Description

Nano silver perfume contain contact lens}

The present invention relates to a contact lens (100), and the lens is used in detail if it is currently used in the cornea and sclera (鞏膜: black eyes and the white portion around it)

There are a keratoconvex lens to be attached to and a corneal lens to be attached to the cornea.

Scleral lenses do not squeeze or fall off, but they can damage the cornea or sclera if worn for a long time. Almost no corneal lenses are used except in special cases.

The corneal lens is circular and usually has a diameter of 7 to 9 mm and a central thickness of 0.1 to 0.5 mm. Contact lenses were invented in the 1820's, and their widespread use came after the development of the plastics industry after World War II.

At first it was made of glass, but it was easy to break, and it was dangerous. Currently, it is made of safe acrylic resin or silicone, and according to the refractive index of each person, curvature of cornea and size, it is thin plate-shaped by polishing method and mold method. Made with meniscus lens.

Contact lenses are used for medical, professional and cosmetic purposes. Medically, it is used when the vision is not corrected properly unless it is a contact lens. In other words, refractive errors, especially severe myopic astigmatism, and ataxia (a lens removed in the eye by surgery, etc.), including a large difference in the degree of refraction of the left and right eyes. Or when there are irregularities on the surface of the cornea, the cornea (the cornea is deformed into a cone).

It is also used when the glasses are blurred or dangerous in occupation, and they are used to make a good view of the person who does not want to use the glasses cosmetically.

Compared with glasses, the advantage is that the optical axis of the eyes and the lens always coincide.

Because there is no aberration and the refraction of right and left is different, there is no difference in the size of the retinal image so that the object does not appear double or distorted. Even if I am there, the reflection disappears and the eyesight is improved, and the wearing of the lens is seemingly unknown.

Defects are unsuitable for people with special allergies, extreme nervousness, hypersensitivity reactions, and should be used under certain conditions of wear, and have some foreign object or congestion until familiarity.

Do not use if you have eye diseases, especially corneas, conjunctiva, sclera, eyelid diseases, iris or ciliary inflammation. When used for the first time, the ophthalmologist must be thoroughly examined and worn, and the eye disease should be checked well.

The wearing time is extended within 2 hours on the first day and 1 hour from the next day. Once you get used to it, you can usually wear it for 8 to 16 hours, and if you are examined by an ophthalmologist every 3 months, you can prevent eye damage. .

Wearing methods need to be trained under the guidance of an ophthalmologist. The lens is in close contact with the surface tension, and if it becomes cloudy or a rainbow around the lamp is removed, the eyes are rested. When sleeping, the lens must be removed and immersed in saline or preservative solution.

Soft lenses are about 13.0-14.5mm in diameter. It is larger in diameter than hard lenses and consists of materials such as PHEMA (Polyhydroxyethyl Methacrylate) and PVP (PolyVinyl Pyrrolidone). The overall moisture content is about 30-80% of hydrophilicity and the lens itself is soft, so there is less foreign body or corneal pressure when the lens touches, compared to the hard lens;

In addition, the resin is not only optically superior and transparent, but also has adaptability to living bodies. Contact lenses made of PMMA have sufficient stability if they follow the wear rules, but if they are not too tight or sleep without pulling, corneal edema may occur due to oxygen deficiency.

Care should be taken because corneal epithelial erosion may occur.

In addition, the lens completely covers the cornea, increasing resistance to debris and reducing the risk of losing the lens in the face of severe movement. Eye adaptation and comfort are also good, but high-performance soft lenses often feel dry and have a weak material, resulting in poor optical correction and relatively high prices.

Hard lenses are made of harder materials with higher safety than soft lenses. The diameter of the lens is about 8-9.0mm. Good for correcting vision in patients with severe or irregular astigmatism. Longer lifespan, easier to clean than soft lenses, less eye insertion, removal and allergy to solution.

In order to improve the oxygen permeation function of hard contact lenses, physical researches such as making holes in the center of the lens or drilling a lot of thin holes through the laser beam are used for the hard contact lenses. Soft lenses tend to be preferred because of their strength, but they also have the same hard contact lenses for many years because of their excellent resistance and convenient operation management.

