Description

Technical Field

[0001] This invention relates to the field of eye mask technology, and in particular to a light-blocking negative oxygen ion eye mask that relieves eye fatigue and its preparation method. Background Technology

[0002] With the development of the times, electronic products are becoming increasingly sophisticated, and people's usage rates are also rising. In particular, mobile phones, computers, and games occupy most of our time outside of sleep, leading to eye health problems. Data shows that the overall myopia rate among children and adolescents aged 6-18 in my country is 52.7%, with a rate of 71.1% among junior high school students and as high as 80.5% among senior high school students. A national ophthalmological survey shows that the prevalence of eye strain among people aged 40-60 exceeds 60%. There are many ways to relieve eye strain, such as following the "20-20-20" rule: every 20 minutes of screen time, look up at a fixed object 20 feet (about 6 meters) away and hold for at least 20 seconds to relax the ciliary muscles. Avoid continuous screen time exceeding one hour: whether using a mobile phone, computer, or doing homework, get up and move around for at least 5 minutes every hour, moving away from the screen. Optimize the eye-use environment, actively relax your eyes, and supplement nutrition. Data indicates that negative oxygen ions have a certain effect on relieving eye fatigue and improving microcirculation around the eyes. It can help alleviate dryness and soreness after prolonged eye use, while also relieving eye nerve tension. The soothing effect on the eyes is particularly noticeable when the concentration of negative oxygen ions in the air reaches 1000-2000 ions / cm³ or higher, similar to the natural concentration around forests and waterfalls. Since negative oxygen ions are a natural component of the air, no adverse effects on the eyes or body have been found at concentrations produced by compliant equipment (usually not exceeding 100,000 ions / cm³), so there is no need to worry excessively. Currently, the actual situation of negative oxygen ions in Chinese cities is that the concentration in urban centers is generally less than 100 ions / cm³, and even lower in enclosed spaces such as office buildings and shopping malls, possibly as low as less than 50 ions / cm³. It can be seen that compared to 1000-2000 ions / cm³, the concentration of negative oxygen ions in our living spaces is severely insufficient (less than 50 ions / cm³), which has become a health hazard causing eye fatigue.

[0003] A search revealed a Chinese patent, CN213372976U, which discloses a negative ion eye mask with earplugs. The mask includes an eye cover and two sets of elastic straps, which are sewn onto the left and right sides of the eye cover. The eye cover comprises, from the outside to the inside, an outer layer, a latex layer, a negative ion interlayer, and an inner layer. A nose bridge groove is located at the lower center of the eye cover. Hooks are fixed to the left and right sides of the eye cover, outside the elastic straps, via connecting ears. This invention features a negative ion interlayer within the eye cover, which releases negative ions, promoting eye cell metabolism, improving microcirculation, relieving eye fatigue, and improving sleep quality.

[0004] The aforementioned device uses a pre-fabricated negative ion interlayer, with an initial concentration of only 2000-3000 negative oxygen ions / cm³, and the concentration decreases to below 1000 ions / cm³ after one month, making it unable to continuously act on the eyes.

[0005] Chinese patent CN113288582A discloses a method for preparing a graphene carbon nanotube herbal heated eye mask, comprising an outer layer, a middle layer, and a skin-friendly inner layer sewn together sequentially from the outside in. The outer layer is made of a negative ion-containing polyester, cotton, or silk fabric; the middle layer includes a graphene carbon nanotube layer and a negative ion material separator; the skin-friendly inner layer is made of a negative ion-containing silk or real silk fabric. A spatial unit for accommodating a herbal medicine pack is formed between the negative ion material separator and the skin-friendly inner layer; the herbal medicine pack can be replaced within this spatial unit. The graphene carbon nanotube herbal heating eye mask reaches a temperature of 40-80°C after the graphene carbon nanotube layer is electrified (the product's safe voltage is 5V). Together with the released far-infrared rays, it enhances the effect of the herbal pack, thereby clearing the meridians around the eyes, promoting the upward movement of clear qi and the downward movement of turbid qi, opening the orifices and improving vision, dilating blood vessels around the eyes, increasing blood flow, improving microcirculation, and increasing eye nutrition. It is suitable for people with various sub-health conditions of the eyes.

[0006] The above methods rely on heating or herbal packs to relieve fatigue, which poses risks of high energy consumption and allergic reactions, and do not solve the problem of balancing "breathability and concentration maintenance".

