The purpose of this study is to demonstrate that the test spectacle lens is safe and effective in slowing myopia progression in children.

Inclusion Criteria:

• Equal to or greater than 6 years and not older than 12 years at time of informed consent and assent.
• Spherical equivalent refractive error (SER) by manifest refraction between -0.75 and -4.50 D in each eye.
• Astigmatism, if present, of not more than 1.50 D.
• Difference in SER between the two eyes (Anisometropia) by manifest refraction not more than 1.00 D.
• Best corrected visual acuity in each eye equal to or better than +0.10 logMAR (≥ 20/25 as Snellen)
• Agree to wear spectacles for ≥10 hours/day at least 6 days/week.
• Willingness and ability to participate in trial for 3 years and attend scheduled visits.

Exclusion Criteria:

• History of myopia control intervention (e.g., atropine, orthokeratology, multifocal contact lenses, etc.)
• Strabismus by cover test at near or distance wearing correction.
• Amblyopia
• Any ocular or systemic condition known to affect refractive status (e.g., keratoconus, diabetes, Down's syndrome, etc.).
• Current use of ocular or systemic medications which, in the investigator's opinion, may significantly affect pupil size, accommodation or refractive state.
• Current or anticipated use of growth hormones.
• Participation in any clinical study within 30 days of the Baseline visit.