The biggest drawback of hard contact lenses is that they do not penetrate oxygen at all, so they cause severe pain in the next day's wear, especially at night and after sleeping.

Next, RGP lenses are intermediate lenses for hard and soft lenses, and the main materials are CAB (Cellulose Acetate Butylate) and silicon. Advances have been made in terms of oxygen permeability and stability, but the strength of the materials, the manufacturing process are difficult and the price is high.

When worn, it is easy to get dirty or blemishes.

The disadvantage of hard lenses is increased oxygen permeability, but in order to increase the amount of oxygen permeation, fine pores should naturally be formed on the surface of the lens, and protein deposits will accumulate in place.

However, because it is kept dry compared to soft lenses, there is less risk of bacteria because there is no moisture in the lens, so the incidence of eye disease is less than that of general soft lens wearers.

Then, the contact lens 100 should always be wet with the above characteristics.

Softness is maintained, and if there is no moisture, it hardens and cracks, which prevents it from being used and the lens itself has no antibacterial or bactericidal properties. People with symptoms can't wear lenses.

Accordingly, an object of the present invention is to solve the problems of the conventional contact lens as described above.

Silver, which is a technique different from conventional silver, is powder in the form of nano silver (NANO SILVER) or

The silver (Ag) solution is compounded (500) to a plastic resin, acrylic resin or rubber silicone, which is a material of the contact lens 100, in a weight ratio of 0.01% to 5%, or the inside or outside of the lens is nanosilver 400 Functional contact lens with sterilization, antibacterial and detoxification by coating 700 with material and mixing or blending with 500 at any constant weight ratio between NANO SILVER 2PPM and 999 PPM. Functional contact lens with nano silver (NANO SILVER) added to manufacture and complete (100) to continue to sterilize lenses that are easy to produce and propagate bacteria or fungi microorganisms and proteins that are dangerous factors for lenses. In providing 100.

The present invention is made of silicone, rubber, plastic resin, or acrylic resin, which is a material of color lenses or contact lenses 100, which are often worn by people with poor eyes, instead of glasses, or colored by lenses for aesthetic reasons. It relates to a contact lens 100 made of.

The first person to think about the concept of the contact lens 100

Leonardo da Vinci, but he never made it.

Ideas were found in his sketches and notes.

In 1637 Rene Descartes invented something similar to the contact lens 100

In practical use, it was not precisely a lens, and in the late 1800's Zurich's doctor Adolf Fick, vial maker Fredrick Muller, and another doctor, Eugene Kalt, made a glass lens that failed.

Then in 1934 a plastic called polymethylmethacrylate (PMMA) was developed

A man named William Feinbloom attempts to make a lens using PMMA and glass. The author of the Corneal contact lens is believed to be Kevin Tuhoy. He made a lens in 1948 and patented it.

Subsequently, the materials that make lenses continue to develop with the development of science

The contact lens 100 has become.

In general, contact lenses are designed so that people with low vision can wear them to the pupils of the eye without wearing glasses that are cumbersome for use for beauty or aesthetic reasons. It can be used in the condition that it is used, and there is no inconvenience caused by wearing the glasses, and it is not recognized in appearance and is used by many people who need the glasses because of low vision. There are many women who wear cosmetics even though their eyes are not bad, and pollutants or dust get on the lens and neglect the disinfection of the lens to cause eye diseases such as conjunctivitis and eye drops.

The contact lens 100 as described above has a size large enough to cover the cornea, and has a hemispherical shape made of soft material so as to be in close contact with the epidermis of the eye. To very thin thickness

It is supposed to be.

Therefore, in the present invention, when using the contact lens 100, such as sweat and secretion

Since various pathogens, such as fungi, fungi, and E. coli, which float, propagate on the surface of the lens, nanosilver 400 powders or liquids are used in the manufacture of lenses to solve various problems such as contamination of various eye diseases and infectious diseases. Injected into (600) to sterilize and antibacterial will be to invent a lens that generates ions.

