This is a pilot evaluation to assess the feasibility of using novel imaging process to characterize lens edge and limbal epithelial thickness profile; lens movement with gaze and blink; and conjunctival microvasculature including fractal analysis of microvascular perfusion maps and blood flow velocity.

This is a pilot evaluation to assess the feasibility of using ultra-high resolution optical coherence tomography (OCT) to image and characterize lens edge and limbal epithelial thickness profile; lens movement with gaze and blink; and conjunctival microvasculature including fractal analysis of microvascular perfusion maps and blood flow velocity.

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 at least 18 and not more than 70 years of age.

• The subject must have best corrected visual acuity of 20/25 or better in each eye.
• The subject must be either a neophyte or a habitual and adapted wearer of soft contact lenses in both eyes.
• The subject must have normal eyes (i.e., no ocular medications or infections of any type).
• The subject must demonstrate adequate mobility and 20/30 vision oculus dexter (OD) and oculus sinister (OS) with the study contact lenses.

Exclusion Criteria:

• Any previous, or planned, ocular or interocular surgery (e.g., radial keratotomy, photorefractive keratectomy (PRK), laser-assisted in-situ keratomileusis (LASIK), etc.).
• Any grade 3 or greater slit lamp findings (e.g., edema, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival injection) on the FDA classification scale, any previous history or signs of a contact lens-related corneal inflammatory event (e.g., past peripheral ulcer or round peripheral scar), or any other ocular abnormality that may contraindicate contact lens wear.
• Any ocular infection.
• Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.
• Monovision or multi-focal contact lens correction.
• Participation in any contact lens or lens care product clinical trial within 14 days prior to study enrollment.
