A disinfecting and/or preserving solution for contact lenses is disclosed. The disinfecting solution is an aqueous solution containing 0.0035 to 0.04 weight percent of an amphoteric surfactant in combination with 0.0005 to 0.01 weight percent of chlorhexidine and 0.002 to 0.025 weight percent of a non-ionic surfactant, optionally together with up to 0.5 weight percent of thimerosal or other enhancers and optional buffers and the like. The binding (or uptake) of preservative by a hydrophilic soft contact lens is reduced by this invention. |