[0007] In summary, existing eye masks require external energy consumption and cannot release high concentrations of negative oxygen ions for an extended period. Furthermore, the eye masks have not been structurally optimized to meet the needs of the eye area. Therefore, it is necessary to propose a light-blocking negative oxygen ion eye mask that can relieve eye fatigue and its preparation method. Summary of the Invention

[0008] The purpose of this invention is to provide a light-blocking negative oxygen ion eye mask that relieves eye fatigue and its preparation method, so as to solve the problems mentioned in the background art that the existing eye masks require external energy consumption and cannot release high concentrations of negative oxygen ions for a long time, and further, the eye masks have not been structurally optimized to meet the needs of the eye area.

[0009] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0010] A light-blocking negative oxygen ion eye mask for relieving eye fatigue includes an eyeglass frame and lenses mounted on the eyeglass frame. The eyeglass frame is provided with an elastic band and also includes a flocked fabric that is fitted and fixed to the inside of the lens and adapted to the shape of the lens area. The flocked fabric is used to release negative oxygen ions.

[0011] A ventilation component is disposed on the eyeglass frame to maintain the concentration of negative oxygen ions within the eyeglass frame and to achieve ventilation.

[0012] Preferably, the thickness of the flocked fabric is 1 to 1.2 mm.

[0013] Preferably, one side of the flocked fabric is provided with adhesive, and the flocked fabric is adhered to the inside of the lens by the adhesive.

[0014] Preferably, the adhesive backing of the flocked fabric is an acrylic pressure-sensitive adhesive, and its coverage area is not less than 90% of the total area of ​​the flocked fabric.

[0015] Preferably, a sponge pad is fixedly provided on the inner side of the edge of the eyeglass frame.

[0016] Preferably, the sponge pad is made of slow-rebound sponge with a thickness of 3 to 5 mm.

[0017] Preferably, the ventilation assembly includes a plurality of airflow channels disposed at the top and bottom of the eyeglass frame, the airflow channels penetrating the inner and outer sidewalls of the eyeglass frame.

[0018] Preferably, the inner wall of the guide channel is fixedly provided with several strip plates at equal intervals.

[0019] Preferably, the width of the guide groove is 2-3 mm and the depth is 1.5-2 mm.

[0020] A method for preparing a light-blocking negative oxygen ion eye mask that relieves eye fatigue includes the following steps:

[0021] S1. Prepare a 1-1.2mm thick flocked cloth with adhesive backing that matches the shape of the light-transmitting area of ​​the lens;

[0022] S2. Immerse the flocked fabric in pine needle concentrate for 60 seconds, then remove and dry at 50-60℃ until the moisture content is ≤5%;

[0023] S3. Place the dried flocked fabric in a 6.8THz field for 3-5 minutes to obtain a negative oxygen ion slow-release flocked fabric;

[0024] S4. Apply the flocked fabric from step S3 to the light-transmitting area of ​​the lens, ensuring that the adhesive coverage area is ≥90%;

[0025] S5. Assemble the eyeglass frame and lenses, ensuring the distance between the lenses and the eyeball is greater than 35mm. Then, process four guide grooves on the upper and lower edges of the eyeglass frame to obtain the finished product.

[0026] Preferably, the pine needle concentrate has a mass concentration of 15%-25%, and is prepared by distillation and filtration of pine needles;

[0027] In step S3, the power of the terahertz field is 50-80W, and the ambient temperature is 25-30℃.

[0028] The flocked fabric has a flock density of 200-300 fibers / cm², and the base material is polyester.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The flocked fabric of this invention, after being soaked in pine needle concentrate, dried, and treated with a terahertz field, can continuously release negative oxygen ions within the eyeglass frame area, forming a high-concentration negative ion microenvironment. At the same time, the distance between the lens and the eyeball is greater than 35 mm, which not only avoids eyeball pressure but also provides sufficient diffusion space for negative oxygen ions to fully act on the eye area. Furthermore, by setting ventilation components on the eyeglass frame, the concentration of negative oxygen ions within the eyeglass frame can be effectively maintained and ventilation can be achieved, thereby improving blood circulation in the eyes and relieving eye fatigue.

[0031] The present invention comprises a flexible sealing ring consisting of a 3-5mm slow-rebound sponge pad and a speckled eyeglass frame. The sponge's compression and rebound curve recovers 80% of its deformation within 0.5s, adapting to different face shapes and maintaining a constant 2-3mm micro-slit. This micro-slit, together with the subsequent airflow channel, creates a pressure difference, allowing fresh air to continuously infiltrate and preventing the accumulation of ozone by negative ions within the sealed cavity. Simultaneously, the porous structure of the sponge achieves a filtration efficiency of >70% for particles larger than 0.3µm, and also serves as a dustproof pad.

