摘要

An ophthalmic solution or contact lens solution comprising at least one germicidal/preservative component selected from biguanides and quaternary ammonium salts . The ophthalmic solution further comprises at least one selected amino-acid-based component, 0-0.2wt.% of sodium chloride, and 0-0.5wt.% of phosphate. The contact lens solution further comprises at least one selected acidic component and 0-0.2wt.% of sodium chloride. Alternatively, the contact lens solution further comprises at least one selected amino-acid-based component, at least one selected acidic compound which has at least one carboxyl group or at least one phosphoric acid group, and 0-0.2wt.% of sodium chloride.
