  • Cycloplegic SER from -0.25 (non-inclusive) to +0.75 D (inclusive) in both eyes.
  • Astigmatism ≤ -1.00D in both eyes.
  • Un-corrected visual acuity (UCVA) ≤ 0.1 LogMAR.
  • As applicable (dependent on local requirements), the subject and parent/legal guardian will have read the Informed Assent/Consent, been given an explanation of the study, indicated an understanding and signed the forms.
  • Along with their parent or guardian, be capable of comprehending the nature of the study, and be willing and able to adhere to the instructions set forth in this protocol.

  • Be in good general health, based on his/her and parent's/guardian's knowledge.
  • Any history of myopia control interventions with in 1 month must complete a 4-weeks of washout period.

You may not qualify if:

  • History of myopia control intervention (e.g., atropine, orthokeratology, soft myopia control contact lenses, red light therapy, etc. over more than 1 month)
  • Currently wears rigid gas permeable contact lenses, including orthokeratology lenses.
  • Current use of systemic or ocular or medications which may affect contact lens wear, tear film production, pupil size, accommodation or refractive state.
  • Ocular or systemic disease that contraindicates contact lens wear.
  • Active allergic conjunctivitis.
  • Any ocular, systemic or neuro-developmental conditions that could influence refractive development.
  • Keratoconus or an irregular cornea.
  • History of clinically significant binocular vision abnormality or strabismus.
  • Any active anterior segment finding that would contraindicate contact lens wear.
  • The investigator for any reason considers that it is not in the best interest of the subject to participate in the study.
