Description
Inclusion Criteria:
- 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 between 35 and 42 years of age (inclusive).
- The subject's vertex corrected spherical equivalent distance refraction must be in the range of -6.00 Diopters (D) to +4.00 D in each eye.
- The subject's refractive cylinder must be ≤ 0.75 D in each eye.
- The subject must have best corrected visual acuity of 20/30 or better in each eye.
- The subject must be an adapted soft contact lens wearer in both eyes (defined as a minimum of 6 hours of Daily Wear (DW) for a minimum of 1 month prior to the study).
- The subject must have normal eyes (i.e., no ocular medications or infections of any type).
Exclusion Criteria:
- Currently pregnant or lactating (subjects who become pregnant during the study will be discontinued).
- Any ocular or systemic allergies or diseases that may interfere with contact lens wear.
- Any infectious disease (e.g., hepatitis, tuberculosis) or a contagious immunosuppressive disease (e.g., HIV) by self-report.
- Clinically significant (grade 3 or 4) corneal edema, corneal vascularization, corneal staining, or any other abnormalities of the cornea which would contraindicate contact lens wear.
- Clinically significant (grade 3 or 4) tarsal abnormalities or bulbar injection which might interfere with contact lens wear.
- Any ocular infection.
- Any previous, or planned, ocular or interocular surgery (e.g., radial keratotomy, photorefractive keratectomy (PRK), laser-assisted in situ keratomileusis (LASIK), etc.)
- Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.
- Habitual contact lens type is toric, bifocal, in monovision contact lens wear, or is worn as extended wear.
- Participation in any contact lens or lens care product clinical trial within 30 days prior to study enrollment.
- Employee of investigational clinic (e.g., Investigator, Coordinator, Technician)

Measure Description |
Time Frame |
|---|---|---|
|
The Binocular Functional Visual Performance Under Distance Day Time Conditions (250 cd/m2) for Centrally Presented High Contrasts (HC) Time Controlled Visual Acuity (TCVA) Targets.
Time Frame: 15 minutes post lens fit
|
Time Controlled Visual Acuity (TCVA) was assessed at 4 m using 250 cd/m2 luminance. The luminance requirements were same at the target and at the eye. Binocular functional visual performance was measured for the centrally presented high contrasts targets. |

The Binocular Functional Visual Performance Under Distance Night Time Conditions (2.5 cd/m2) for Centrally Presented HC TCVA Targets.
Time Frame: 15 Minutes post lens fitting
|
Time Controlled Visual Acuity (TCVA) was assessed at 4 m using 2.5 cd/m2 luminance.
The luminance requirements were same at the target and at the eye.
Binocular functional visual performance was measured for the centrally presented high contrasts targets.

The Binocular Functional Visual Performance Under Intermediate Vision Indoor Conditions (50 cd/m2) for Centrally Presented HC TCVA Targets.
Time Frame: 15 Minutes post lens fitting
|
Time Controlled Visual Acuity (TCVA) was assessed at 67 cm using 50 cd/m2 luminance.
The luminance requirements were same at the target and at the eye.
Binocular functional visual performance was measured for the centrally presented high contrasts targets.
