Abstract:
Disclosed is a composition for soft contact lenses which enables to suppress adsorption of a basic chemical substance onto a soft contact lens. This composition for soft contact lenses comprises (A) a basic chemical substance selected from amines having a secondary amino group and/or a tertiary amino group and salts thereof, and (B) one or more substances selected from amino acids and salts thereof, acid mucopolysaccharides and salts thereof and cyclodextrin, while having a pH of 3.5 to 4.8. Also disclosed is a method for suppressing adsorption of the basic chemical substance onto a soft contact lens.
