环境光的光谱组成对屈光发育的影响研究进展

Research progress of ambient light’s spectral composition in refractive development

近视作为屈光发育异常中最常见的一种屈光状态,不仅给个人和社会造成一定的经济负担,而且还增加了患近视性黄斑变性等损害视力疾病的风险。研究表明,不同光谱组成的光可以通过改变眼的调节、脉络膜厚度以及视锥细胞信号转导等来影响眼的屈光发育,改变近视进展。主流的观点认为增加短波长光含量有利于延缓近视的进展,但也有学者对此持不同的观点。本文总结环境光的光谱差异对屈光发育的影响及相应的眼部改变,为后续的研究提供参考。

Myopia,as the most common refractive state in refractive errors,not only brings huge expenses to individuals and society,but also increases the risk of vision impairment diseases such as myopic macular degeneration.Studies have shown that light with different spectral composition can affect the refractive development and myopia progression by changing the visual accommodation,choroidal thickness,and signaling of cones.Most researchers insisted that increasing the contrast of short-wavelength light can delay the progression of myopia,but some held different views.This paper summarizes the effects of spectral differences in ambient light on refractive development and the response of eyes under different ambient light,providing a reference for subsequent research.
