LENS CARE COMPOSITIONS HAVING A PERSISTENT CLEANING EFFICACY

摘要

The present invention provides a lens care composition having a persistentcleaning-efficacy characterized by substantially maintaining the lighttransmittance at around 280 nm of a contact lens after at least 15 cycles ofsoiling with a soiling solution containing proteins and subsequent cleaningwith the lens care composition of the invention. The lens care compositioncomprises at least one surfactant, a polyvinylpyrrolidone (PVP), a celluloseether, and xylitol, wherein in combination with polyvinylpyrrolidone (PVP), acellulose ether, and xylitol, the surfactant provides the persistent cleaning-efficacy.
