Methods for emitting far-infrared rays from contact lenses, and the contact lenses and containers thereof.

Abstract

This invention discloses a method for enabling contact lenses to emit far-infrared rays, as well as the contact lenses and container thereof. This method solves the problems of weakened efficacy due to the distance between the contact lens and the eyeball, and the complexity of the manufacturing process and structure. The invention involves coating a container body with a far-infrared material, placing an immersion solution in a receiving space within the container body, and then immersing the contact lens in the solution. The far-infrared material emits far-infrared rays with a wavelength between 4 and 14 μm into the receiving space. After the contact lens absorbs the far-infrared rays, it is removed from the receiving space to release the far-infrared rays. Experiments have shown that the far-infrared emissivity of the contact lens is between 0.70 and 0.91. This method enables contact lenses to release far-infrared rays while adhering closely to the eyeball, enhancing their health benefits, and reduces manufacturing and structural complexity, achieving a convenient and suitable solution for home use.

Description

Technical Field

[0001] This invention relates to a method for enabling contact lenses to emit far-infrared rays, and to the contact lenses and containers thereof. In particular, it relates to a method and the contact lenses and containers thereof that involve coating the container body of a contact lens container with a far-infrared material, so that the contact lens can absorb the far-infrared rays emitted by the far-infrared material, and thus emit far-infrared rays with wavelengths between 4 and 14 μm when worn close to the eyeball. Background Technology

[0002] In recent years, people's health awareness has generally increased, leading not only to supplement the body's nutritional needs with health supplements, but also to a market for medical products that are beneficial to the human body. Medical research has confirmed that far-infrared rays with wavelengths between 4μm and 14μm resonate with human molecules, promoting blood circulation, enhancing metabolism, and boosting immunity. Therefore, far-infrared rays in this wavelength range are also known as "fertility light" or "fertility rays."

[0003] Therefore, Taiwan Patent Publication No. I293287 proposes a lens that emits far-infrared rays to the eyes to improve eye and periorbital health. This invention uses a material with far-infrared radiating function, such as ceramic powder, and simultaneously adds plasticizers, plastic ester granules, and other plastic polymers, stirring them evenly and mixing them together. After a mixing process, the mixture is fed into an injection molding machine for mold filling, pressure holding, and ejection, thereby producing a finished lens with far-infrared radiating function. The mixing process allows the ceramic powder to be more evenly dispersed within the lens, thereby giving the lens a high transparency.

[0004] However, if the ceramic powder that emits far-infrared energy is mixed with the lens material and then injection molded, and this mixing process is not followed, or if the proportion of the ceramic powder is not precisely adjusted, the light transmittance of the lens with far-infrared radiation function will be reduced, resulting in blurred vision for the user and affecting their safety. In addition, the manufacturing process and lens structure are relatively complex. Furthermore, the distance between the eyeglass lens and the eyeball reduces the health benefits of far-infrared rays for the eyes. Summary of the Invention

[0005] Therefore, in order to improve the efficacy of eye care and reduce the complexity of the manufacturing process and structure, the purpose of this invention is to provide a method for emitting far-infrared rays from contact lenses, as well as the contact lenses and containers thereof.

[0006] To achieve the above objectives, the present invention employs the following technical means:

[0007] This invention provides a method for making contact lenses emit far-infrared rays, the steps of which include:

[0008] A container body is coated with a far-infrared material;

[0009] An immersion solution and a contact lens are placed in a accommodating space of the container body;

[0010] The far-infrared material emits far-infrared rays with a wavelength between 4 and 14 μm into the accommodating space;

[0011] In this way, after the contact lens absorbs the far-infrared rays, it can release far-infrared rays with a wavelength between 4 and 14 μm when it is removed from the containing space, and the far-infrared emissivity of the contact lens is between 0.70 and 0.91.

[0012] Preferably, the far-infrared material is applied to an inner surface and / or an outer surface of the container body.

[0013] Preferably, the far-infrared material comprises a far-infrared powder and an adhesive, wherein the far-infrared powder accounts for 5 to 30 wt% of the far-infrared material, and the adhesive accounts for 70 to 95 wt% of the far-infrared material.

[0014] Preferably, the far-infrared powder is one or a combination of ceramic powder, bamboo charcoal powder, tourmaline powder, germanium powder, titanium powder, graphene powder, nano copper powder, cordierite powder, and mullite powder.

