Our eyes are less good at filtering out the artificial light we spend our days looking at than they are at filtering out the ultraviolet light of sunshine. Digital screens, LED and fluorescent lighting all emit blue light, which contains more energy than red or orange light and is known as high-energy light. But while blue light helps to keep us awake during daylight hours, constant exposure in our offices and from our devices can add up. The more time we spend in artificial light, the more discomfort we can experience. Our eyes weren’t designed to look at screens, and long hours at our computers can cause headaches, eye strain and technostress.

Our eyes weren’t designed to look at cityscapes either. Studies on the effect of colours on emotions have shown that we find the blues and greens of nature the most restful. They make us less anxious and reduce our stress. The greys of an urban scene, however, have been shown to make us unhappier and more aggressive.
