Eligibility Criteria

Age6 Years - 14 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

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)
