光对视网膜的损伤包括热灼伤、光化学损伤和机械损伤三种方式。因为眼内组织色素分布的差异,蓝光主要在神经上皮层吸收,主要引起视网膜光化学损伤;绿光在神经上皮和色素上皮的吸收相近;黄光主要在色素上皮和脉络膜浅层被吸收;红光则作用得更深,主要引起热效应;而高能量的激光可
Light damage to the retina, including thermal burns, photochemical damage and mechanical damage in three ways. Because of differences in the distribution of pigment in the eye tissue, blue light is mainly absorbed in the neuroepithelial layer and mainly causes photochemical damage to the retina; the absorption of green light in the epithelium of the epithelium and the pigment epithelium is similar; the yellow light is mainly absorbed in the pigment epithelium and the choroid superficial layer; Then the role of deeper, mainly caused by thermal effects; and high-energy laser can be
