Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an eye shield for wearing orthokeratology lenses. Background Technology

[0002] Orthokeratology lenses reshape the cornea using a corneal reshaping technique. This involves quantitatively correcting the curvature of the cornea through lens reshaping, thus temporarily correcting refractive errors. This non-invasive vision correction method does not involve surgery. Orthokeratology lenses are typically worn overnight while sleeping, usually for 8-10 hours. Under the lens's influence, the central area of ​​the cornea flattens, temporarily reducing myopia. During the day, after removing the lenses, teenagers can achieve clear vision without glasses. Many teenagers also wear sleep masks to improve sleep quality and reduce environmental disturbances.

[0003] Currently, to ensure good light-blocking properties, most eye masks on the market come into contact with the user's eyeballs, sometimes even putting slight pressure on them. This can cause pressure on the orthokeratology lenses worn by teenagers, potentially leading to poor blood circulation in the eyes. Over time, this may cause eye pain or discomfort, significantly reducing the vision-correcting effect of orthokeratology lenses on teenagers. Utility Model Content

[0004] The technical problem this invention aims to solve is that traditional eye masks can cause eye pain or discomfort in teenagers when they wear orthokeratology lenses, greatly reducing the corrective effect of orthokeratology lenses on teenagers' vision.

[0005] To address the aforementioned technical problems, this utility model provides an eye mask for wearing orthokeratology lenses, comprising an eye mask body and a support frame; the eye mask body covers the outer periphery of the patient's eye and is used to block external light; the support frame is disposed inside the eye mask body, and a protrusion is provided on the support frame in a direction away from the patient's eye, and a cavity for placing the orthokeratology lens is formed within the protrusion; when the patient wears the eye mask body, there is a gap between the inner wall of the cavity and the orthokeratology lens worn by the patient.

[0006] In one embodiment, the eye mask body includes a self-heating layer and a silk fabric layer, the self-heating layer being disposed inside the silk fabric layer, and the side of the self-heating layer facing away from the silk fabric layer being in contact with the patient's skin.

[0007] In one embodiment, the eye mask body also includes ventilation holes disposed on the silk fabric layer and penetrating the self-heating layer to dissipate excess heat.

[0008] In one embodiment, the self-heating layer is made of bioceramic fiber.

[0009] In one embodiment, a thickened layer is provided at the edge of the goggle body, which is in contact with the skin around the patient's eyes to isolate light from the edge of the goggle body.

[0010] In one embodiment, an elastic headband is also included, which is wrapped around the periphery of the patient's eyes and connected to the eye mask body to secure the eye mask body to the periphery of the patient's eyes.

[0011] In one embodiment, headband buckles are provided at both ends of the goggle body near the elastic headband, and the headband buckles engage with the elastic headband. The goggle body is detachably connected to the elastic headband through the headband buckles.

[0012] In one embodiment, the cavity is circular and has a diameter of 35mm to 40mm.

[0013] Compared with the prior art, the beneficial effects of the eye mask for wearing orthokeratology lenses according to this utility model embodiment are as follows: 1) The main function of the eye mask body is to block external light, ensuring that the patient can be in a relatively dark environment when wearing orthokeratology lenses for nighttime correction treatment, which helps to improve the correction effect and comfort; 2) The support frame is located inside the eye mask body, which plays a role in fixing and supporting. This design not only maintains the overall structural stability of the eye mask, but also ensures that the orthokeratology lens can be accurately positioned on the patient's eyeball. The protrusion is set on the support frame, away from the direction of the patient's eye, and forms a cavity specifically for placing the orthokeratology lens. This design allows the orthokeratology lens to be placed stably without directly contacting the patient's eyelid, avoiding pressure on the patient's eyeball when wearing the eye mask. There is a gap between the inner wall of the cavity and the orthokeratology lens. This design takes into account the slight displacement that the orthokeratology lens may undergo during the wearing process due to tear secretion, eye movement and other factors. The existence of the gap ensures the freedom and comfort of the lens.

