If you regularly use digital devices before bed, you might be disrupting your natural sleep patterns.

Smart devices have revolutionised the way we work, live and play. We’re increasingly using them to work, read books, surf the web and watch TV.

But studies show there may be a downside. LED-lit digital devices emit Bluelight – a short wavelength, high-energy light that naturally boosts your alertness, memory and feelings of wellbeing.1

Of course, that’s great news – during the day.

But, at night, Bluelight can disturb your natural circadian rhythm – or the ‘clock’ that lets your body know when to sleep and when to wake up.

The result is you may find it harder to get to sleep, experience more restless sleep and have trouble waking up (because you’re still tired).

Who’s at risk?

Anyone exposed to Bluelight after dark can experience sleep problems. We’re all guilty of taking work home now and then, or reading books and magazines on our tablets to wind down at night.

However, it’s probably no surprise that 63% of children and teenagers aged 5 to 17 regularly exceed the Department of Health’s recommended 2 hours of screen time per day, often at night.2

How does Bluelight affect my sleep?

Your body clock is particularly sensitive to the Bluelight found in sunlight and modern LED and fluorescent lighting.

Absorbed by the back of your eye (retina), Bluelight suppresses melatonin (a natural hormone that promotes sleep) to make you feel more awake during daylight hours.

As it gets darker, your body responds to the darkness by increasing melatonin and you start to feel ready for sleep.

But when you use a digital device at night, the Bluelight emitted can trick your body into suppressing melatonin, just like the sun does. It stops you from feeling fully ‘sleep ready.’

This makes it more difficult for your brain to know when it’s time to sleep. It also makes it more likely you’ll have interrupted or poor quality sleep.3

What can I do?

It’s pretty safe to say that digital devices are here to stay. And we wouldn’t want it any other way.

The good news is there’s now a simple way to reduce your exposure to Bluelight and help get a good night’s sleep again.

By wearing glasses with an added Bluelight filter, you can significantly cut down on the amount of Bluelight your eyes absorb at night.

Your Bluelight glasses will allow melatonin to be produced at the right time so you’ll feel naturally sleepy and ready for a great night’s rest.

Does it really work?

Research shows Bluelight lenses work exactly like sunglasses – but instead of cutting down harmful UV rays during the day, you’re reducing the effects of Bluelight wavelengths at night.

For example, in 2014, a Swiss study found that, compared with clear lenses, glasses with an added Bluelight filter significantly increased melatonin and decreased alertness before bedtime for adolescents who used digital devices.4

Other studies report similar results.5, 6 The filter looks clear but prevents your retina receiving the Bluelight wavelengths. It’s safe to use and can be worn day or night.

What if I don't wear glasses?

If you don’t wear prescription glasses for reading, then a low cost, non-prescription pair of glasses with a Blue light filter may help get your body clock back to its natural rhythm. Or if you wear contact lenses, these non-prescription Blue light glasses can simply be worn over the top!

If you do currently wear prescription lenses for near tasks like reading, a filter can be added when you get your next pair of glasses.

What is Bluelight?

Bluelight – a short wavelength, high-energy light that is emitted by the sun, LED and fluorescent light and digital devices. When it’s absorbed by the back of your eye (retina), it naturally suppresses melatonin – a hormone that makes you feel sleepy. During the day, Bluelight makes you feel awake so you can get more things done. However, at night, too much Bluelight can make you more alert and disrupt your natural sleep patterns.

Do my Bluelight glasses come with a warranty?

If there is a defect with your product within 12 months of purchase, we’ll replace or repair them for free – regardless of any manufacturer warranty exclusions that may apply.