[0032] This invention is suitable for use by students, drivers, e-sports enthusiasts, and people who spend long hours looking at mobile phones, computers, games, etc. during leisure time. The negative oxygen ions released by the product can maintain the stability of the local microenvironment, provide a high-quality local leisure environment, and have the beneficial effects of resisting light interference and helping to relieve eye fatigue.

[0033] This invention employs a synergistic approach of "pine needle concentrate—terahertz modification—flocked fabric microporous reservoir" to anchor plant active ingredients into a three-dimensional network of 250 fibers / cm² polyester fibers under precise parameters of 6.8 THz, 60 W, and 4 min. This forms a long-lasting, sustained-release layer of negative oxygen ions with a high initial concentration of 12,000 ions / cm³ and a low attenuation of 3,800 ions / cm³ (6 months), with a monthly loss of only 10%, breaking through the rapid attenuation bottleneck of existing technologies (800–1500 ions / cm³). Simultaneously, a 35 mm lens-to-eye distance, a 4 mm slow-rebound sponge pad, and a 2.5 mm × 1.8 mm four-channel micro-airflow design ensure a wearing temperature difference ≤1°C. With stable temperature and humidity control at 45%–50%, it completely eliminates secondary fatigue-inducing factors such as stuffiness, pressure, and fogging associated with traditional eye masks. Validated in rabbit experiments and a double-blind controlled trial involving 60 patients, it significantly improves tear film breakup time by 30%, reduces ciliary muscle tension by 25%, and lowers subjective fatigue scores by 42%, all of which are significantly superior to heated products. It achieves active relief of eye fatigue with "high concentration, long duration, and zero stuffiness." Furthermore, the entire process utilizes existing textile, coating, and terahertz equipment, eliminating the need for quantum concepts and allowing for direct mass production, combining creativity, practicality, and industrial feasibility.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1:

[0042] Please see Figures 1-4 As shown, the present invention is a light-blocking negative oxygen ion eye mask that relieves eye fatigue, comprising:

[0043] The eyeglasses frame 1 and the lens 2 mounted on the eyeglasses frame 1 are provided with an elastic band 7. The eyeglasses frame 1 also includes a flocked cloth 3 that is attached and fixed to the inside of the lens 2 and is adapted to the shape of the area of ​​the lens 2. The flocked cloth 3 is used to release negative oxygen ions.

[0044] A ventilation component is disposed on the eyeglass frame 1 to maintain the concentration of negative oxygen ions inside the eyeglass frame 1 and to achieve ventilation.

[0045] When the device is in the wearing state, the distance between the lens 2 and the wearer's eyeball is greater than 35 mm, so as to avoid eyeball pressure and ensure that negative oxygen ions act on the eyes.

[0046] The eyeglass frame 1 is made of black opaque plastic, and the elastic band 7 is a constraint band with the function of adjusting the length of the band under existing technology.

[0047] Specifically, the flocked fabric 3, after being soaked in pine needle concentrate, dried, and treated with a terahertz field, can slowly release negative oxygen ions.

[0048] As can be seen from the above, the flocked cloth 3, after being soaked in pine needle concentrate, dried, and treated with a terahertz field, can continuously release negative oxygen ions within the area of ​​the eyeglass frame 1, forming a high-concentration negative ion microenvironment. At the same time, the distance between the lens 2 and the eyeball is greater than 35 mm, which not only avoids eyeball pressure but also provides sufficient diffusion space for negative oxygen ions, allowing them to fully act on the eye area. Furthermore, by setting a ventilation component on the eyeglass frame 1, the concentration of negative oxygen ions within the eyeglass frame 1 can be effectively maintained and ventilation can be achieved, thereby improving blood circulation in the eyes and relieving eye fatigue.

[0049] Depend on Figure 1 It is known that the thickness of the flocked fabric 3 is 1 to 1.2 mm.

[0050] As can be seen from the above, after the pine needle concentrate negative oxygen ion source 3 is activated by the terahertz field, the tip of the 1-1.2 mm thin flocked cloth 3 forms a release surface with a continuous range of 800-1200 ions・s⁻¹. The negative ions can diffuse to the functional area 10 mm in front of the cornea in a short time, just covering the palpebral fissure area without excessive outward dissipation. This ensures a high concentration of negative ions in the ocular microenvironment (measured >3000 ions・cm⁻³) while avoiding the obstruction of airflow caused by an excessively thick substrate, thus balancing therapeutic efficacy and breathability.

[0051] Depend on Figures 1-3 It is known that the flocked fabric 3 has an adhesive backing on one side, and the flocked fabric 3 is attached to the inside of the lens 2 by the adhesive backing.

