[Evaluation of lens transparency in persons exposed to electromagnetic radiation of 27--30 MHz frequency].

55 women occupationally exposed to lasting electromagnetic radiation at 27--30 MHz frequency and 101 persons from control group were examined with reference to the status of lens transparency. No statistically significant differences between the frequency of lens opacity in the exposed and control group were found. No dependence of opacity on duration of employment was found, either. An increase in lens opacity was proportional to age both in the exposed and control group.
