Inclusion Criteria

• Participants must satisfy the following conditions for inclusion in the trial:

  • Be between 9 and 30 years of age
  • Sign written Informed Consent/Assent.
  • Spherical Equivalent glasses prescription: -0.50 to -7.00 diopters (D), Astigmatism: ≤ -0.75D, Anisometropia: ≤ 1.00D

  • Be willing and able to follow instructions and attend the schedule of follow-up visits.

Exclusion Criteria

• Any of the following will exclude a participant from this trial:

  • Current hard lens wearers
  • Using eye medication contraindicating lens wear such as daily use of artificial tears.
  • Eye injury or surgery within twelve weeks immediately prior to enrollment for this trial.
  • History of corneal refractive surgery
  • Currently enrolled in an ophthalmic clinical trial that could negatively impact corneal or conjunctival health in this trial.
  • Evidence of systemic or ocular abnormality, infection or disease likely to affect successful wear of contact lenses or use of their accessory solutions.
  • Allergy or sensitivity to any product used in this trial.
  • Pre-existing ocular condition that would contraindicate lens wear.
  • Any systemic disease including autoimmune disease, immunocompromising diseases, connective tissue disease, clinically significant atopic diseases, insulin dependent diabetes, use of medications including corticosteroids and antimetabolites that may affect the eye or be exaggerated by wearing contact lenses.
  • Lazy eye (Strabismus or amblyopia)