[0015] Preferably, the adhesive is one or a combination of a natural resin and a synthetic resin.

[0016] Preferably, the contact lens is placed in the receiving space for a period of 4 to 24 hours.

[0017] Preferably, when the contact lens is placed into the receiving space, the container body is further kept in an environment at a default temperature, which is between 40 and 80°C.

[0018] Preferably, before or after the container body is covered with the far-infrared material, the container body and an energy material are further placed together in a heated space with a temperature between 35 and 90°C for a period of 2 to 24 hours.

[0023] The far-infrared material is coated on the container body;

[0024] The far-infrared material emits far-infrared rays with wavelengths between 4 and 14 μm into the accommodating space.

[0025] Preferably, the container body is a personal contact lens storage case or a contact lens sealing case.

[0026] The present invention also provides a contact lens that emits far-infrared rays, made by the method for emitting far-infrared rays from a contact lens as described in the present invention.

[0027] Preferably, the contact lens further contains an ultraviolet absorber, enabling the contact lens to resist ultraviolet radiation.

[0032] The following effects can be achieved based on the above technical features:

[0033] 1. The container body is covered with far-infrared material, which can emit far-infrared rays. This allows the contact lenses placed in the container body to emit far-infrared rays with wavelengths between 4 and 14 μm that are beneficial to the human body after they are removed from the container body. The average far-infrared emissivity of the contact lenses is 0.86, and the maximum emissivity can reach 0.91.

[0034] 2. When not wearing contact lenses, simply place them into the container containing the soaking solution. The container is coated with far-infrared material, which not only moisturizes and disinfects through the soaking solution, but also enables the contact lenses to release far-infrared rays. The process is simple and time-saving, and suitable for the user's daily habits.

[0035] 3. When users wear contact lenses that emit far-infrared rays, the lenses adhere closely to the eyeball, enhancing eye health benefits and promoting oxygen supply and blood circulation around the eyes, effectively improving and preventing eye problems.

[0036] 4. Placing the energy material and the container body in the heated space for a certain period of time can enhance the release of far-infrared rays by the container body, thereby improving the efficiency of the contact lenses in absorbing far-infrared rays.

[0037] 5. Contact lenses contain UV absorbers and blue light absorbers, which protect the eyes from UV and blue light damage when worn. In particular, they can block more than 95% of UV rays with wavelengths between 280 and 315 nm.

[0038] 6. Contact lenses that emit far-infrared rays do not contain any far-infrared materials, so vision is not affected after wearing them, and the light transmittance can reach over 90%.

[0039] 7. Regardless of whether contact lenses are clear, colored, daily disposable, monthly disposable, quarterly disposable, or yearly disposable, any type of contact lens can emit far-infrared rays by using a container body coated with far-infrared material. Attached Figure Description

[0049] The present invention will be further described below with reference to specific embodiments, and the advantages and features of the present invention will become clearer as a result. However, these embodiments are merely exemplary and do not constitute any limitation on the scope of the present invention. Those skilled in the art should understand that modifications or substitutions can be made to the details and form of the technical solutions of the present invention without departing from the spirit and scope of the present invention, but all such modifications and substitutions fall within the protection scope of the present invention.

[0050] Please refer to the following first. Figure 1 and Figure 2 This invention demonstrates a method for emitting far-infrared rays from contact lenses, along with the contact lenses and container. The method includes a container body 1, a far-infrared material 2, an soaking solution 3, and a contact lens 4. The container body 1 has a receiving space 11, an inner surface 12, and an outer surface 13. The far-infrared material 2 comprises an adhesive 21 and a far-infrared powder 22. The inner surface 12 and / or the outer surface 13 of the container body 1 are coated with the far-infrared material 2. The contact lens 4 is placed inside the receiving space 11 after the soaking solution 3 is poured into it. In this embodiment, both the inner surface 12 and the outer surface 13 are coated with the far-infrared material 2.

