The Purpose of this study is to explore the safety and effectiveness of SAT-001, a medical device for the treatment of myopia in pediatric patient with myopia

Myopic pediatric prevalence rate come to increase rapidly globally. This is a clinical trial to explore the safety and effectiveness of SAT-001(as a Software as Medical Device) developed for the treatment of myopia through suppressing the progress myopia

   3. Anisometropia of less than 1.00 D

3. The age of birth over 38 weeks

4. Over 2500g of birth weight

2. Current or previous use of multi-focal lenses
3. Planning to use or having used Orthokeratology lenses (Ortho-K lenses), Rigid Gas Permeable (RGP) lenses, and other contact lenses to reduce the progression of myopia
