Lighting Fact #27

Let’s face it, we all get older. The trick is to go through it and do it properly and in a healthy way. Light is last but not least in this story. 

With age, the eye becomes less transmissive, especially for short wavelength (blue) light. Therefore lighting environments should be brighter for elderly (for vision and chronobiology) and blue-enriched. For example, a 50-year old person should be projected 40% more light than 25-year old and a 80-year old person — 100% more light than 25-year old.
