[The effect of painful dazzle on the perception process]

Perception is an active process of receiving, analysing and interpreting visual information coming for the environment. Particularly, in occupational activities which require great visual efficiency, obtaining of proper visual information, determined by a correct process of perception is extremely important. An optimal lightening of the workpost is one of the essential factors determining correct perception. However, various parameters of the luminous environment may have a negative effect on visual processes. Painful dazzle belongs to one of them. It is claimed by workers as the feeling of annoyance, lack of concentration and visual discomfort. The work presented proves a possible negative effect of painful dazzle on the perception process, and consequently on the occupational performance and even on workers health.
