While you may have heard that blue light can be detrimental to our health, you’re probably not aware as to why. So let’s delve deeper into this topic so we can get to the bottom of this controversial topic. 

To understand blue light, it’s best to start with sunlight, which is made up of various colours with different energy and wavelengths. When combined, this becomes the white light we see. Rays on the red end have longer wavelengths and less energy while those on the other, blue end have shorter wavelengths and thus more energy than other colours in the visible spectrum.

It’s the make up of these higher-energy wavelengths that means - in high enough doses - blue light is more likely to cause damage when absorbed by cells in eyes. This is bad news for those that find themselves glued to modern devices like smartphones and laptops, as the LED lighting used in their displays produce a great amount of blue light. As a result, there is concern over the long-term effects of screen exposure because of the close proximity of the screens and the length of time spent looking at them.

And so, for gamers, understanding how light is structured, how modern screens work, and how the eye reacts to them, can help us build a healthy lighting environment during gameplay that will have minimal impact on player performance.
