Outcome Measures
Primary Outcomes (1)
Subjective At-home Ratings for Ease of Lens Handling for Insertion
Subjective at-home ratings for ease of Lens handling for insertion will be assessed using a 0-10 scale, (0=very difficult, 10=very easy)
Day 13

Lens B (Control)
ACTIVE COMPARATORSubjects will be randomized to wear Lens B (control) and Lens A (Test) for 2 weeks in this randomized, cross-over bilateral dispensing study.
Habitual Lenses
ACTIVE COMPARATORAll subjects will wear their habitual lenses for two weeks prior to randomization of Test lens A and control lens B.
Interventions
Subjects will be randomized to wear Lens A (test) for 2 weeks.
Subjects will be randomized to wear Lens B (control) for 2 weeks.
