Randomized, controlled, multisite, subject- and observer-masked, contralateral clinical trial of 6-month duration to compare two SightGlass Vision Diffusion Optics Technology (DOT) spectacle lens manufacturing processes in reducing the progression of juvenile myopia.

Inclusion Criteria:

• Children between the ages of 6 and 14 years old (inclusive) with myopia
• Best corrected visual acuity by manifest refraction of +0.10 logMAR (20/25 Snellen equivalent) or better in each eye
• Difference in spherical equivalent power between the two eyes (anisometropia based on manifest refraction) must be less than or equal to 0.75 D

Exclusion Criteria:

• Current use of any myopia control treatment such as atropine, multifocal contact lenses, or orthokeratology (NOTE: Prior bilateral usage acceptable as long as treatment stopped at least 6 months before screening visit. Any subject with a history of unilateral myopia control treatment is excluded.)
• Any ocular or systemic conditions that could influence refractive development or status [e.g., keratoconus, congenital glaucoma, ocular trauma, diabetes, Marfan syndrome or other connective tissue disorder, Down's syndrome, family history of poor night vision (to prevent against enrolling subjects with congenital stationary night blindness)](streamdown:incomplete-link)

This was a contralateral eye study of 50 participants in which both eyes were enrolled. In the analysis set, each group has 43 eyes with a total of 43 participants.
