Abstract

To provide a liquid preparation for contact lens wherein: the liquid preparation for contact lens assures an excellent disinfecting effect and a sufficiently high degree of safety to the eyes of the lens wearer; the liquid preparation for contact lens does not adversely affect the contact lens, such as a change of the size of the contact lens; and the liquid preparation for contact lens advantageously restrains a generation of deposits on the lens. The liquid preparation for contact lens is prepared, so as to comprise: at least one disinfectant selected from the group consisting of germicidal biguanides and germicidal quaternary ammonium salts (component A); glycolic acid and / or asparatic acid (component B); and 2 ۥ amino ۥ 2 ۥ methyl ۥ 1, 3-propanediol or a salt thereof (component C), wherein the component B and the component C fulfill a predetermined molar ratio.

Description

technical field [0001] The present invention relates to a liquid preparation for contact lenses, in particular to a sterilizing solution for contact lenses, a sterilizing cleaning solution for contact lenses, a sterilizing preservation solution for contact lenses, a sterilizing cleaning preservation solution for contact lenses, etc. liquid formulations used. Background technique [0002] So far, contact lenses are divided into non-aqueous contact lenses and aqueous contact lenses, or hard contact lenses and soft contact lenses, or non-ionic contact lenses and ionic contact lenses according to their materials. Moreover, when any of the above-mentioned contact lenses are used continuously, microorganisms such as bacteria adhering to the surface of the lens may proliferate during the period when the contact lens is taken out from the eye for storage, so it is usually necessary to disinfect the contact lens before use. Sexual contact lenses, bacteria and other microorganisms ar...
