This is a non-interventional/observational study designed as a retrospective chart review. Study sites will identify charts within their existing databases in a fair and consistent manner, e.g., reviewing all eligible charts in reverse chronological order by year of baseline visit. The baseline visit will be defined as the first office visit where an eye care practitioner provided an in-person office biomicroscopy exam to the patient, before or during which a contact lens prescription for the study or comparator contact lenses was released. Subjects meeting the eligibility criteria will be enrolled in the study.
