Eligibility Criteria

All participants from 8 years up to 12 years old.

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.
