What is blue light?

How is it affecting me?


People are spending more time than ever in front of digital devices. In fact, they’re spending around 7.5 hours a day if we want to get technical. We are constantly rotating between our phone screens, computer screens, and televisions. It seems this dangerous cycle is becoming a norm in our everyday routine, whether we like it or not.

As we become more and more consumed by our devices, I think we can all agree this digital addiction is starting to take a toll on our psychical and mental health.

As we navigate our way through this digital world, the most important thing we can do is take the necessary steps to ensure our digital journey is a safe one.

What exactly is blue light?

To put it simply, blue light is a short, high-energy wavelength in the visible light spectrum. This electromagnetic spectrum is made up of wavelengths of varying lengths, seen as colours by the human eye. Every wavelength is represented by a different colour: violet, indigo, green, yellow, orange, red or blue.

Blue light is the highest frequency visible to the human eye. It is positioned at the top of the light spectrum and is very close to Ultraviolet light – well known for causing damage.

Blue light is natural and can be found everywhere. Sunlight is the main source and the way most people get exposed. The wavelength of blue light is very short, and due to its high energy, it scatters very easily when it meets air and water. This is why we can thank blue light for the colour of our sky

Why you need blue light glasses?

Let’s be real, we are an ambitious bunch. We live in a society full of creators and innovators, and the likelihood of us cutting down our screen time completely is unlikely. So, instead of cutting out the problem, blue light glasses are here to support us on our digital journey. Think of them as sunscreen for your eyes.

Better sleep

Who doesn’t want to wake up feeling refreshed and energised? Similar to the way the sunlight can help you feel alert and energised throughout the day, blue light has the same effect. Due to blue lights short wavelengths and high energy, it delays the release of melatonin in the body, which is a sleep-inducing hormone that allows us to wind down and fall asleep, as well as enjoy deeper and longer periods of rest. 

As you can imagine blue light, particularly before bed, can greatly affect our sleep cycle by making us more alert and less likely to wind down. If you can, try putting down your devices two hours before bed, but if you simply can’t help scrolling through your socials, then blue light glasses will be your new best friend.

Baxter Blue’s amber Sleep+ TM lenses have been specifically developed to filter out the blue light wavelengths that impact the release of melatonin. So with a little help from these guys, you’ll be nodding off in no time.

Reduce digital eye strain

Looking at your digital devices all day not only makes you feel stressed and irritated, but it also causes significant muscle strain on your eyes.

When you look at a screen the muscles in your eyes tighten in order for you to focus and process information. This is because short wavelengths are emitted from the screen causing you to squint unconsciously, and in turn leading to blurred vision, headaches, and poor concentration. Blue light glasses help to filter out harmful wavelengths as well as increase contrast on your screen, making it easier to focus and subsequently reduce eye strain.

Fewer headaches

All types of light, particularly blue light, can trigger migraines and intensify headaches. This can also occur from the tightening of our eye muscles to focus information on our screens. By simply filtering out blue light from our screens through blue light glasses we can greatly reduce the likelihood of migraine attacks and headache pain.

It’s obvious our devices are here to stay, so stop putting it off and join the digital wellbeing revolution. Take the first step towards healthy eyes.

When buying blue light glasses you want to ensure they are good quality, after all, if this blog has taught us anything, it’s that there are some serious consequences of not looking after your eyes. Thankfully Baxter Blue has done the hard work for you. They’ve designed a wide range of top of the line, stylish blue light glasses to protect your eyes from the damaging effects of blue light, while reducing glare and increasing contrast. And since our kids are now being exposed to these harmful rays from such a young age, they’ve also developed a kids’ range. Protect yourself, and feel free to make the most of the benefits of the digital age.
