Today we’re covering blue light filter glasses. With more and more people working from home and having increased amounts of screen time, for both adults and kids, this is a good opportunity to provide more information. I’m sure we’ve all either heard of them, know somebody who wears them or are curious to find out if they’re worthwhile, so read on to find out more.
With a surge in technology use, whether that be to complete work tasks or FaceTime family members, our average screen time consumption has increased BIG TIME. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
Whether you’re looking at a laptop, cell phone, TV or tablet, these devices all have one thing in common. They give off Light-Emitting Diodes (what we know as LEDs!) which emit blue wavelengths of light. More so than any other colour on the spectrum, blue light greatly affects our body’s ability to prepare for sleep. How? It suppresses melatonin. Here’s a quick breakdown:⠀⠀⠀⠀⠀⠀⠀⠀⠀
✨MELATONIN IS PRODUCED BY YOUR BRAIN TO REGULATE YOUR BODY’S SLEEP/WAKE CYCLE ⠀⠀⠀⠀⠀⠀⠀⠀⠀
🌚 DARKNESS ENCOURAGES YOUR BODY TO PRODUCE MORE MELATONIN ⠀⠀⠀⠀⠀⠀⠀⠀⠀
🌚 MORE MELATONIN PREPARES YOUR BODY FOR SLEEP ⠀⠀⠀⠀⠀⠀⠀
🌞 LIGHT DISCOURAGES YOUR BODY FROM PRODUCING MORE MELATONIN ⠀⠀⠀⠀⠀⠀⠀⠀⠀
🌞 LESS MELATONIN PREPARES YOUR BODY FOR BEING AWAKE ⠀⠀⠀⠀⠀⠀⠀⠀⠀
Researchers at Harvard Medical compared the effects of exposure to blue light versus exposure to green light. They concluded that blue light suppressed melatonin about TWICE as long as green light! They also found that the blue light exposure shifted the subjects’ circadian rhythm (sleep/wake cycle) 2x as much! ⠀⠀⠀⠀⠀⠀⠀⠀⠀
In saying this: TRY TO AVOID LOOKING AT BRIGHT SCREENS 2-3 HOURS BEFORE BED. If you can’t nip the screen time, WEARING BLUE LIGHT FILTER GLASSES AND/OR APPLYING A BLUE LIGHT FILTER TO YOUR DEVICES after sunset can greatly help your body prepare for a better-quality sleep.
