This study is a multicenter, parallel-group, controlled, double-masked (subject and investigator), randomized clinical trial with a total duration of four years.~Part 1 of this study will study the effectiveness of MiSight 1 Day in slowing myopia progression over three years in a US population. Subjects in Part 1 will wear MiSight 1 Day lenses or Proclear 1 day lenses.~Part 2 will study the stability of the effectiveness result over a one-year post-treatment period. All subjects in Part 2 will wear Proclear 1 day lenses. Subjects and investigators will remain masked from Part 1.
The purpose of this post-approval study is to confirm the effectiveness of the MiSight 1 Day lens in clinical practices within the US and to assess the stability of the myopia reduction over one-year post-treatment.
