An antidote to the modern age woes of screen time and sleep deprivation, blue light blocking glasses are the latest tool in our quest for eye health and the perfect nights sleep.

what is blue light

Smartphones, tablets, tv’s and LED lighting all emit blue light, which is a natural light - it’s present in daylight and helps us feel awake during the day, boosting attention and mood. In fact blue light rays are even used in light therapy to treat seasonal affective disorder (SAD).

Here’s the science.. blue light is one of the shortest, highest-energy wavelengths and blue wavelength light stimulates sensors in your eyes which send signals to your brain’s internal body clock.

Being online during the evening ensures our nights are now as illuminated as our days. The eyes are not very good at blocking blue light, allowing it to pass straight through to the retina, this disrupts melatonin and negatively impacts our sleep.

blue light and sleep

As more important research comes to light, we’re beginning to realise the huge importance of sleep for good health. Not only for brain function like concentration, productivity and performance, but to prevent serious illness like cancer, diabetes, heart disease and obesity. Sleep impacts every area of our lives, so in 2024 we all know the importance of prioritising our sleep.

One study found that sleep deprivation can affect brain function to a similar degree as alcohol intoxication, so missing out on a few hours shut eye is equivelent to a night on the fizz - madness!

Blue light suppresses the brain’s release of the hormone melatonin, a sleep inducing hormone, so artificial night time light throws out our body's biological clock, the circadian rhythm.

Poor sleep can cause so many health issues, so we need do everything we can to secure a good nights sleep and blocking out blue light in the evening can help achieve this.

Wearing your blue blight blocking glasses in the evening as part as your sleep hygiene routine, while watching tv, working late or working your way through the gram, can help prevent that screen light getting through and wrecking your sleep.

blue light and Screens

Many of us spend more time at our screens than actually sleeping (even though we know which is the healthier choice).

As our world becomes more digital the average person is spending at least 3 hours online everyday, from computer screens to updating social media during down time. This can cause digital eye strain, so along with investing in some computer glasses, we need to adopt healthy screen habits starting with…

Staring at our devices without blinking for long periods will cause eye strain so take regular breaks -

follow the 20-20-20 rule: every 20 minutes, shift your eyes to look at an object at least 20 feet away for at least 20 seconds. 

We’re all guilty of the the screen hunch which wreaks havoc on our entire body. Position your screen at arms length and straight ahead, consider taking up yoga to counteract sitting for long periods.

Do mindful screen-time after 9pm, so ban the late night insta scrolling and Netflix binging and pick up an actual book to help you get that good nights sleep.

Challenge yourself to a digital detox at the weekends or a digital free day - good for the eyes and the soul.

avoiding eye strain

When we’re screening and scrolling we blink less, which can cause eyes to dry out. Computer Vision Syndrome describes symptoms of sore dry eyes, blurry vision, difficulty focusing, headaches or a lovely combo of all of the above. You can minimise the effects by using screen glasses and prevent it by following these eye tips..

Adjust your lighting on your screen brightness and your screen contrast to suit. Make sure that your screen isn’t brighter than the surrounding light, or your eyes will have to work so much harder to see.

Adjust your room lighting, natural light is always best, face away from windows and lights.

Blink more - make a conscious effort, we forget when we’re staring at cute croissant pics and it helps prevents fatigue and dry eye.

Get outside and expose yourself to lots of bright natural daylight during the day to expose your eyes and reset your rhythms.
