Abstract:Irritation of the eye in the case of contact lens users may imply dry eye syndrome (DES), commonly treated by eye drops. The paper focuses on measuring the friction coefficient with the simultaneous observation of lubricating film formation of the simulated eye/lens/lid interface. The experiments are performed in a pin-on-plate setup under the linear reciprocal motion. The contact is lubricated by twelve different solutions as the potential ingredients for eye drops, focusing on the role of mucin, buffer type,… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
