Visual Performance in Office
Optimal use of lighting has physical, physiological, and psychological effects on employee comfort, satisfaction and visual performances, and overall organizational productivity. Inappropriate lighting characteristics, such as lighting patterns and distribution, glare, flicker, colour appearance, culminate into one’s physical discomfort, visual fatigue, cognitive dysfunctions, and negative influence on satisfaction and task performance. This chapter describes the effects of lighting conditions on visual performance and anomalies. Prolonged viewing of display terminals and other hand-held electronic devices results in eye strain, ocular discomfort, diplopia, blurred vision, which are collectively referred to as computer vision syndrome. Contemporary research on the practices of office lighting systems, quality of lighting, and colour characteristics of office interiors is included in the chapter. A questionnaire is included to evaluate satisfaction and physical comfort, about the effects of lighting environment in office buildings. With reference to standard EN 12464-1 :2011, this contribution compiles recommended levels of illuminance, glare, uniformity of light and colour rendering quality, as related to the type of area, task, or activity.
