10. The subject must have a spherocylindrical best corrected distance Snellen visual acuity of 20/25+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:

1. Currently pregnant or lactating (subjects who become pregnant during the study will be discontinued).

2. Any active or ongoing systemic disease (e.g., Sjögren's Syndrome), infectious disease (e.g., hepatitis, tuberculosis), contagious immunosuppressive diseases (e.g., HIV), autoimmune disease (e.g. rheumatoid arthritis).

3. Subjects taking suspect oral medications for less than one year.

4. Any prescribed or over the counter (OTC) ocular medication.

5. Any known hypersensitivity or allergic reaction to Optifree® PureMoist® multi-purpose care solution or Eye-Cept® rewetting drop solution.

6. Toric, extended wear, monovision or multi-focal contact lens correction.

7. Any previous or planned (during the course of the study) ocular surgery (e.g., PRK, LASIK, etc.).

8. Participation in any contact lens or lens care product clinical trial within 30 days prior to study enrollment.

9. Participation in clinical trials involving the Test lens within 3 months prior to study enrollment.

10. Employee or immediate family member of an employee of clinical site (e.g., Investigator, Coordinator, Technician).

11. Binocular vision abnormality or strabismus by self-report or prior medical history.

12. History of recurrent corneal erosions, herpetic keratitis, or pathological dry eye.

13. Any active ocular allergies, infections or other ocular abnormalities (entropion, ectropion, extrusions, chalazia, recurrent styes, glaucoma) that the investigator determines may interfere with the outcomes of this study or otherwise contraindicate participation in the study.

14. Any Grade 2 or greater slit lamp findings (e.g., edema, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival injection) on the FDA Slit Lamp Classification Scale.

15. Any previous history or signs of a contact lens-related corneal inflammatory event (e.g., past peripheral ulcer or round peripheral scar) within the past 3 years of otherwise successful contact lens wear.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Overall Comfort Score	Overall comfort was assessed using the Contact Lens User Experience™ (CLUE) questionnaire. CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patientexperience 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.	2-Week Follow-up Evlauation
Primary	Vision Satisfaction in Bright Lighting	Vision satisfaction in bright light was assessed using the individual item" I was satisfied with the quality of my vision in bright lighting" from the CLUE™ questionnaire. This item used the response scale, 1: Strongly Disagree, 2: Disagree, 3: Neither Agree nor Disagree, 4: Agree and 5: Strongly Agree. CLUE is the Contact Lens User Experience™ 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 Proportion of responses in each category were reported for each lens type.	2-Week Follow-up Evaluation
Primary	Distance Visual Acuity	Distance visual acuity was assessed by eye using LogMAR visual acuity at 4 meters using an ETDRS chart under high illumination high contrast conditions (room illumination > 400 lux and chart luminance 120-200 cd/m2) at the 2-week follow-up for each subject eye. Lower values of logMAR indicate better vision, where a score of 0.0 equates to 20/20 snellen vision. The average visual acuity for each lens was reported.	2-Week Follow-up Evlauation
Primary	Contact Lens Fitting Acceptance Rate	Acceptable lens fit will be assessed at all study visits (scheduled and unscheduled) for each subject eye. Fit acceptance rate will be based on the lens fit acceptance of eyes wearing the Test lens only. Fit acceptance is a binary response where Y=1 if lens fit is acceptable and Y=0 otherwise. Unacceptable is defined as unacceptable if any one of the following criteria: limbal exposure at primary gaze or with extreme eye movement; edge lift; excessive movement in primary up gaze; insufficient movement in all three of the following conditions: primary gaze, up gaze, and push up test.; Eyes with multiple unacceptable fitting events will be counted only once. Fit rates of the Control lens will also be collected but are not a primary endpoint.	Up to 2-Week Follow-up
Primary	Number of Grade 3 or Higher Slit Lamp Findings	Slit Lamp Findings (SLF) were assessed using a biomicroscope and was graded using the FDA grading scale (Grade: 0, 1,2, 3 and 4) with grade 0 represents the absence of findings and 1 to 4 representing successively worse findings (i.e. Grade 1 = trace, Grade 2 = Mild, Grade 3 = moderate and Grade 4 = severe). Slit Lamp Findings will be assessed for each subject eye at all study visits (schedule and unscheduled). SLF is a binary response where Y=1 for at least one Grade 3 or 4 slit lamp finding. The percentage of eyes with Grade 3 or higher slit lamp findings will be analyzed and will include corneal infiltrates. Eyes with multiple events will be counted only once. The number of eyes with SLF with grade 3 or higher by lens was reported.	Up to 2-Week Follow-up Evlauation
Secondary	Overall Handling Score	Overall handling was assessed using the Contact Lens User Experience™ (CLUE) questionnaire. CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patientexperience 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.	2-Week Follow-up Evlauation
Secondary	Overall Quality of Vision Score	Overall quality of vision was assessed using the Contact Lens User Experience™ (CLUE) questionnaire. CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patientexperience 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.	2-Week Follow-up Evlauation
