Sponsor's own description

This study is a randomized, contralateral, investigator-masked non-dispensing study, to investigate the microbial contamination rates on the back surface of two types of soft contact lenses (hydrogel and silicone hydrogel) extracted from Smart Touch Technology blister packs versus conventional lens packaging after short-term placement on the eye, and to compare the microbial contamination rates of the worn contact lenses to those on the participants' hands/fingers used to conduct lens insertion.
