Different lens treatments include normal spectacle lens, orthokeratology, and Myovision (a specially designed spectacle lens commercially available with peripheral defocus controlled as relative myopia). 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.
