Ophthalmological aspects of workplace lighting by fluorescent tubes only
Der ausschliesslich durch Leuchtstoffröhren beleuchtete Arbeitsplatz aus ophthalmologischer Sicht [en alemán]
Measurements carried out in precision engineering shops where the lighting was provided exclusively by fluorescent tubes were evaluated against complaints made by 107 workers. A relation was established between problems of vision, on the one hand, and inadequately corrected refraction problems, insufficient light intensity, high visual requirements and visual stress, on the other. Psychosomatic rejection of purely artificial light is attributed to the non-physiological quality of such light and to attendant hormonal factors. Recommended improvements: supplementary lighting, minimum illumination levels, optimum correction of vision, good contrast, proper choice of colour of light.

Natural lighting of work premises by rooflighting
Natürliche Beleuchtung am Arbeitsplatz durch Oberlichter [en alemán]
The relations between performance, fatigue and behavioural errors, on the one hand, and illumination levels, on the other, are demonstrated with illustrations, and the factors affecting natural as opposed to artificial lighting are analysed. Rooflighting enables full use to be made of the high degree of luminance from natural zenithal light and provides a more even light distribution than light from windows. This is demonstrated by diagrams, charts and calculations. Rooflighting of the working surface may, however, be limited by the dimensions of he premises, skylight design, glazing materials used and accumulated dirt on skylights.

Optimisation of vision and "visualising light sources"
Optimalisation de la vision et "lumičres visualisantes". [en francés]
Studies since 1956 in a large number of workers undertaking a precision task on miniaturised micro-electronic units are reported. Experiments are reported that lead to a theory of "visualising light sources" (spectral bands at the edge of the visible spectrum which enhance the efficiency of lighting and thus improve vision). This may be of value in the ergonomic solution of lighting problems at the workplace.

Ergonomic criteria for lighting at the workplace
Critčres ergonomiques d'éclairage en situation de travail. [en francés]
Performance of visual tasks is a function of the detail involved, illuminance, operator's age, specular reflection of background, duration of task, and the general light environment (absolute values and balance of luminance levels, contrast of luminance, colours). Conditions that the visual quality of an installation must satisfy are the quality of luminance contrasts, colour rendering, and balance between the various types of lighting. Practical recommendations are given for determination of optimum illuminance, avoidance of glare and light-shade transitions, choice of luminance sources, and maintenance of lighting equipment. Appendices: recommended illuminance levels; calculation of luminance limits of luminaires; photometric characteristics and use of lamps.

Arbetsbelysning i gjuterier och smältverk - belysningsunderhĺll, redovisning av resultat frĺn lĺngtidsprov [en sueco]
Studies over more than a year of 8 types of luminaires installed at 43 foundries, and a questionnaire survey of maintenance practices, are reported. Considerable differences were noted in the degree of soiling due to deposited smoke and dust, depending on luminaire design. The least soiled were those with ventilation. Open reflectors are not suitable for foundries as they are get dirty too quickly. The light output of lamps in closed luminaires fell more quickly than that of those in open ones. Thorough cleaning of luminaires once a year considerably improves lighting conditions.

Choice of models for visual tasks with different levels of precision
O vybore modelej zritel'noj raboty različnoj točnosti [en ruso]
A model to standardise experimental conditions for evaluating workload is presented. It comprises 4 quality-control tasks (normal and defective metal, plastic, paper and fabric objects). Controls were carried out in free working conditions with illumination levels of 70-2,500lx. Assessment of visual fatigue under industrial conditions showed that an hour and a half devoted to the tasks proposed produced the same visual fatigue as a day's work at a high-precision task. The model should permit better comparison of results of psychophysiological studies.

Lighting and optical physiological problems of work with data display screens
Lichttechnische und physiologisch-optische Probleme bei der Arbeit an Datensichtgeräten [en alemán]
Rapid shifting of the field of vision from the screen to a brighter surface area (e.g. window or manuscript) gives rise to a visual adaptation problem. This adaptation can be facilitated by increasing the size of the characters on the screen and having a luminance ratio between the screen and the environment of 1:3 to 1:4. The possibility of improving screen luminance is examined. Glare and its suppression are very important. Problems of presbyopia can be resolved with corrective lenses suited to the various work distances. Other recommendations are made for the distance between the screen and manuscript, and visual fitness examinations.

Study of working capacity and examination of visual functions during work performed on polished metal surfaces under different lighting conditions. Prolonged work with lighting conditions producing glare results in considerable visual fatigue and reduced visual functions. The most favourable range of luminance for the perception of a bright object on a dark polished surface falls between 1,500-2,500cd/m2. Visual fatique due to this type of work can be evaluated by means of indices such as constancy of visual functions, visibility and sensitivity to luminouus and electric stimulations.

Light and colour at the workplace
Licht und Farbe am Arbeitsplatz [en alemán]
The influence of light and colour on comfort and work capacity and safety is well established scientifically. The requirements for good lighting are set out: luminance and visual acuity, reflectance, elimination of glare, light and colour contrast, utilisation factor. A large section is devoted to the colour climate: colour temperature, colour of workplace surfaces, effects of colours, colour of light, colour rendering, use of safety colours for signs. The importance of other factors such as the construction elements, type of work, daylight, is mentioned.

Lighting of workplaces in foundries and the iron and steel industry - Finish cleaning and inspection/reception
Arbetsbelysning i gjuterier och smältverk - finrensning och kontroll-avsyning [en sueco]
Workplaces in 3 foundries were studied. Finish cleaning and inspection of castings require great visual effort and may be classified as precision tasks. The work is made difficult by poor contrast between the surfaces of the piece, grains of sand adhering to the surface, and shadows cast into the cavities. The improvements made at the workplaces are described: local lighting with antiglare screens, arrangement of local lighting luminaires on 2 or 3 sides, increased illuminance levels, adjustable luminaires, use of light tables with the light under an opaque surface or a movable light source using optic fibres.
