[Hygienic evaluation of the work of technical school students on the video display terminals].

Psychologic and hygienic examination of students working on display calculating complexes (DCC) DCC-2 and DCC-3 during the extra study time revealed the features of their functional status caused by the DCC design and work schedule. Positive role of eye exercises during the work was stressed. 6-hours duration of students' work was considered as unfavourable. The duration of work must be reduced to 3 hours, prophylactic measures (eye and physical exercises) are to be added.

Computer-specific spectacle lens design preference of presbyopic operators.

Twenty-nine presbyopic subjects who spent at least 20 hours a week at a video display terminal compared a progressive addition lens designed for this function, with another commonly prescribed task-specific lens. Each of the paired lens types was worn for 4 weeks and then compared directly for 1 week. A statistically significant (P < .05) portion of the subjects (76%) preferred the task-specific lenses overall. It also was preferred more frequently for each feature compared, although the difference was statistically significant (P < .05) only for utility of distance vision. Both of the task-specific designs contributed to symptomatic relief. The presence of a distance-clear zone and the absence of lens discontinuities most likely account for user preference for the task-specific lenses. That preference suggests improved performance for presbyopic computer users wearing task-specific progressive addition lenses.

[Analysis of the place of regulation of C-11 transmitters at the Tele-electronic Works "Telkom-Telfa" in Bydgoszcz from the point of view of visual hygiene].

The authors performed a detailed analysis of 100 positions of regulation of the C-11 transmitters in the "Telcom-Telfa" ++Tele-electronic Works in Bydgoszcz. It was determined that the requirements for the condition of the eyes and the lighting at this workstand are considerable. Conclusions and recommendations tending to improvement of the working conditions are drawn up. Proposed is eventual rationale leading to the reduction of the eyestrain and facilitation of the work.

[The dependence of the degree of visual fatigue on the shift duration in work with video terminals and an assessment of the efficacy of preventive measures].

Dynamic studies of visual capacity for work in individuals working with displays revealed decreased accommodation volume after the long concentration on the display. The total time of work with the display of more than 2h a day involved a decrease of the accommodation volume by 0.42-0.49 diopters and transitory myopia of 0.15-0.21 diopters, as well as increased self-appraisal of fatigue. The system of prophylactic measures including rest breaks, special exercises, massage was worked out and put into practice. Repeated study has proved the effectiveness of suggested measures.
