Eligibility Criteria
Inclusion Criteria
- Subjects must be at least 18 years of age and no more than 55 years of age (inclusive).
- The subject's vertex corrected best spherical distance refraction must be in the range of -1.00 to -6.00 Diopters (D) in each eye.
- The subject's vertex corrected cylindrical component of distance refraction must be less than or equal to -1.50 Diopters of Cylinder (DC) in each eye.
- Subjects must have best corrected visual acuity of 20/25 (Snellen or equivalent) or better in each eye.
- Subjects must self-report as being Asian race.
- Subjects must self-report as having brown or black eyes.
- Subjects must be habitual lens wearer (clear or limbal ring cosmetic) . Habitual is defined as at least one (1) month of Contact Lens wear where the lenses were worn for a minimum of six (6) hours per day and a minimum of three (3) days per week.
- Subjects between 18 to 39 years old must be habitual limbal ring cosmetic lens wearers or must have tried limbal ring cosmetic lens within the past two years.
- Subjects must be cosmetic contact lens concept acceptors as determined by screening questionnaire.
- Subjects must possess a functional / usable pair of spectacles and bring them to the visit (only if applicable - to the investigator's discretion).
- Subjects must read, understand, and sign the Statement of Informed Consent.
- Subjects must appear able and willing to adhere to the instructions set forth in the clinical protocol.
- Subjects must be willing to have their eyes video recorded and photographed.

- Pregnant or breast feeding a baby.
- Subjects with diabetes.
- Any ocular or systemic allergies or disease which might interfere with contact lens wear.
- Any systemic disease, or autoimmune disease, which might interfere with contact lens wear, at investigator's discretion.
- Using medications during and immediately preceding the study period that may interfere with current contact lens wear as determined by the investigators
- Any infectious diseases (e.g. hepatitis, tuberculosis) or a contagious immunosuppressive disease (e.g. HIV), by self-report.
- Any grade 3 or greater Biomicroscopy findings (this includes, corneal edema, corneal staining, corneal vascularization, conjunctival injection, tarsal abnormalities, bulbar injection) on the FDA classification scale.
- Any active ocular abnormalities/conditions that might interfere with contact lens wear (this includes, but not limited to, chalazia, recurrent styles, pterygium, infection etc.).
- Any corneal distortion, scar, or opacity affecting vision as noted by subjects or investigators during examination.
- History of any corneal surgery (e.g. radial keratotomy (RK), photorefractive keratectomy (PRK), laser-assisted in situ keratomileusis (LASIK)); confirmed with topography if necessary at the investigator's discretion.
- Habitual wearers of rigid gas permeable or orthokeratology lens within the past 3 months.
- Current habitual contact lens modality for extended wear or conventional wear (contact lenses with a replacement schedule of 3 months to >1 year).
- Participation in any pharmaceutical, medical device, or contact lens related clinical research trial within 14 days prior to study enrollment. This excludes studies that do not require product treatment/intervention.
