Australians are spending more time in front of a screen than they are sleeping. According to a survey by Lonergan Research, almost a third of the day - 9.4 hours – is being spent exposed to blue light emitted from your computer, mobile phone and television screen. This screen time equates to an astonishing 143 days every year.
Blue light is a high-energy light emitted from digital screens, certain light bulbs, and even sunshine. Long hours of blue light exposure can be harmful to your peepers, including strain, dry or watery eyes and irritated eyes, all of which can lead to blindness. Blue light is also known to sabotage your sleep schedule because it messes with your circadian rhythm (AKA your internal clock that tells you when it’s time to sleep or be awake).
So, what’s the answer? Office workers tend to spend more time exposed to blue light than any other work environment, spending almost half the day looking at a screen – up to 11.4 hours. Blue light is all around us, which makes it impossible to avoid screens altogether.
