Blue light itself isn’t bad – but it’s all about timing.
Natural blue light from the sun is beneficial during the day. It helps keep us awake, alert, and regulates our natural body clock.
Artificial blue light from screens – especially in the evening – is the real problem.
Exposure to screen light at night, makes your brain thinks it’s still daytime. This suppresses melatonin, the hormone that helps you fall asleep.
The result? Trouble falling asleep, poor sleep quality, and tiredness the next day.
Blue light blocking glasses filter out this artificial light, so your body can relax and follow its natural rhythm – even if you’re using a screen in the evening.
