Outcomes
Primary Outcome Measures
Comfort
Wearing comfort (throughout the day) for stenfilcon A and etafilcon A toric lens pair is assessed. Scale 0-10, 0= extremely uncomfortable cannot wear at all, 10=very comfortable and feel no lens at all
Dryness
Dryness (throughout the day) for stenfilcon A and etafilcon A toric lens pair is assessed. Scale 0-10, 0=extremely dried and cannot wear lens, 10=feel no dryness at all
Clarity of Vision
Clarity of vision (throughout the day) for stenfilcon A and etafilcon A toric lens pair is assessed. Scale 0-10, 0=blur vision and cannot see at all, 10=very clear with no blur vision at all
Stability of Vision
Stability of vision (throughout the day) for stenfilcon A and etafilcon A toric lens pair is assessed. Scale 0-10, 0=unstable vision and cannot see at all, 10=always stable vision
Lens Handling
Lens handling for stenfilcon A and etafilcon A toric lens pair is assessed. Scale 0-10, 0=cannot handle at all, 10=no problem at all
Overall Satisfaction
Overall satisfaction for stenfilcon A and etafilcon A toric lens pair is assessed. scale 0-10, 0=extremely un-satisfy, 10=very satisfy

5. Study Description
Brief Summary
The aim of this study is to evaluate the clinical performance of stenfilcon A toric lenses compared with etafilcon A toric lenses for astigmatism. If it is valuable, the clinical performance of stenfilcon A toric lens is also evaluated compared with habitual lenses.
Detailed Description
This is a multi-sites, 50 subjects, randomized, open labeled, bilateral wear, dispensing study. Participants will be randomized to wear first lens pair for two weeks, and then crossover to second lens pair for two weeks.