[0014] The eye mask provided in this embodiment of the invention allows adolescent patients to enjoy a good light-blocking effect when wearing it, while the orthokeratology lens can perform its corrective function without external interference. Attached Figure Description

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] like Figures 1 to 4 As shown, the present invention preferably provides an eye mask for wearing orthokeratology lenses, which includes an eye mask body 1 and a support frame 2; the eye mask body 1 covers the outer periphery of the patient's eye and is used to block external light; the support frame 2 is disposed inside the eye mask body 1, and a protrusion 21 is provided on the support frame 2 in a direction away from the patient's eye, and a cavity for placing the orthokeratology lens is formed in the protrusion 21. When the patient wears the eye mask body 1, there is a gap between the inner wall of the cavity and the orthokeratology lens worn by the patient.

[0027] Based on the above technical features, this utility model, through the design of the eye mask body 1, whose main function is to block external light, ensures that the patient can be in a relatively dark environment when wearing orthokeratology lenses for nighttime corrective treatment, which helps to improve the corrective effect and comfort. Through the design of the support frame 2, the support frame 2 is located inside the eye mask body 1, which plays a role in fixing and supporting. This design not only maintains the overall structural stability of the eye mask, but also ensures that the orthokeratology lens can be accurately positioned on the patient's eyeball. The protrusion 21 is set on the support frame 2, facing away from the direction of the patient's eye, and has a cavity specifically for placing the orthokeratology lens. This design allows the orthokeratology lens to be placed stably without directly contacting the patient's eyelid, avoiding pressure on the patient's eyeball when wearing the eye mask. There is a gap between the inner wall of the cavity and the orthokeratology lens. This design takes into account the slight displacement that the orthokeratology lens may undergo during the wearing process due to tear secretion, eye movement, and other factors. The existence of the gap ensures the freedom and comfort of the lens.

[0028] As some embodiments of this utility model, such as Figures 1 to 2As shown, the main body 1 of the eye mask includes a self-heating layer 12 and a silk fabric layer 11. The self-heating layer 12 is disposed inside the silk fabric layer 11, and the side of the self-heating layer 12 facing away from the silk fabric layer 11 is in contact with the patient's skin. The silk fabric layer 11 serves as the outer layer of the main body 1 of the eye mask. Silk fabric is known for its softness, smoothness, and breathability. It not only feels comfortable to the touch and reduces friction on the skin around the eyes, but also helps keep the eye area dry, avoiding the stuffiness caused by prolonged wear. Silk fabric also has certain antibacterial properties, which helps maintain eye hygiene. The self-heating layer 12 is disposed inside the silk fabric layer 11. The main function of the self-heating layer 12 is to absorb the heat released by the body and reflect it back to the skin in the form of far-infrared rays, thereby achieving gentle heating to provide heat therapy to the eyes. This heat therapy can promote blood circulation in the eyes and relieve eye fatigue. Meanwhile, the side of the self-heating layer 12 facing away from the silk fabric layer 11 is designed to fit closely to the patient's skin to maximize the heat therapy effect. This fit design ensures both tightness and comfort when wearing, avoiding discomfort caused by pressure.

[0029] As some embodiments of this utility model, such as Figures 1 to 2 As shown, the main body 1 of the eye mask also includes ventilation holes, which are located on the silk fabric layer 11 and extend through the self-heating layer 12 to dissipate excess heat. The ventilation holes, located on the silk fabric layer 11 and extending through the self-heating layer 12, allow excess heat and moisture inside the eye mask to be directly discharged through these small holes, without slowly diffusing through other parts of the eye mask. To optimize ventilation, the ventilation holes are arranged in a uniform distribution to ensure that excess heat in all areas of the eye mask can be effectively dissipated.

[0030] As some embodiments of this utility model, such as Figures 1 to 2 As shown, the self-heating layer 12 is made of bioceramic fiber. Bioceramic fiber is a functional material composed of ceramic particles and fibers. It can absorb heat emitted by the human body and continuously release heat. Its heating is indirect and constant-temperature, generally maintained at 37℃-39℃, close to human body temperature, making it very suitable for use close to the skin. Because it does not rely on electricity or chemical reactions to generate heat, the temperature will not rise suddenly or overheat. Unlike other heating materials, bioceramic fiber can maintain its function for a long time without the need for electricity. Its natural heating method is suitable for children to wear at night, ensuring a comfortable temperature for their eyes and face while also ensuring safety.

