- •Subjects must have acceptable near vision (without vision correction) and be able to see the test article lenses in the mirror 30 cm or closer.
- •Subjects must have best corrected visual acuity of 20/40 (Snellen or equivalent) or better in each eye.
- •Subjects must possess a functional/usable pair of spectacles and bring them to the visit (only if applicable-to the investigators 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 this clinical protocol
排除标准
- •Subjects, or subjects' family member within the same household, that work for the following entities/companies: Government, advertising, marketing research or consultancy, media or public relations, companies that make, distribute or sell eyewear or contact lenses, eyecare practice (optometrist, ophthalmologist, optician) or the research center conducting the study
- •Habitual wearers of rigid gas permeable lenses within the last 3 months
- •Habitual soft conventional contact lens wearers (conventional lenses defined as replacement modality of greater than 1 month)
- •Any color deficiencies, by self report
- •Currently pregnant or breast-feeding a baby
- •Any ocular or systemic allergies or diseases which may interfere with contact lens wear
- •Any systemic disease, autoimmune disease, or use of medication which may interfere with contact lens wear, at the investigator's discretion
- •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 may interfere with contact lens wear (this includes, but not limited to, chalazia, recurrent styes, pterygium, infection, etc.)
- •Any corneal distortion or moderate or above corneal distortion by self report
- •History of any corneal refractive surgery
- •Habitual contact lens is multifocal, monovision or worn as extended wear

结局指标
主要结局
Number of Subject in Agreement (Bigger Eyes)
时间窗: 15-20 Minutes Post Lens Insertion
Subjects' responses to the question "Make my eye look bigger" were categorized into a binary variable. If a subject responded "Agrees Somewhat" or "Agrees Strongly" then response=1. If a subject responds "Neither Agrees nor Disagrees", "Disagrees Somewhat" "Disagrees Strongly" then response=0. The number of subjects with response=1 was reported for each lens.
Number of Subject in Agreement (Defines Eyes)
时间窗: 15-20 Minutes Post Lens Insertion
Subjects' responses to the question "Define my eye" were categorized into a binary variable. If a subject responded "Agrees Somewhat" or "Agrees Strongly" then response=1. If a subject responds "Neither Agrees nor Disagrees", "Disagrees Somewhat" "Disagrees Strongly" then response=0. The number of subjects with response=1 was reported for each lens.
Number of Subject in Agreement (Enhance Eyes)
时间窗: 15-20 Minutes Post Lens Insertion
Subjects' responses to the question "Enhance my overall appearance" were categorized into a binary variable. If a subject responded "Agrees Somewhat" or "Agrees Strongly" then response=1. If a subject responds "Neither Agrees nor Disagrees", "Disagrees Somewhat" "Disagrees Strongly" then response=0. The number of subjects with response=1 was reported for each lens.
