ABSTRACT:
The present invention provides methods for treating contact lenses and compositions for the same. The present invention includes contacting a lens with an aqueous solution comprising a sulfobetaine compound represented by the formula: ##STR1## wherein: R.sub.1 is an alkyl group having from 8 to 30 carbon atoms, R.sub.2 and R.sub.3 are individually hydrogen or alkyl groups having from 1 to 4 carbon atoms, and R.sub.4 is an alkyl group having from 2 to 6 carbon atoms. In preferred embodiments of the invention, the subject compounds are used in combination with antimicrobial agents for providing simultaneous disinfection and cleaning of contact lenses.
