强光疗法和结合近视失焦治疗的有效性,以控制学龄儿童近视眼的生长:随机对照试验 (第一阶段) 的研究方案

The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
