Outcome Measures
Primary Outcome Measures
- Visual Acuity Distance [Day 7]
High and Low Contrast LogMAR
- Subjective Vision Quality [Day 7]
Visual analogue scale (0-100 points) 100 is best possible quality of vision
- Comfort [Day 7]
Visual analogue scale(0-100 points) 100 is best possible comfort
- Visual Acuity Near [Day 7]
High and Low Contrast
- Visual Acuity Intermediate [Day 7]
High and Low Contrast
Secondary Outcome Measures
- Subjective Comfort [Day 7]
Compared to habitual lenses, rated as better/same/worse
- Subjective vision Comparison [Day 7]
Compared to habitual lenses, rated as better/same/worse
