Criteria

Inclusion Criteria:

  • Be between 8 and 12 years of age inclusive.
  • Best-corrected visual acuity by manifest refraction of +0.10 logMAR.
  • Spherical Equivalent Refractive Error between -0.75 and -4.00 D inclusive astigmatism: < -0.75 D anisometropia: < 1.00 D
  • Possess wearable and visually functional eyeglasses.
  • Agree to wear the assigned contact lenses for a minimum of 10 hours per day, - at least 6 days per week, for the duration of the 3 year study.

Exclusion Criteria:

  • Subject has previously or currently wears contact lenses or rigid gas permeable contact lenses, including orthokeratology lenses.
  • Subject is currently or within 30 days prior to this study has been an active participant in another clinical study.
  • Current or prior use of bifocals, progressive addition lenses, atropine, pirenzepine or ANY other myopia control treatment.
  • Regular use of ocular medications (prescription or over-the-counter), artificial tears, or wetting agents.
  • Current use of systemic medications which may significantly affect contact lens wear, tear film production, pupil size, accommodation or refractive state.
  • A known allergy to fluorescein, benoxinate, proparacaine or tropicamide.
  • Strabismus by cover test at far (4 m) or near (40 cm) wearing distance correction.
  • Any ocular, systemic or neuro-developmental conditions that could influence refractive development.
