Women who are lactating or planning a pregnancy at the time of enrollment (by verbal confirmation at the screening visit); 3. Any use of systemic or ocular medications (e.g., non-steroidal anti-inflammatory eye drops, ophthalmic steroids) within 30 days prior to study enrollment for which contact lens wear could be contraindicated, as determined by the investigator; 4. Any current or history ocular or systemic disease which may interfere with contact lens wear, as determined by the investigator; 5. Any current or previous orthokeratology treatment within 90 days prior to study enrollment, or planned for orthokeratology treatment during the study; 6. Any previous history of ocular and/or refractive surgery (e.g., radial keratotomy, PRK, LASIK, etc.) or planned for ocular and/or refractive surgery during the study; 7. Current or history of herpetic keratitis in either eye; 8. Current or history of intolerance, hypersensitivity or allergy to silicone hydrogel soft contact lenses or any component of the study products; 9.

Any biomicroscopy findings at screening that are Grade 3 or higher and/or corneal neovascularization that is Grade 2 or higher and/or presence of corneal infiltrates; 13. Any history of a contact lens-related corneal inflammatory or infectious event within 12 months prior to study enrollment that may contraindicate contact lens wear; 14.