[0051] Specifically, the container body 1 is a personal contact lens storage case or a contact lens sealing case; the adhesive 21 accounts for 70-95 wt% of the far-infrared material 2, and the far-infrared powder 22 accounts for 5-30 wt% of the far-infrared material 2. The adhesive 21 is a natural resin that is a semi-solid or solid organic colloid secreted by animals or plants, or a synthetic resin. The far-infrared powder 22 is a powder or material with far-infrared radiation energy, such as ceramic powder, bamboo charcoal powder, tourmaline powder, germanium powder, titanium powder, graphene powder, or nano-copper. The contact lens 4 may contain one or a combination of powder, cordierite powder, and mullite powder, but is not limited to these. The soaking solution 3 is a contact lens care solution or contact lens-specific solution used for moisturizing, cleaning, and sterilizing contact lenses. The contact lens 4 may be colored or transparent daily, monthly, quarterly, or yearly disposable, with a light transmittance of over 90%. Furthermore, ultraviolet absorbers and blue light absorbers are added to the contact lens 4 to resist ultraviolet radiation and blue light radiation. The effect of blocking ultraviolet rays with wavelengths between 315 and 380 nm reaches 50%, and the effect of blocking ultraviolet rays with wavelengths between 280 and 315 nm reaches over 95%.

[0052] Please see Figures 2 to 4The illustration shows a first embodiment of the invention, in which an energy material 5 and the container body 1 are first placed together in a heating space 6 with a temperature between 35 and 90°C for 2 to 24 hours. Then, the far-infrared powder 22 is coated onto the inner surface 12 and the outer surface 13 of the container body 1 using an adhesive 21. The energy material 5 is a mineral or energy stone with far-infrared radiant energy, such as one or a combination of maifanite, crystal, granite, tourmaline, serpentine, dolomite, bamboo charcoal, and terahertz energy stone, but is not limited thereto.

[0053] Please see Figure 2 , Figure 3 and Figure 5 This invention demonstrates a second embodiment. In this embodiment, the far-infrared powder 22 is first coated onto the inner surface 12 and outer surface 13 of the container body 1 using the adhesive 21. Then, the container body 1 coated with the far-infrared material 2 and the energy material 5 are placed together in a heating space 6 with a temperature between 35 and 90°C for 2 to 24 hours. The energy material 5, as in the first embodiment, can be a mineral or energy stone with far-infrared radiation energy, such as maifanite, crystal, granite, tourmaline, serpentine, dolomite, bamboo charcoal, or terahertz energy stone, or a combination thereof, but is not limited to these.

[0054] After either the first or second embodiment is executed, the soaking solution 3 is then placed into the accommodating space 11 of the container body 1, and then the contact lens 4 is placed in. At the same time, the far-infrared material 2 covering the container body 1 will release far-infrared rays with a wavelength between 4 and 14 μm into the accommodating space 11. The contact lens 4 is immersed in the container body 1 covered with the far-infrared material 2 and kept at a default temperature between 40 and 80°C for a placement time between 4 and 24 hours. The contact lens 4 will absorb the far-infrared rays, and when the contact lens 4 is removed from the accommodating space 11, the contact lens 4 itself can release far-infrared rays with a wavelength between 4 and 14 μm.

[0055] Please see Figure 6 and Figure 7 The diagrams show the relationship between far-infrared emissivity and wavelength for the contact lens 4 described in this invention and existing ordinary contact lenses, respectively. Please refer to the accompanying diagrams. Figure 2Overall, the present invention involves covering the container body 1 with the far-infrared material 2 and placing the soaking liquid 3 in the accommodating space 11 of the container body 1, forming a contact lens container capable of holding the contact lens 4 and allowing the contact lens 4 to absorb the far-infrared rays. This allows the contact lens 4 to release far-infrared rays with wavelengths between 4 and 14 μm after being removed from the accommodating space 11. Furthermore, at a temperature of 40°C, the far-infrared emissivity of the contact lens 4 is between 0.70 and 0.91, with an overall average emissivity of 0.86. In contrast, existing contact lenses that do not implement the method of far-infrared ray release of the present invention can only release far-infrared rays with wavelengths between 6 and 14 μm. At the same temperature of 40°C, the far-infrared emissivity of existing contact lenses is only between 0.76 and 0.79, with an overall average emissivity of 0.78. Experiments have confirmed that the method, container, and contact lens of this invention for releasing far-infrared rays from contact lenses effectively transform ordinary contact lenses into contact lenses 4 capable of releasing far-infrared rays. The far-infrared emissivity of the contact lens 4 can reach up to 0.91, enhancing the eye health benefits when worn close to the eyeball. It also features easy implementation steps and is suitable for any user to operate.
