Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of contact lens care, and particularly relates to a protein-removing care solution for corneal contact lenses. Background Art
[0002] Corneal contact lenses, commonly known as contact lenses, are medical devices used to correct refractive errors of the human eye. All along, after long-term wearing of corneal contact lenses, deposits will appear on the lens surface. The deposits generally come from tear secretions, physical and chemical products and foreign substances in the surrounding environment. The specific types of deposits generally include biofilms, protein deposits, lipid deposits, inorganic salts, pathogenic microorganisms, etc. On the one hand, a large number of deposits will change the fitting characteristics of the lens, and on the other hand, it will cause different degrees of pathological changes in the eyes, resulting in eye infections and inflammations in users. Therefore, the care of contact lenses is essential, and it is necessary to regularly use a care solution to clean and disinfect the lenses.
[0003] At present, the conventional care method is mainly to soak - rub - rinse with a multi-functional care solution or hydrogen peroxide, plus protein removal once a week. The method is to put the OK lens in the AB mixture for 30 minutes, take it out and rub and rinse repeatedly to complete each protein removal care process. The method is a bit cumbersome. If it is not washed clean, the care solution will remain. The most crucial thing is that it is impossible to achieve thorough cleaning and sterilization. There is even a risk that the lens fades, is rubbed excessively and deformed or damaged due to forgetting the time. In view of this, we have proposed a protein-removing care solution for corneal contact lenses. Summary of the Invention
