What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Handling

    Participant's subjective rating for lens handling of Pair #1 surveyed at 2 weeks (+3) days after baseline visit and Pair #2 surveyed at 4 weeks (+3) days after baseline visit. Each pair worn for two weeks daily disposable wear basis (at least 40 hours per week). Lenses worn minimum 2 hours prior to visit. Rated by questionnaires (0-10, 10= very easy).

    Measured: two weeks and four weeks from baseline visit

  2. Satisfaction With Handling

    Participant's subjective rating for overall satisfaction of lens handling of Pair #1 surveyed at 2 weeks (+3) days after baseline visit and Pair #2 surveyed at 4 weeks (+3) days after baseline visit. Each pair worn for two weeks daily disposable wear basis (at least 40 hours per week). Lenses worn minimum 2 hours prior to visit. Rated by questionnaires (5 point Likert scale - Completely Dissatisfied, Somewhat Dissatisfied, Neither, Somewhat Satisfied, Completely Satisfied).

    Measured: two weeks and four weeks from baseline visit

Secondary outcomes (4)
  1. Comfort

    Participant's subjective rating for overall lens comfort of Pair #1 surveyed at 2 weeks (+3) days after baseline visit and Pair #2 surveyed at 4 weeks (+3) days after baseline visit. Lenses worn minimum 2 hours prior to visit. Rated by questionnaires (0-10, 10=can't feel).

    Measured: two weeks and four weeks from baseline visit

  2. Dryness

    Participant's subjective rating for overall lens dryness of Pair #1 surveyed at 2 weeks (+3) days after baseline visit and Pair #2 surveyed at 4 weeks (+3) days after baseline visit. Each pair worn for two weeks daily disposable wear basis (at least 40 hours per week). Lenses worn minimum 2 hours prior to visit. Rated by questionnaires (0-10, 10=no dryness).

    Measured: two weeks and four weeks from baseline visit

  3. Satisfaction With Dryness

    Participant's subjective rating for overall satisfaction of lens dryness of Pair #1 surveyed at 2 weeks (+3) days after baseline visit and Pair #2 surveyed at 4 weeks (+3) days after baseline visit. Each pair worn for two weeks daily disposable wear basis (at least 40 hours per week). Lenses worn minimum 2 hours prior to visit. Rated by questionnaires (5 point Likert scale - Completely Dissatisfied, Somewhat Dissatisfied, Neither, Somewhat Satisfied, Completely Satisfied).

    Measured: two weeks and four weeks from baseline visit

  4. Satisfaction With Comfort

    Participant's subjective rating for overall satisfaction of lens comfort of Pair #1 surveyed at 2 weeks (+3) days after baseline visit and Pair #2 surveyed at 4 weeks (+3) days after baseline visit. Each pair worn for two weeks daily disposable wear basis (at least 40 hours per week). Lenses worn minimum 2 hours prior to visit. Rated by questionnaires (5 point Likert scale - Completely Dissatisfied, Somewhat Dissatisfied, Neither, Somewhat Satisfied, Completely Satisfied).

    Measured: two weeks and four weeks from baseline visit
