Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Spherical equivalent refractive error between -0.75 and -4.50 D inclusive (by manifest refraction) in each eye;
3. Astigmatism if present, less than or equal to -1.25 DC (by manifest refraction) in each eye;
4. Best corrected visual acuity by manifest refraction of +0.10 logMAR (20/25 Snellen equivalent) or better in each eye;
5. The difference in spherical equivalent power between the two eyes (anisometropia based on manifest refraction) must be less than or equal to 1.50 D;
6. Agree to wear the assigned spectacles constantly except for sleeping, swimming, or other activities in which spectacle wear would be dangerous or otherwise not possible (minimum of 10 hours per day);
7. Ability to comply with study procedures, including high and low contrast visual acuity, axial length, and cycloplegic autorefraction measurements taken for both eyes at the baseline visit;
8. Willingness to participate in the trial for 24 months without contact lens wear;
9. The subject's parent(s) or legal guardian(s) must read, understand and sign the Statement of Informed Consent and receive a fully executed copy of the form.
Exclusion Criteria
2. Current or prior use of bifocals, progressive addition spectacle lenses
3. Current or prior use of any myopia control treatment (e.g., atropine, multifocal contact lenses, orthokeratology);
4. Amblyopia in either eye;
5. Strabismus by cover test at far (4 m) or near (40 cm) wearing distance correction;
6. Any ocular or systemic conditions that could influence refractive development or status \[e.g., keratoconus, congenital glaucoma, ocular trauma, diabetes, Marfan syndrome or other connective tissue disorder, Down's syndrome, family history of poor night vision (to prevent against enrolling subjects with congenital stationary night blindness)\];
7. Known allergy to proparacaine, tetracaine, or tropicamide;
8. Participation in any investigational clinical study within 30 days of the Baseline visit;
9. Subject's sibling or other household member is already enrolled in this trial.
