Outcomes
Primary Outcomes
Corneal Staining by Wear Time
Time Frame: 1 hour on Day 1, 2 hours on Day 2, 4 hours on Day 3 and End of Day on Day 4
All participants were contact lenses wearers and were evaluated with a Corneal Staining at 1 hour, 2 hours, 4 hours and end of day. The corneal staining test is performed using fluorescein drops in the eye and ultraviolet illumination to determine if there has been any damage to the cornea from the use of the lens solutions or from the use of the contact lens.
Secondary Outcomes
- Subjective Solution Preference(Day 4)
- Overall Ocular Comfort(Day 4)
