The human eye evolved under very different circumstances than those we live in today. Most people use their eyes for a vast number of close tasks every day: reading, close work and ever increasingly, tablets, televisions, computers and smartphones.

Furthermore, this light is different in composition to natural or even artificial light, in particular the percentage of blue light is much higher. While blue light is part of the natural spectrum computer and TV screens are a powerful source. Excessive exposed to blue light can cause red and irritated eyes, headaches and fatigue.

Concentrated blue light, especially in the late evening (for example, caused by working late or watching TV just before you sleep) can confuse your body producing sleeplessness. Your eyes send signals to your body that it is daytime, waking you up!
It’s difficult to change your lifestyle and it seems like digital screens may become more and more part of our lives.

They neutralise blue light proving more comfortable vision as well as more natural colour perception when you are using digital devices.
