The important thing to protect the eyes is to protect the cornea, especially for people who wear contact lenses.
With vision, we can see this colorful world. With vision, we can feel the warmth of mankind. However, the most fragile organs of this person's body are often neglected. We took the liberty of enjoying the beauty it brought to us, but forgot to take care of it. Especially friends who wear contact lenses should pay more attention. In the hot summer, keep everything fresh, remember your eyes
After the birth of contact lenses, we know that they have brought a lot of convenience to our lives, but contact lenses eventually come into direct contact with the cornea, so we must pay special attention to close-fitting clothes that are more particular than jackets. Recent problems with care solutions have also made many contact lens users uneasy. Let's explore how to protect your eyes!
Let's first talk about the cornea. First of all, the cornea is a relatively special tissue in our human body. There are no blood vessels on the crystal clear cornea, so oxygen cannot be sent to the cornea through the blood. In order to maintain normal physiological activity of corneal endothelial cells, oxygen in the air must be absorbed through contact with the air. If contact between the cornea and the air is prevented or hindered, the results are imaginable.
In addition, corneal cells undergo daily metabolism, so metabolites attach to the corneal surface, and their components are mainly proteins. Our tears usually wash the cornea, so these excreted waste has no effect on us. For ordinary invisible glasses, because they are in direct contact with the cornea, the feces cannot be removed immediately. Over time, they will stick to the invisible glasses. That is to say, the protein precipitation we call it, and the results have been quite serious so far.
In order to solve the problem of corneal cells and oxygen permeability, scientists have long developed contact lenses made of silicone hydrogel. Silicone hydrogel adds chemical elements such as silicon and fluorine to ordinary hydrogel to form oxygen and water. The dual channel allows oxygen to directly reach the cornea, making it comfortable and convenient to wear. The oxygen permeability can reach 5-6 times that of ordinary lenses! This not only protects the cornea from damage

In order to solve the problem of protein precipitation, we also have plasma anti-precipitation technology. With it, our cornea can stay fresh! We intervened in plasma technology to form a protective film on the surface of contact lenses. Its thickness is only one-hundred-thousandth of that of a human hair. It is full of charged ions and electrons. Therefore, under the action of biological principles, the deposited protein will be ionized and decomposed.