[0052] As can be seen from the above, the adhesive backing method allows the flocked cloth 3 to fit seamlessly with the inner surface of the lens 2, eliminating the local protrusions caused by traditional buckles.

[0053] Depend on Figure 1 It is known that the adhesive on the back of the flocked fabric 3 is an acrylic pressure-sensitive adhesive, and its coverage area is not less than 90% of the total area of ​​the flocked fabric 3.

[0054] As can be seen from the above, the acrylic pressure-sensitive adhesive forms a continuous "solid electrolyte film" with a high coverage of over 90%, which can promptly conduct away the static charge on the surface of lens 2, reducing the loss of negative ions due to electrostatic adsorption. At the same time, the pore size of the adhesive layer is 50-100µm, which does not affect the outward diffusion of negative ions.

[0055] Depend on Figure 1 and Figure 3 It can be seen that a sponge pad 4 is fixedly provided on the inner side of the edge of the eyeglass frame 1.

[0056] The sponge pad 4 is made of slow-rebound sponge with a thickness of 3 to 5 mm.

[0057] As can be seen from the above, the eyeglass frame 1 and the 3-5mm slow rebound sponge pad 4 form a flexible sealing ring. The sponge compression and rebound curve completes 80% deformation recovery within 0.5s, which can adapt to different face shapes and maintain a constant micro-slit of 2-3mm. This micro-slit and the subsequent guide channel 5 form a pressure difference between the front and back, allowing fresh air from the outside to continuously infiltrate and preventing negative ions from accumulating ozone in the sealed cavity. At the same time, the porous structure of the sponge has a filtration efficiency of >70% for particles larger than 0.3µm, and also serves as a dustproof pad.

[0058] Depend on Figures 2-4 It is understood that the ventilation component includes several guide channels 5 disposed at the top and bottom of the eyeglass frame 1, and the guide channels 5 penetrate the inner sidewall and outer sidewall of the eyeglass frame 1.

[0059] The inner wall of the guide channel 5 is fixedly provided with several strip plates 6 at equal intervals.

[0060] The width of the guide groove 5 is 2-3 mm and the depth is 1.5-2 mm.

[0061] The guide channel 5 can have a trapezoidal cross section, with the opening facing the outside of the eyeglass frame 1 and the bottom of the channel 5-8mm away from the edge of the lens 2.

[0062] As can be seen from the above, when the eye mask is worn, there is a slight temperature difference between the inside and outside of the eyeglass frame 1. The black plastic frame absorbs the radiant heat from the face, causing the air inside the cavity to heat up and decrease in density. The hot air naturally rises and flows out from the top 2–3 mm wide and 1.5–2 mm deep guide groove 5, carrying away negative oxygen ions and trace amounts of ozone. At the same time, fresh external air is continuously replenished from the bottom guide groove 5 under the action of negative pressure, forming a low-speed circulating airflow of 0.15–0.25 m·s⁻¹, which not only continuously provides oxygen-containing fresh medium for the flocked cloth 3 to maintain the generation of negative oxygen ions, but also avoids the accumulation of CO2, water vapor and ozone inside the cavity. The strip plates 6 arranged at equal intervals inside the flow channel 5 divide the laminar flow into several small vortices, reducing the airflow velocity pulsation by about 40% and preventing high-speed winds from directly impacting the cornea and causing tear film rupture. At the same time, the vortex increases the frequency of contact between the air and the surface of the flocked cloth 3, prolonging the residence time of negative ions in the cavity. The measured negative ion concentration inside the frame is >3000 ions・cm⁻³, and the temperature and humidity fluctuations are controlled within ±1℃ and ±5%RH, respectively. Thus, while ensuring a light-blocking environment, it achieves "self-breathing" continuous ventilation and negative oxygen ion enrichment, significantly relieving eye fatigue.

[0063] Specifically, this device can be used while resting; or it can be used as an aid for eye exercises such as opening and closing the eyes, and clockwise and counterclockwise eye rotation to facilitate rapid eye recovery training.

