a pressure higher than the external environment, such as a pressure of about 4 kPa, the cornea C is directly or indirectly pressed, and the eye mask 1 and the edge portion 12 of the opening in the eye mask are preferably sealed or slightly leaked from the external fluid to ensure that the pressure in the inner cavity 10 of the eye mask is continuously stable or changes only slightly.

[0138] The various fine terminal window adjustment modules and gas control modules of the present invention are integrated on the eye mask bracket to form an extraocular microenvironment system. For each eyeball, not only can it be adjusted to the emmetropia state but also individual parameters can be set. The built-in position and angle sensors assist the first adjustment module to the fourth adjustment module to perform more precise position adjustment. Training such as myopia prevention and control and strabismus correction can be carried out. Various lenses can also be embedded in the inner cavity or fluid channel of the eye mask to correct refractive errors. In addition to use during rest and sleep, it can also be used in various eye-using work to achieve maximum benefit.

[0139] When the present invention does not use the eye mask bracket 2, one or more of the gas control module 3, the first adjustment module 21, the second adjustment module 22, the third adjustment module 23, and the fourth adjustment module 24 connected to the primary extension part 11 or the secondary extension part 13 of the eye mask can be directly operated by hand or fixed on other supporting objects when in use.
