盲法:

双盲,受试者及研究者均不知晓镜片设计,验配者进行试戴验配确定参数后,由第三方进行眼别随机,确定最终哪只眼使用反转弧设计镜片,哪只眼位常规设计镜片。

Blinding:

Double-blind, both the subjects and the investigators were unaware of the lens design, and the fitting participants were fitted to determine the parameters of the orthokeratology lens. The third party performed eye randomization to determine which eye used the reverse arc lens design and which eye used the conventional lens design.
