Daily Disposable Soft Contact Lenses

This study will enroll 63 eligible subjects (126 eligible eyes, complete at least 108 evaluable eyes) in approximately 6 different medical centers in Taiwan, in order to evaluate the efficacy and safety of ST-1 silicone hydrogel daily disposable soft contact lenses (ST-1 lenses) compared to Miru 1day UpSide. Enrolled subjects will be randomized in a 2:1 test to control ratio at Visit 1. Each site will enroll 8 (intended minimum) to 12 (intended maximum) subjects. In order to eliminate the bias, the Investigators and the evaluators will be masked to the treatment assignment of the randomization code. During the study, the Investigator(s) will examine the ocular health via inquiry, slit lamp biomicroscopy (SLB), visual acuity (VA) test, keratometry, and refractive changes. The Investigator(s) will check ocular health and evaluate the inclusion/exclusion criteria of subjects at screening. After entering the study, subjects will be required to wear the lenses on a daily basis, record daily wearing time on a diary, return to the study site at scheduled visits for evaluations and complete the self-assessment questionnaire at Visit 2 to Visit 7 (1 day, 1 week, 2 weeks, 1 month, 2 months, 3 months).
