Primary Outcome Measures :
  1. Change in axial length progression from baseline [ Time Frame: 6 months ]
    Change in axial length progression over time between DOT spectacle lenses manufactured by method A versus method B


Secondary Outcome Measures :
  1. Change in spherical equivalent refraction from baseline [ Time Frame: 6 months ]
    Changes in spherical equivalent refraction (SER) as measured by cycloplegic autorefraction over the duration of the study

Ages Eligible for Study:   6 Years to 14 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Criteria

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)
