It is well known that vision deteriorates with age. Far less widespread is the knowledge of how early this process begins. It already starts slowly from the age of 30: color and depth perception diminish, and it takes longer to adjust to differences in brightness. To see well, a fifty-year-old already needs more than three times as much light as a twenty-year-old. Higher illuminance levels at work and at home help to compensate for weaker visual performance, advises the industry initiative licht.de.<\/p>\n

For good visibility, \"fixed lighting\" does not have to be switched on around the clock, especially in times of energy shortage at home. But for certain activities, light sources with higher illuminance levels should be available - for example, for work in the home office, at the mirror in the bathroom or in the kitchen to avoid accidents with sharp measurements and hot pans. Dimmable lighting is ideal for a good working or cleaning light and a comfortable lighting atmosphere in the evening.<\/p>\n

No glare<\/h3>\n

The older eye is more sensitive to glare. Obstacles are easily overlooked and the risk of falling increases. High-quality luminaire covers and a high proportion of indirect lighting reduce glare. When changing from light to dark, the eyes need longer to adapt with increasing age.<\/p>\n

Work ergonomically<\/h3>\n

To recognize colors correctly at work, light sources with very good color rendering (at least Ra 80) are needed. For the workplaces of older employees, the workplace standard DIN EN 12464-1 recommends higher, modified values. They can be retrofitted quite easily with additional desk, workstation or floor luminaires. Good lighting design plans for these requirements from the outset. With a lighting control system, the design is implemented in an energy-efficient manner. For example, if not all workstations in an office with several networked free-standing luminaires are occupied, the luminaires that are temporarily not needed dim to a less bright, indirect light. This means that there are no excessive differences in brightness and employees can still find their way around.<\/p>\n

Incidentally strengthen the biorhythm<\/h3>\n

If you have luminaires and lamps at home with several settings for brightness and light color, you can also do something good for your biorhythm. Bright, cool light in the morning gets the body going, and dimmed reddish light toward evening lets it rest. In this way, the internal clock is synchronized, well-being increases and night sleep can improve.<\/p>\n

\n
\n

In workplaces, the lighting management system controls these and other parameters for lighting with visual, biological and emotional lighting effects completely automatically. The integrative lighting concept behind this is called Human Centric Lighting (HCL). Older employees in particular benefit from this: because less and less light reaches the eye over time due to the clouding of the lenses, the positive, light-induced activation of biological processes in the body is weaker in them.<\/p>\n