Accordingly, the present invention has been drawn to solve the above problems,

To help understand, we will briefly describe the nano silver (400).

First, a brief description of the nano silver (NANO SILVER) that is put into the present invention for the purpose of understanding.

The atomic weight of silver is 107.87 and silver (Ag) has been known for a long time.

Nano silver (400), a compound word of our country's Nano-technology and silver, is named nano silver (NANO SILVER), and various products based on nano silver (NANO SILVER), which is composed of powder and solution, are invented many times. It is produced and commercialized.

Nano silver containing silver (NANO SILVER) is a new concept that is made by utilizing the excellent effects such as antibacterial deodorization and prolonging the preservation time of food among the many characteristics of silver.

Regardless of the East and the West, silver has been recognized as a material that not only prevents germs but also disinfects. Nano-silver extraction method is currently used by adding silver (Ag 99.9%) to distilled water and generating low current at low temperature. After electrolysis of the contained compounds, electrophoresis using the + and-poles of each molecule can be used to collect silver (Ag 99.9%) and other physical methods such as liquid reduction and grinding. In order to obtain stable nano silver, many electrolysis methods are used.

Silver ions are used in general sterilization concept machines and disinfectants, and all silver products currently used are silver obtained by decomposition, and the amount of addition is very small. The sterilization power of silver varies depending on the product, but a maximum of 99% can be obtained.

Nano silver (400) is a silver super fine particle of 3 ~ 5nm, directly acting on harmful bacteria, directly dissolving the cell membranes of harmful bacteria, and interfering with the electron transfer system of harmful bacteria to ensure sterilization. = 99.9%) (for reference, VIRUS size is about 10nm).

Nano silver (400), the main antimicrobial mechanism of melting the cell membrane of harmful bacteria to interact with the enzymes in the cell to block the metabolic function of nutrients, that is, nutrients inflow and discharge, and to prevent the respiratory function of harmful bacteria to prevent intracellular APT production It stops the growth and regeneration of harmful bacteria and destroys them.

In addition, the nano silver, because it releases the antibacterial force continuously from the fine particles to control the harmful bacteria, excellent durability of the antibacterial / antibacterial function.

Therefore, the nano silver (400), the resistance does not occur and nano silver is effective to the surface reaction and can kill all the germs 99%, especially in the common E. coli or food poisoning equality.

In addition, since the function must be directly attached to the bacteria, the energy value of the surface is higher than the internal energy value of lactic acid fermented foods or materials accumulated in containers or packaging, and nano-nanolation means that the surface area is expanded.

“The larger the surface area, the smaller the nanoparticles, the better the sterilization and antibacterial activity. Based on the data that have been tested so far, E. coli, yellow staphylococcus, Salmonella, Vibrio, , Typhoid bacteria and the most resistant

MRSA (methicillin resistant Staphylococcus aureus) can be 99.9% antibacterial and bactericidal.

Even if silver (Ag) is present in an ionic state or a metal state, it may be referred to as colloidal silver when it is present in a colloidal state by a solvent.

Nano silver (NANO SILVER) has the best antibacterial activity.

Nanosilver (400) is a super fine particle of pure silver unlike general chemical antimicrobial, so it has excellent antimicrobial / microbial activity (99.9%) even at high temperature, nontoxic, non-irritating and almost all bacteria or viruses It is reported that fungi cannot live in contact with nanosilver for more than 5 minutes.

An object of the present invention is to solve the above conventional problems,

In the present invention, the powder or liquid of the nano silver material may be added to the plastic resin, rubber, acrylic resin, or silicone, which is a raw material of the contact lens 100 during the manufacturing of the contact lens 100, or in the final treatment. Bacteria or viruses that can be transmitted from the lens to the eye by coating (700) or coating the inside or the outside of the lens with the nanosilver 400 (600) or the combination (500) in the weight ratio of ˜5%. It was able to sterilize the fungus and take care of the hygiene and health of the people who are the contact lens users.
