| Visual Performance (logMAR) | Binocular visual performance on logMAR (Logarithm of Minimal Angle of Resolution) scale was evaluated at distance (4 m), intermediate (64 cm) and near (40 cm) under high luminance high contrast lighting conditions using ETDRS (Early Treatment Diabetic Retinopathy Study) charts. The room illuminance was required to be between 7.3 and 7.9 EV (394-597 lux). For Distance (4 m), the acceptable range for the chart luminance was 10.5-10.7 EV (181-208 cd/m2). For Intermediate (64cm) and Near (40cm), the cceptable range for the chart luminance 10.8-11.1 EV (223-274 cd/m2). Letter-by-letter results calculated the visual performance score for each chart read. logMAR scores closer to zero, or below zero, indicate a better visual acuity. A logMAR visual performance score of 0.0 is equivalent to Snellen visual acuity of 20/20. The average score was reported for each lens. | 1-Week Follow-up |
| Measure | Description | Time Frame |
|---|---|---|
| CLUE Vision | Subjective vision was assessed using the Contact Lens User Experience™ (CLUE) questionnaire. CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response with a range of 0-120. The average CLUE vision score for each lens type was reported. |

Inclusion Criteria:
Potential subjects must satisfy all the following criteria to be enrolled in the study:
The subject must read, understand, and sign the STATEMENT OF INFORMED CONSENT and receive a fully executed copy of the form.
The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.
The subject must be at least 40 years of age and not greater than 70 years of age at the time of consent.
Subjects must own a wearable pair of spectacles if required for their distance vision.
The subject must be an adapted soft contact lens wearer in both eyes (i.e. worn lenses a minimum of 2 days per week for at least 6 hours per wear day, for 1 month or more duration).
The subject must either already be wearing a presbyopic contact lens correction (e.g., reading spectacles over contact lenses, multifocal or monovision contact lenses, etc.) or, if not respond positively to at least one symptom on the "Presbyopic Symptoms Questionnaire" (Appendix E).
The subject's distance spherical equivalent refraction must be in the range of +1.25 D to +3.75 D in each eye.
The subject's refractive cylinder must be ≤0.75 D in each eye.
The subject's ADD power must be in the range of +0.75 D to +2.50 D.
The subject must have distance best corrected visual acuity of 20/20-3 or better in each eye.
Exclusion Criteria:
Potential subjects who meet any of the following criteria will be excluded from participating in the study:
