Problems solved by technology

Most of the contact lens care solutions contain disinfectant ingredients such as chlorhexidine and geeramine, which are harmful to the eyes
In addition, the moisturizing function of the existing contact lens care solution is not enough, the lens is easy to dry, and the oxygen permeability is low. After wearing the lens, the user is prone to problems such as dry eyes, inflammation and redness.
Moreover, the main components of existing contact lens care solutions are sodium chloride and preservatives, etc., which are mainly used for cleaning, disinfection, and protein removal of biological materials. Contact lens care solutions are used by contact lens families every day. The deposits and pathogenic bacteria on the surface must be removed with a care solution first, so that the next sterilization preservation can be carried out effectively
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
