Problems solved by technology

Because deposits will remain on the surface of the lens that is not cleaned completely, when direct sterilization, the bactericidal ingredients will only combine with the sediments, and cannot combine with pathogenic bacteria, so that the bactericidal ingredients will not be able to play a bactericidal effect

Abstract

The invention discloses a contact lens care solution with good sterilizing effect. The contact lens care solution is composed of the following components in percentage by weight: 0.1-2% of cellulose, 0.05-0.5% of biguanide polycyclic ethane, 0.05-1% of polyhexamethylene guanidine, 0.1-2% of boric acid, 0.01-0.2% of borax, 0.1-3% of borneol, 1-3% of ethanol, and the balance of distilled water. A preparation method of the contact lens care solution comprises the following steps of: (1) heating up biguanide polycyclic ethane and polyhexamethylene guanidine to 40 DEG C according to a proportion for dissolution; (2) dissolving borneol with ethanol, then adding borneol to a solution of the step (1); (3) adding cellulose, boric acid and borax to the above solution, heating up to 85 DEG C, fully stirring and mixing, then filling to a closed container, standing at the room temperature for 24 hours, and sterilizing for 1 hour; and (4) filling the sterilized and cooled solution to a sterile eye drop bottle.

Description

technical field [0001] The invention relates to a contact lens care solution. Background technique [0002] Contact lens care solution is mainly used for cleaning, disinfecting, and removing protein of biological materials, and it is undoubtedly essential for people who wear contact lenses. The deposits and pathogenic bacteria on the surface of the lens must be removed with a care solution first, so that the subsequent sterilizing preservation can be carried out effectively. Because deposits will remain on the surface of the incompletely cleaned lens, when direct sterilization, the bactericidal ingredients will only combine with the sediments, but not with the pathogenic bacteria, so the bactericidal ingredients will not be able to play a bactericidal effect. Contents of the invention [0003] The object of the present invention is to provide a kind of contact lens care solution with good bactericidal effect in order to overcome the above-mentioned deficiencies in the pri...
