Contact lens care solution containing antioxidant substances and preparation method thereof

Abstract

The invention discloses a contact lens care solution containing antioxidant substances and a preparation method of the contact lens care solution, and belongs to the field of eye health care. The aqueous solution is prepared from the following components: 0.01 to 0.2 weight percent of VC (Vitamin C), 0.01 to 0.2 weight percent of ergothioneine, 0.1 to 2 weight percent of humectant, 0.01 to 0.5 weight percent of antibacterial agent, 0.05 to 0.95 weight percent of buffering agent, 0.01 to 0.1 weight percent of surfactant, 0.35 to 1.0 weight percent of osmotic pressure regulator and 93 to 98 weight percent of water for injection; the pH value of the contact lens care solution is 6-8. According to the contact lens care solution provided by the invention, the VC and the ergothioneine which are obtained by adopting a fermentation process and have no toxic or side effects are used as antioxidants, and the contact lens care solution can be used for improving the oxidation resistance of worn contact lenses and protecting eyes from free radical damage, has an anti-inflammatory repair effect and improves the wearing comfort.

Description

technical field [0001] The invention relates to a contact lens care solution containing antioxidant substances and a preparation method thereof, belonging to the field of eye care. Background technique [0002] According to the research report of the World Health Organization, the number of myopia patients in China has reached 600 million, and the overall myopia rate of teenagers has reached more than 50%. China has become the world's largest myopia country. Eye health is related to the healthy growth of young people, and it is also a major issue related to the future of the country. At present, the vast majority of myopia patients use optical correction, which includes frame glasses and contact lenses. Contact lenses are made according to the shape of the human cornea and are directly attached to the tear layer of the cornea. Widely favored and used by myopia patients. However, contact lenses will prevent the cornea from contacting the air. Wearing them for a long time wi...
