Outcome Measures
Primary Outcomes (1)
Change in Axial Length Progression From Baseline
Change in axial length progression over time between DOT spectacle lenses manufactured by method A versus method B Axial length progression is defined as an axial length elongation that is attributable to myopia.
6 months
Study Arms (2)
DOT Spectacle Lenses using Manufacturing Method A
EXPERIMENTALSingle vision, impact-resistant spectacles using SightGlass Vision DOT spectacle lenses, manufacturing method A
DOT Spectacle Lenses using Manufacturing Method B
EXPERIMENTALSingle vision, impact-resistant spectacles using SightGlass Vision DOT spectacle lenses, manufacturing method B
Interventions
Subjects randomized to test vs control, left eyes and right eyes
Eligibility Criteria
You may qualify if:
- 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
You may not qualify if:
- 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)