[0031] As some embodiments of this utility model, such as Figures 1 to 3As shown, a thickened layer 14 is provided at the edge of the eye mask body 1. The thickened layer 14 fits snugly against the skin around the patient's eyes to isolate light from the edge of the eye mask body 1. The main function of the thickened layer 14 is to isolate light from the edge of the eye mask body 1, ensuring that the user is in a completely dark environment when wearing the eye mask. This is crucial for promoting eye relaxation, improving sleep quality, and enhancing the corrective effect of orthokeratology lenses. By closely fitting the skin around the eyes, the thickened layer 14 effectively prevents the penetration of external light, providing the user with a more private and quiet sleep environment.

[0032] As some embodiments of this utility model, such as Figures 1 to 4 As shown, it also includes an elastic headband 3, which is wrapped around the patient's eyes and connected to the eye mask body 1 to fix the eye mask body 1 to the patient's eyes. The elastic headband 3, wrapped around the patient's eyes and connected to the eye mask body 1, forms a stable support system. This design ensures that the eye mask body 1 fits snugly against the skin around the eyes, maintaining its position even when turning over or engaging in other activities during sleep. This provides the user with a continuous and stable light-blocking environment, helping to improve sleep quality. At the same time, the design of the elastic headband 3 makes the eye mask suitable for people of different ages and genders. Whether adults or children, regardless of head circumference, users can find the most suitable wearing method by adjusting the tightness of the elastic headband 3.

[0033] As some embodiments of this utility model, such as Figures 1 to 4 As shown, the goggles body 1 has headband buckles 13 at both ends near the elastic headband 3. The headband buckles 13 engage with the elastic headband 3, allowing the goggles body 1 to be detachably connected to the elastic headband 3. The headband buckles 13 allow for a detachable connection between the goggles body 1 and the elastic headband 3, enabling patients to easily separate or combine the goggles body 1 and the elastic headband 3 as needed. This facilitates cleaning, replacement, or adjustment of the goggles' size, increasing the goggles' flexibility and durability. Simultaneously, the headband buckles 13 engage with one end of the elastic headband 3, ensuring a stable connection and effectively preventing the goggles from falling off or shifting.

[0034] In some embodiments of this invention, the cavity is circular with a diameter of 35mm to 40mm. Based on the average distance between the superior and inferior orbital rims of children aged 9-12, a cavity diameter of 35mm to 40mm ensures that the eye patch can completely cover the orthokeratology lens worn by the patient without being too tight or too loose. This design helps to provide a stable and light-blocking wearing environment, preventing the orthokeratology lens from putting pressure on the patient's eyeball.

[0035] Compared with the prior art, the beneficial effects of the eye mask for wearing orthokeratology lenses according to this utility model embodiment are as follows: 1) The main function of the eye mask body 1 is to block external light, ensuring that the patient can be in a relatively dark environment when wearing orthokeratology lenses for nighttime correction treatment, which helps to improve the correction effect and comfort; 2) The support frame 2 is located inside the eye mask body 1, which plays a role in fixing and supporting. This design not only maintains the overall structural stability of the eye mask, but also ensures that the orthokeratology lens can be accurately positioned on the patient's eyeball. The protrusion 21 is set on the support frame 2, away from the direction of the patient's eye, and has a cavity specifically for placing the orthokeratology lens. This design allows the orthokeratology lens to be placed stably without directly contacting the patient's eyelid, avoiding pressure on the patient's eyeball when wearing the eye mask. There is a gap between the inner wall of the cavity and the orthokeratology lens. This design takes into account the slight displacement that the orthokeratology lens may undergo during the wearing process due to tear secretion, eye movement and other factors. The existence of the gap ensures the freedom and comfort of the lens. The eye mask provided in this embodiment of the invention allows adolescent patients to enjoy a good light-blocking effect when wearing it, while the orthokeratology lens can perform its corrective function without external interference.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
