Conditions
Brief summary
This study will compare the effects on myopia progression over the course of one year for eyes wearing MiSight 1 Day contact lenses compared to ACUVUE OASYS for PRESBYOPIA contact lenses.
Interventions
ACUVUE OASYS for PRESBYOPIA contact lenses prescribed by a registered optometrist to children with myopia will be worn in one eye for 10 hours a day for one year. These lenses will be provided to participants by the study. The lens power will be determined at the discretion of the optometrist. These lenses will be in different packaging than lenses for the other eye.
