Brief summary: In this study, the investigators aim to perform a prospective, randomized controlled study to compare the myopia development between myopia children using myopia prediction algorithm and myopia children without using myopia prediction algorithm

Detailed description: The investigators propose to enroll myopia children aged 8-10 in China. Children will be given examinations of visual acuity, eye refraction and biometrics, and be assigned to two groups: participants in group A use myopia prediction algorithm to predict myopia development, while in Group B, the participants do not use myopia prediction algorithm to predict myopia development. The visual acuity, eye refraction and biometrics will be investigated over the one-year follow-up period, aiming at comparison of actual myopia development between the two groups

Eligibility criteria: Inclusion Criteria:

* Children aged 8-10
* Has the record of eye refraction examined in the past year, SER\<-0.5D
* Current BCVA≥0.8, SER\<-0.5D, Astigmatism less than 1.50 D, anisometropia less than 1.50 D
* Written informed consents provided

Exclusion Criteria:

* Definitive diagnosis of other diseases except for refractive error
* Previous eye surgery
* Previous usage of orthokeratology lenses and atropine
* Unwilling to participate in this trial
