The objective of the study is to compare the clinical performance of two different daily disposable, SiHy toric contact lens types, Lens A and Lens B, in existing soft lens wearers when worn for one week each.
This study is a prospective, bilateral eye, double-masked, randomized, 1-week cross-over, daily-wear design involving two different daily disposable toric lens types. Each lens type will be worn for approximately one week, during which participants record their subjective lens-wear experience.
