Why you need blue light blocking glasses

It’s time to give your eyes a holiday…  

If you’re anything like us, you’re a ‘multi-screener’; you watch TV with a phone in your hand and sometimes your tablet. Or perhaps, you’re on your laptop, while playing with your smart watch and talking on your phone. Either way, it’s pretty clear that one screen is never enough.

Well, according to a recent survey from Unilever Skin Care Research, we’re not alone. Apparently millennials check their phone up to 150 times and clock up more than 10 hours of screen time a day.

Sleep specialist Olivia Arezzolo says this sleep deprivation can be largely attributed to the effects of ‘blue light’ emitted from our devices.

“Excessive daytime exposure [to blue light] from screens such as laptops and phones equates to an over stimulated brain, which prevents us from resting properly in the evening,’ she explains.

Arezzolo believes that in order to attain quality rest – where we restore our happiness hormones dopamine and serotonin – we need to experience ‘slow wave sleep’, which is essentially a calm, tranquil brain. However, she says, exposure to blue light prevents this, meaning you’re unable to reach that deep state of sleep.

While experts suggest the answer is cutting down on our screen time, we know that’s pretty unrealistic. Luckily there is another option; blue light blocking glasses. These specially designed glasses have filters in their lenses designed to block or absorb disruptive blue light coming through.

And they’re nothing new. Back in 2009, one study even found that wearing blue light blocking glasses at least three hours before bedtime promoted better sleep quality and mood.

Australian brands like Local Supply and Quay have caught on, ensuring the latest iterations don’t look bad either. (links, STLs)

So if you’re a night owl that loves a bit of screen time, or if you spend long hours on your devices and find you have trouble sleeping, blue light blocking glasses just might be what you’re looking for.
