||Work at visual display units: Who needs special glasses for work at cathode ray terminals?

||The survey used as a basis for drafting Directives No.136 of the Swedish National Board for Occupational Safety and Health concerning the prevention of visual disturbances in cathode ray terminal work (CIS 79-554) showed that 54.8% of CRT display terminal operators complained of these disturbances. This article gives advice on the recruitment of CRT operators, with early screening for refractory disorders and complete eye examination. Adaptation of prescription lenses presupposes the precise determination of the distance between the eyes and the distance between the lense and the pupil. When adapting the frame, the angle of vision should be taken into account, because selecting the wrong angle would result in prismatic deformation of the image, usually causing headache. The advantages and disadvantages of multifocal and progressive lenses are considered, and the importance of close collaboration between the ophthalmologist, the optician and the health and safety officer.
