IMPORTANCE: Treatments are needed to slow progression of or reduce incidence of myopia.

OBJECTIVE: 评估近视治疗的每日650 nm低级红光（LLRL）的功效和安全性。

设计，sett，settING和参与者： 在中国1个地点进行的单罩，随机临床试验。 Baseline measurements were completed from August to September 2021. Participants were children aged 6 to 12 years with spherical equivalent error (SER) of -6 diopters (D) to 3 D. Data were analyzed from March to July 2023.

INTERVENTIONS: Irradiation daily with 650-nm LLRL for 3 minutes每天两次相隔4小时或不干预。

主要结果和措施： 主要结果是在6-和12个月的随访访问中的Cycloplegia Ser和轴向长度（Al）长度（Al）长度（Al）的变化。对掩盖的底面照片评估进行了评估。
