Inclusion criteria

• Volunteer participant with the willingness and ability to comply with all scheduled study visits.
• Informed consent of parent/guardian and assent of participant.
• Age equal to or greater than 6 years and less than 11 years (before 11th birthday) at the time of consent.
• Spherical equivalent refraction (SER) equal or less than -0.50 D and equal or greater than -4.75D with astigmatism not more than 2.00 D.
• Difference in SER (anisometropia) between two eyes should not exceed 1.00 D.
• Best corrected Distance Visual Acuity (BCDVA) better than or equal to +0.10 LogMAR under high contrast in each eye.
• Be in good general health, based on the participant and the parent's/guardian's knowledge.
• Agree to wear the study spectacles for 12 hours per day and 7 days per week.
• Agree not to be involved in other myopia control treatments.

Exclusion criteria

• History of Atropine, Orthokeratology, Myopia Control Contact Lens, or Red Light treatment.
• Strabismus by cover test at near or distance wearing correction.
• History and presence of amblyopia.
• Any ocular or systemic condition known to affect refractive status (e.g. keratoconus, diabetes, Downs syndrome, or other developmental disorders, etc.).
• Current use of ocular or systemic medications which, in the investigator's opinion, may significantly affect pupil size, accommodation or refractive state.
• History of ocular injury or surgery.
• Participation in any clinical study within 30 days of the Baseline visit.
• Current or anticipated use of growth hormones.
• Study participants deemed inappropriate for the study by the investigator.
• The inherent ocular/systemic discomfort (dry eyes, visual fatigue, headaches, etc.) that may affect the evaluation of the study lens wearing experience, from the investigator's perspective.
