电光性眼炎是紫外线照射后引起的,凡是和紫外线有关的工作,如电焊、气焊或实验室用的紫外线灯都能发射紫外线。紫外线是一种看不见的射线,其中波长在320～250nm 的紫外线最容易被角膜和结膜上皮吸收,致角膜上皮坏死脱落,引起光电性损伤.
Electro-optic ophthalmia is caused by ultraviolet radiation, and any UV-related work, such as welding, gas welding or laboratory UV lamps can emit ultraviolet light. UV is an invisible ray, of which the wavelength of 320 ~ 250nm UV is most easily absorbed by the cornea and conjunctival epithelium, causing corneal epithelial necrosis, causing photoelectric damage.