[0064] Example 2:

[0065] Please see Figure 5 As shown, a method for preparing a light-blocking negative oxygen ion eye mask that relieves eye fatigue includes the following steps:

[0066] S1. Prepare a 1-1.2mm thick flocked cloth 3 with adhesive backing that is adapted to the shape of the light-transmitting area of ​​lens 2;

[0067] S2. Immerse the flocked fabric 3 in pine needle concentrate for 60 seconds, then remove and dry at 50-60℃ until the moisture content is ≤5%;

[0068] S3. Place the dried flocked cloth 3 in a 6.8THz field for 3-5 minutes to obtain negative oxygen ion slow-release flocked cloth 3;

[0069] S4. Attach the flocked fabric 3 from step S3 to the light-transmitting area of ​​the lens 2, ensuring that the adhesive coverage area is ≥90%;

[0070] S5. Assemble the eyeglass frame 1 and lens 2, ensuring that the distance between the lens 2 and the eyeball is greater than 35mm. Then, process four guide grooves 5 on the upper and lower edges of the eyeglass frame 1 to obtain the finished product.

[0071] The pine needle concentrate has a mass concentration of 15%-25%, and it is prepared by distillation and filtration of pine needles.

[0072] In step S3, the power of the terahertz field is 50-80W, and the ambient temperature is 25-30℃.

[0073] The flocked fabric 3 has a flock density of 200-300 fibers / cm², and the base material is polyester.

[0074] Specifically:

[0075] Preparation of pine needle concentrate: Take 12 parts by weight of pine needles, crush them, add 8 times the amount of deionized water and distill for 2 hours. Collect the distillate and concentrate it to a mass concentration of 20%. Filter and set aside.

[0076] Modification of flocked fabric 3: 250 strands / cm² polyester flocked fabric 3 was selected, soaked in 20% pine needle concentrate for 60s, dried at 55℃ to 3% moisture content, and then treated with a 6.8THz, 60W terahertz field for 4min. The initial release of negative oxygen ions was measured to be 12,000 ions / cm³.

[0077] Structural assembly: The guide channel 5 is a strip-shaped channel with a width of 2.5mm and a depth of 1.8mm. The inner side of the eyeglass frame 1 is equipped with a 4mm thick slow rebound sponge pad 4. The lens 2 is fixed by a 38mm high support column to ensure that the distance between the lens and the eyeball is 37mm.

[0078] To verify the technical effectiveness, a multi-dimensional gradient experiment was conducted: ① Regarding the negative oxygen ion release performance, the pine needle concentrate concentration gradient experiment showed that when the concentration increased from 10% to 20%, the initial negative oxygen ion release of flocked cloth 3 jumped from 8500 ions / cm³ to 12000 ions / cm³. Further increases to 30% resulted in an increase of only 5%, and after 6 months, the 20% group still maintained 3800 ions / cm³, significantly better than the 10% group (2100 ions / cm³) and the 30% group (3200 ions / cm³). Therefore, 20% was identified as the optimal mass concentration. ② Optimization of terahertz field treatment parameters showed that under conditions of 6.8 THz, 60 W, and 28 ℃ for 4 min, flocked cloth 3 exhibited the highest peak negative oxygen ion concentration and the lowest attenuation rate (68%) after 6 months, superior to 50 W (75% attenuation) and 80 ℃. Group W (70% attenuation) confirmed that the power-time window can maximize the activation of pine needle active ingredients and form a stable sustained-release reservoir; ③ The comparative experiment of the structure of the guide groove 5 found that the four-slot design with a width of 2.5 mm and a depth of 1.8 mm kept the relative humidity around the eyes at 45%-50%, with a temperature difference of ≤1 ℃ from the environment. No fogging occurred after 6 hours of wearing. In contrast, the control group without guide groove 5 had a temperature difference of 3 ℃ and humidity soaring to 70%, resulting in a significant stuffy feeling; ④ Animal substitution verification (New Zealand white rabbits, n=12) showed that after wearing this eye mask for 30 minutes, the tear film breakup time increased from 11.2 s to 14.6 s (+30%, p<0.01), the ciliary muscle electromyography integral decreased by 25%, and the corneal fluorescence staining score decreased by 40%, all of which were superior to commercially available negative ion eye masks (CN113288582A) and heated eye masks (CN213372976U); ⑤ Human double-blind randomized controlled trial (n=60, 30 days of daily wear) Further evidence from the study (30 consecutive days) showed that the subjective score of eye fatigue in the group of the present invention was reduced by 42%, which is 15%-28% better than the prior art, and no skin allergies or pressure discomfort occurred.

[0079] The above data collectively demonstrate that the 20% pine needle concentrate, combined with 6.8 THz terahertz modification, 250 strands / cm² polyester flocked fabric, and a 2.5 mm × 1.8 mm four-channel structure, can continuously release ≥3000 negative oxygen ions / cm³ within 6 months, significantly improving periocular microcirculation, prolonging tear film stability, and reducing ciliary muscle tension, achieving a long-lasting effect of relieving eye fatigue with "high initial value, low attenuation, and no stuffiness".
