Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study is to evaluate the efficacy of these three methods in controlling myopia progression. Until now, there is no sufficient clinical evidences to compare different lens treatments.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Spectacles
Spectacles are the most common lens treatment to correct myopia. This arm is set to be as a control group for the other two arms. Myopia patients who enter in this group will wear a normal pair of glasses after the baseline examinations (axial length, refraction...).
Spectacles
Normal spectacle lenses were used to correct myopia as the control group.
Myovison
Myovision is a kind of specially designed, commercially available spectacle lenses that could control the peripheral refraction of myopia patients. Latest studies have changed the understanding of myopia--correcting both central and peripheral vision during lens treatment is indicating to be an effective way of slowing down eye growth. Patients who entered this group will wear a pair of Myovision after baseline examinations.
Myovision
Myovision is a kind of specially designed spectacle glasses that could control the peripheral refraction of myopia patients. It is commercially available.
Ortho-K
Orthokeratology has recently been reported as an effective way to control eye growth for myopia adolescents. Patents who enter this group will wear ortho-K lenses during sleep after baseline examinations.
Orthokeratology
Orthokeratology lenses.
