Eligibility

Inclusion Criteria:

• Potential subjects must satisfy all of the following criteria to be enrolled in the study.

1. The subject must read, understand, and sign the STATEMENT OF INFORMED CONSENT and receive a fully executed copy of the form.

2. The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.

3. The subject must be at least 40 years of age and not greater than 70 years of age at the time of consent.

4. Subjects must own a wearable pair of spectacles if required for their distance vision.

5. 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).

6. 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".

7. The subject's distance spherical equivalent refraction must be in the range of -1.25 D to -3.75 D in each eye.

8. The subject's refractive cylinder must be =0.75 D in each eye.

9. The subject's ADD power must be in the range of +0.75 D to +2.50 D.

10. 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:

1. Currently pregnant or lactating.

2. Any active or ongoing ocular or systemic allergies that may interfere with contact lens wear.

3. Any active or ongoing systemic disease, autoimmune disease, or use of medication, which may interfere with contact lens wear. This may include, but not be limited to, diabetes, hyperthyroidism, Sjögren's syndrome, xerophthalmia, acne rosacea, Stevens-Johnson syndrome, and immunosuppressive diseases or any infectious diseases (e.g. hepatitis, tuberculosis).

4. Any previous, or planned, ocular or intraocular surgery (e.g. radial keratotomy, PRK, LASIK, lid procedures, cataract surgery, retinal surgery, etc.).

5. A history of amblyopia, strabismus or binocular vision abnormality.

6. Use of any of the following oral medications within 2 weeks prior to enrollment:

oral retinoids, oral tetracyclines, anticholinergics, systemic/topical steroids. See section 9.1 for additional details regarding excluded systemic medications.

7. Use of any ocular medication, with the exception of rewetting drops.

8. History of herpetic keratitis.

9. History of irregular cornea.

10. History of pathological dry eye.

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

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

13. Any known hypersensitivity or allergic reaction to non-preserved rewetting drop solutions or sodium fluorescein.

14. Clinically significant (Grade 2 or greater) corneal edema, corneal vascularization, corneal staining, tarsal abnormalities or bulbar injection, or any other corneal or ocular abnormalities which would contraindicate contact lens wear.

15. Entropion, ectropion, extrusions, chalazia, recurrent styes, dry eye, glaucoma, history of recurrent corneal erosions.

16. Any current ocular infection or inflammation.

17. Any current ocular abnormality that may interfere with contact lens wear.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Subjective Vision Scores	Subjective 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 patient- xperience 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.	1-Week Follow-up
Primary	Visual Acuity (logMAR)	High contrast bright illumination binocular logMAR (Logarithm of the Minimum Angle of Resolution) visual acuity was assessed at distance (4 meters) using ETDRS Charts, near (40 cm) and intermediate (64 cm) using reduced Guillon-Poling charts. A value of 0.0 logMAR indicated a Snellen vision of 20/20. Lower logMAR visual acuity values indicates better vision. The average logMAR visual acuity for each lens was reported. Note: The room illuminance was required to be between 7.3 and 7.9 EV (394-597 lux). Acceptable Luminance Range for Distance (4M): 10.5-10.7 EV (181-208 cd/m2). Acceptable Luminance Range for Near (40cm) and Intermediate Guillon-Poling :10.8- 11.1 EV (223-274 cd/m2).	1-Week Follow-up
