Quest Questionnaire Classification Summary |
Subjects are classified into 1 of 4 mutually exclusive groups based on their responses to 6 individual items. 5 items were assessed using the 7-point like-rt scale. A composite score "Life Satisfaction" was calculated for each subject by summing their responses, the final score ranges 0-35 points. Where higher scores indicate higher satisfaction with life. The final item was assessed using a 5 point like-rt scale. If a subject scored 26 or higher for the composite score and responded positively (4 or 5) to the final item, then a subject was classified as "Content & Driven". If a subject scored 26 or higher but did not respond positively, then "Content & Indifferent". If a subject scored lower than 26 and responded positively, then "Discontented & Driven". Lastly, if a subject scored lower than 26 but did not respond positively, then "Discontented & Indifferent". The percentage of subjects for each group was reported. |

Proportion of Successful Lens Wearers |
Successful lens wearers were defined as subjects that fit the following criteria: 1.Completed all required study visits, 2. responded Excellent or Very Good to both the individual questionnaire items (Overall quality of vision and Overall Comfort) and 3. the investigator would recommend the study lenses. Overall quality of Vision and Overall Comfort are individual questionnaire items with the response set of 0: Not Applicable, 1: Excellent, 2: Very Good, 3: Good, 4: Fair and 5: Poor. Investigator recommendation was determined by the individual item "In your opinion, is it suitable to prescribe contact lenses for this subject? (Yes/No)". The proportion of successful lens wearers was reported. |

Monocular Contrast Threshold |
Monocular Contrast threshold was measured at Distance (4 meter) for both the left and right eyes using the M&S clinical trial suit (CTS) under standard room illumination. Contrast threshold was collected at Baseline, post lens fitting, 2-week follow-up evaluation and the 12-week evaluation. Contrast threshold at baseline was measured while wearing a spherical-cylinder refraction in a trial frame. The M&S system displayed the contrast threshold score in log units. The average contrast threshold was reported for each timepoint. |

Binocular Contrast Threshold |
Binocular Contrast threshold was measured at Distance (4 meter) using the M&S clinical trial suit (CTS) under standard room illumination. Contrast threshold was collected at Baseline, post lens fitting, 2-week follow-up evaluation and the 12-week evaluation.

Photopic Pupillometry |
Pupillometry was measured for both the left and right eyes at baseline and the 1-week follow-up evaluation . Pupil size was measured at distance, intermediate and near positions under photopic (500 lux) conditions using the NeurOptic VIP-300 pupilometer. The average pupil size across both eyes was reported for each distance and timepoint. |

Scotopic Pupillometry |
Pupillometry was measured for both the left and right eyes at baseline and the 1-week follow-up evaluation . Pupil size was measured at distance, intermediate and near positions under scotopic (0 lux) conditions using the NeurOptic VIP-300 pupilometer. The average pupil size across both eyes was reported for each distance and timepoint. |

Near Stereopsis Threshold |
Near Stereopsis threshold was collected binocularly using a Randot Stereopsis book at near (40cm) at baseline (over bare eyes), and at 10-minutes post lens fitting, 2-Week and 12-week follow-up evaluations over the study contact lenses. The average stereopsis threshold for each timepoint was reported. |

Blur Tolerance |
Blur tolerance was assessed by subjects being presented with a series on images on a screen. Two aspects of blur were evaluated, noticeable blur and objectionable blur; where, noticeable blur was defined as the threshold in diopters at which point the subject indicated a "just noticeable blur", while objectional blur was defined as the point which the subject indicated the blur of the image to be "absolutely intolerable". Blur tolerance was measured binocularly at 1-meter at baseline only. |

Fixation Disparity With Refraction |
Fixation disparity with Refraction was measured at baseline with a Mallet Unit for both distance (4 meter) and near (40 cm). This test measures small misalignments between eyes when the eyes are in a fused state. The average amount of base (prism diopters) was reported. The Amount of base can range from 0.00 to 4.00. |

Non-invasive Tear Break-up Time |
Measurement of non-invasive tear break up time (NITBUT) was conducted using a Placido disc topographer in both the left and right eyes on a bare eye at baseline and over the study contact lens 10 minutes post-lens insertion and at the 2-Week follow-up evaluation. Subjects were instructed to blink three times and then hold their eyes open. At the hold time was started, time was stopped once the first area of distortion or break in the tear film was observed. Three replicates were taken on each eye. The average NITBUT across eyes and replicate at each time point was provided. Larger values of NITBUT indicates better tear film. |

Coma |
Coma was measured over 2 seconds after blink in both the left and right eyes at baseline (over bare eye) and at 10-minutes post-lens fitting, 2-week, and 12-week follow-up evaluations over the study contact lenses using the COAS wavefront sensor. Both vertical and horizontal Coma was collected in each eye. The average vertical and horizontal coma at each timepoint was reported. |

Binocular Visual Acuity (logMAR) |
Binocular Visual Acuity (logMAR) was collected using logMAR visual acuity chart under standard room illumination at distance (4 meter), intermediate (64cm) and near (40cm) at 10 minutes-post lens fitting, and the 1-, 2-, 6- and 12-week follow-up evaluations.

Lower values of visual acuity (logMAR) indicate better vision. The average visual acuity was reported for each distance and timepoint. |
