More light, more safety: Good lighting for senior living spaces

Changes in eyesight with age

With increasing age, eyesight changes noticeably. Pupils become smaller, the lens cloudier, and light sensitivity decreases. Less light reaches the retina, contrasts diminish, colors fade, and orientation becomes more difficult.
Targeted lighting design can be crucial here – it promotes safety, well-being and quality of life.

Why older people need more light

Older eyes require significantly higher levels of light. While around 300 to 500 lux is sufficient for young people, seniors benefit from up to a third more brightness.

Recommended are:

• Softly distributed, glare-free light through indirect lighting.
• Light ceilings and luminous walls create uniform brightness.
• Reduced shadow formation to avoid tripping hazards.
• This creates a visually pleasing environment that supports safety and orientation.

The biological effects of light

Light affects not only the eyes, but also the body's rhythms. Special ganglion cells in the retina control our circadian rhythm – the sleep-wake cycle – through the hormone melanopsin.

• Cool, blue-rich light during the day promotes alertness and concentration.
• Warm white light in the evening promotes relaxation and tranquility.
• Daylight-like lighting systems can simulate this natural progression.

This “melanopic effect” of light contributes to inner balance and has a stabilizing effect, especially in old age.

Orientation through spatial lighting design

For older people, not only brightness but also the spatial distribution of light is crucial. It helps them to perceive shapes, paths, and transitions more clearly.

• Broad, diffused light from the upper hemisphere ensures even illumination.
• Light ceilings and light walls create visual spaciousness and reduce the risk of glare.
• LED light frames highlight pathways or functional zones and improve orientation.

This creates a clear, low-contrast spatial structure with increased security.

Lighting design as a contribution to quality of life

Well-planned lighting offers far more support for older adults than simply improving their vision. It promotes:

• Safety and Mobility
• Concentration and activity
• Mood and emotional stability

Modern lighting solutions – such as dimmable panel lights, adaptive luminous ceilings, or sensor-controlled systems – bring the feeling of natural daylight back into interior spaces. The result is a harmonious, healthy lighting environment that promotes well-being and quality of life well into old age.
