Szukana fraza: [Abstrakt = "Longer professional activity of people in aging populations forces changes in the work environment. Lighting conditions should be tuned to meet specific preferences of the elderly workers. Apart from the essential high levels of illuminance needed, a question of a proper correlated color temperature \(CCT\) of light seems to be worthy of consideration. In this study, the visual performance of twenty persons aged 58\-73 years old was examined in two lighting conditions provided by fluorescent lamps of CCT 2700 K and 6500 K, both lamps of color rendering index \(CRI\) 82. Ophthalmologic tests were applied and assessments of legibility and symptoms of fatigue were compared. Elderly people discriminated hues much better at CCT 6500 K than at CCT 2700 K. For achromatic visual tasks, a slight advantage of the CCT 6500 K light was observed. Subjective assessments favored the CCT 6500 K also. Lighting sources with high CCT seem to be better suited to elderly workers."]
