红外辐射致晶体混浊的形态,多数学者认为混浊部位初起于后极囊下皮质,呈空泡、点状和线状,以后扩展成网状、盘状,最后波及全晶状体,也有报道从周边开始的。为了探讨热辐射对工人视觉的影响,观察红外辐射白内障与钢铁工业高温作业环境的职业联系,以及在工人中的分布特征,探索引起红外辐射 Infrared radiation caused by crystal opacity, most scholars believe that the turbid sites began in the posterior subcapsular cortex, vacuoles, punctate and linear, later expanded into a network, disc, and finally affect the whole lens, also reported from the periphery The beginning. In order to explore the impact of thermal radiation on the visual of workers and to observe the occupational relationship between infrared radiation cataracts and high temperature operating environment in the steel industry and the distribution characteristics among workers,
