Getting to grips with blue light

The coronavirus pandemic has definitely changed the way we use digital devices, apps and tools. In order to safeguard our health, we’ve had to adapt to less in-person social interaction whilst spending more time than ever looking at screens to communicate, do business and entertain ourselves.

Over the past year the term “blue light” has been popping up on numerous online platforms and even though there has been a lot of talk about its emission from digital devices, many still wonder what blue light actually is.

Blue light is a constituent of white light that we get from the sun, together with red, orange, green, violet and indigo. This is referred to as the Visible EM Spectrum and at the end there is UV light that cannot be seen by the human eye. The energy of these light waves increases as we go towards the end of the spectrum, making blue light one of the high intensity types of visible light.

Our eyes’ natural filters do not provide us with enough protection for blue light which is present everywhere. LED devices emit stronger blue light than what we get from the sun, hence spending hours staring at a screen leads to eye strain and fatigue.

Our brains use blue light to distinguish between day and night. This means that spending too much time on gadgets with illuminated displays late at night, fools our body into thinking that it should stay awake, thus negatively affecting the quality of our sleep. Blue light also hinders the product of Melatonin; a hormone which helps to regulate our sleep-wake cycle.
