Eligibility Criteria
Inclusion
- Has had an oculo-visual examination in the last two years.
- Is at least 18 years old and has full legal capacity to volunteer or is at least 16 years old, has a parent or guardian's permission to participate in the study and has read the Information and Consent Letter for adolescents.

- 6\. Has a refractive error that is correctable with the prescription of the available study lenses.
- 7\. Has a refractive error that is correctable to at least 20/25 distance visual acuity with contact lenses in each eye.
- 8\. Has acceptable fit with the study lenses. 9. Has clear corneas, and ocular clinical findings are considered "normal".
Exclusion
- Has any systemic disease that may affect ocular health.
- Is using any systemic or topical medications that may affect ocular health.
- Has any ocular pathology or severe insufficiency of lacrimal secretion (dry eyes) that may affect the wearing of contact lenses.
- Has any clinically significant lid or conjunctival abnormalities, meibomian gland dysfunction, neovascularization, corneal scars or corneal opacities.
- Has limbal injection, bulbar injection or corneal staining that, in the investigator's opinion, is clinically significant.
- Has pinguecula and/or pterygium that, in the investigator's judgement, makes contact lens wear inadvisable.
- Has refractive astigmatism of more than 0.75 D.
- Has corneal distortion resulting from rigid lens wear.
- Is aphakic.
- Has undergone corneal refractive surgery.
- Is participating in any other type of clinical or research study.
