The condition of the lens was studied in 1210 workers of steel industry: in 455 workers of an open-hearth shop (OHS) and in 755 workers of oxygen-converter shops (OCS). The intensity of infra-red irradiation was measured at working places in both shops by non-selective radiometer ARGUS-03. A higher level of automation and more advanced technological processes in the OCS ensure a better protection of the organ of vision of the OCS workers from the impact of infrared irradiation. Thus, the OCS workers had a lower occurrence of cataract development and a less intensity in changes of the lens as compared to the similar parameters registered in the OHS workers. The cataract development was proven to be directly dependant on a labor record length: changes in the posterior capsule and opacifications of the lens posterior cortical segments (stages I and II) were observed in those, whose labor record ranged from 10 to 15 years; brown changes in the nucleus and dystrophic changes in the anterior capsule (degree III) were found in those, whose labor record exceeded 15 years.
对1210名钢铁行业工人的晶状体状况进行了研究：其中455名来自平炉车间（OHS），755名来自氧气转炉车间（OCS）。使用ARGUS - 03型非选择性辐射计在两个车间的工作场所测量了红外辐射强度。OCS车间更高的自动化水平和更先进的工艺流程确保了OCS车间工人的视觉器官能更好地免受红外辐射的影响。因此，与OHS车间工人记录的类似参数相比，OCS车间工人白内障发病率更低，晶状体变化程度也更小。事实证明，白内障的发展与工作年限直接相关：在工作年限为10至15年的工人中观察到晶状体后囊膜变化和晶状体后皮质段混浊（I期和II期）；在工作年限超过15年的工人中发现晶状体核呈棕色变化和前囊膜营养不良性变化（III度）。
