Time Frame: Up to Day 28
Overall comfort, as rated by the participant on a 10-point scale, with 1 being poor and 10 being excellent. The participant rated both eyes together by providing one single rating.
Secondary Outcomes
- Subjective Rating of Overall Vision(Up to Day 28)
- Proportion of Subjects Preferring Study Lens (Strongly or Somewhat)(Day 28)
