3. The subject must be between 40 and 70 years of age.

4. The subject's vertex corrected spherical equivalent distance refraction must be in the range of +0.25 to +4.00 or plano to -6.00 in each eye.

8. Subject must own a wearable pair of spectacles.

9. The subject must be an adaptable soft contact lens wearer in both eyes (i.e. worn lenses a minimum of 2 days per week for at least 8 hours per day, for 1 month or more of duration)

10. The subject must already be wearing a presbyopic contact lens correction (e.g. reading spectacles over contact lenses, multifocal or monovision contact lenses, etc.) or if not responded positively to at least one symptom on the "Presbyopic Symptoms Questionnaire".

Exclusion Criteria:

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

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

3. Any systemic disease, autoimmune disease, or use of medication, which may interfere with contact lens wear.

4. Any ocular abnormality that may interfere with contact lens wear.

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

6. Any previous intraocular surgery (e.g. radial keratotomy, photorefractive keratectomy (PRK), laser-assisted in situ keratomileusis (LASIK), etc.)

7. Any grade 3 or greater slit lamp finding (e.g. edema, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival injection) which may contraindicate contact lens wear.

8. Any ocular infection or inflammation.

9. History of herpetic keratitis.

10. Any corneal distortion or irregular cornea.

11. History of binocular vision abnormality or strabismus.

12. Any infectious disease (e.g. hepatitis, tuberculosis) or contagious immunosuppressive disease (e.g. HIV).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Overall Lens Handling Using the Contact Lens User Experience(CLUE) TM Questionnaire.	CLUE Overall Lens Handling is assessed using the Contact Lens User Experience (CLUE)TM questionnaire. CLUE is a validated patient-reported outcomes questionnaire to assess patient experience attributes of soft, disposable contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Scores follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response. 97% of the scores fall within 0 and 120 (mean +/-3XSD).	15 minutes post Contact Lens Insertion
