Who can join

Age: 18 and older, up to 39. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Potential subjects must satisfy all the following criteria to be enrolled in the study.
• The subject must:
• Read, understand, and sign the STATEMENT OF INFORMED CONSENT and receive a fully executed copy of the form.
• Appear able and willing to adhere to the instructions set forth in this clinical protocol.
• Be between 18 and 39 (inclusive) years of age at the time of screening.
• By self-report, habitually wear soft contact lenses in both eyes in a daily reusable or daily disposable wear modality (i.e., not extended wear modality). Habitual wear is defined as a minimum of 6 hours of wear per day, for a minimum of 2 days per week during the past month.
• Possess a wearable pair of spectacles that provide correction for distance vision.
• Have the spherical component of their vertex-corrected distance refraction must be between -0.875 to -4.625 DS (inclusive) in each eye.
• Have the magnitude of the cylindrical component of their vertex-corrected distance refraction between 0.625 DC and 1.625 DC in both eyes.
• Have the cylinder axis of their distance refraction between 165° and 15° (i.e., 180±15°, inclusive) or between 75° and 105° (i.e., 90±15°, inclusive) in each eye.
• Have best corrected monocular distance visual acuity of 20/30 or better in each eye.

You may not qualify if…

• Potential subjects who meet any of the following criteria will be excluded from participating in the study.
• The subject must not:
• Be currently pregnant or lactating.
• Be diabetic.
• Be currently using any ocular medications or have any ocular infection of any type.
• By self-report, have any ocular or systemic disease, allergies, infection, or use of medication that might contraindicate or interfere with contact lens wear, or otherwise compromise study endpoints, including infectious disease (e.g., hepatitis, tuberculosis), contagious immunosuppressive disease (e.g., Human Immunodeficiency Virus [HIV]), autoimmune disease (e.g., rheumatoid arthritis, Sjögren's syndrome), or history of serious mental illness or seizures. See section 9.1 for additional details regarding excluded systemic medications.
• Have habitually worn rigid gas permeable (RGP) lenses, orthokeratology lenses, or hybrid lenses (e.g., SynergEyes, SoftPerm) within the past 6 months.
• Be currently wearing monovision or multifocal contact lenses.
• Be currently wearing lenses in an extended wear modality.
• Have a history of strabismus or amblyopia.
• Be an employee (e.g., Investigator, Coordinator, Technician) or immediate family member of an employee (including partner, child, parent, grandparent, grandchild or sibling of the employee or their spouse) of the clinical site.
• Have participated in a contact lens or lens care product clinical trial within 7 days prior to study enrollment.
• Have clinically significant (grade 3 or higher on the FDA grading scale) slit lamp findings (e.g., corneal edema, neovascularization or staining, tarsal abnormalities or bulbar injection) or other corneal or ocular disease or abnormalities that contraindicate contact lens wear or may otherwise compromise study endpoints (including entropion, ectropion, chalazia, recurrent styes, glaucoma, history of recurrent corneal erosions, aphakia, moderate or above corneal distortion, herpetic keratitis).
• Have fluctuations in vision due to clinically significant dry eye or other ocular conditions.
• Have had or have planned (within the study period) any ocular or intraocular surgery (e.g., radial keratotomy, PRK, LASIK, iridotomy, retinal laser photocoagulation, etc.).
