Let’s be honest, since we entered the hybrid working lifestyle, we’ve been spending a lot more time slouched in front of our screens. Whether it’s watching endless amounts of Netflix, hitting up the newest video games or trying to smash out some proposals while you work from home, we’re constantly surrounded by technology.
Recent studies suggest the average Australian spends close to 10 hours a day looking at digital screens. It’s the 21st Century dilemma; the rise of technology has made our lives more convenient than ever, improving almost every facet of our everyday existence, but at what cost? Sure, we know how important it is to get out every now and then for a bit of exercise and vitamin D, but beyond that, what else can we do?
It turns out one potential issue working from home presents is the often-overlooked issue of blue light. We’ve collated the information you need to know about blue light and which blue light glasses can potentially help you to fight the effects. But before we kick-off, the question remains; what is blue light?
What is Blue Light?
Blue light is a common form of light that is emitted from a range of natural and artificial sources. The phenomenon is all around us, permitted by the sun and by our digital devices, tablets, smartphones, TVs, computers and even some energy-efficient lighting. Sunlight, for example, contains many shades of red, orange, yellow, green and blue light rays, which vary depending on the energy and wavelength of the individual rays. When combined together, the spectrum of coloured light rays creates a phenomenon known as ‘white light’, which we refer to as sunlight.
It’s important to note that different light rays have different wavelengths, which means varying levels of energy. On a very basic level, light rays on the red end of the visible light spectrum regularly have longer wavelengths and therefore, less energy, compared to rays on the blue end of the spectrum, which have shorter wavelengths and more energy. These high-energy, short-wavelength blue light rays are sometimes referred to as blue-violet or violet light. As 21st Century workers, watchers and producers, we spend a lot of time in front of digital screens, meaning we are exposed to a significant amount of blue light being emitted from our devices.
But what exactly does that mean? Well, according to the latest research, extreme and sustained exposure to blue light may cause damage to your eyes, but it isn’t the only concern.
Is Blue Light Bad For You?
While research has indicated that extreme exposure to blue light isn’t exactly good for your health, you don’t have to throw out your smartphone or tablet just yet. There is no evidence to suggest that being subjected to blue light in small doses will have any lasting effects. Instead, you may encounter short term issues as a result of blue light. Here are three of the most commonly reported side effects of blue light exposure.
One of the major issues that people report is eye strain. Going hand in hand with technology use, you can often spend too much time focusing on small objects and digital screens. This can lead to dry or itchy eyes, loss of focus, headaches, fatigue and even neck pain.
Blue light can be a tricky beast and a confusing phenomenon for our bodies to understand. The most common issue related to blue light exposure is interrupted sleep. As we get most of our blue light rays from sunlight, using technology long into the night can trick our brains into thinking it is still daytime. These blue wavelengths disrupt our bodies’ circadian rhythm, telling our biological clocks to stay awake and wait for the darkness.
Further, blue wavelengths are known to enhance mood and increase energy, so using your phone or tablet immediately before bed may make it hard for you to relax and get to sleep. All colours of light may suppress the release of melatonin, our body’s natural sleep hormone, but studies indicate that blue light is particularly disruptive to our sleeping patterns.
As we mentioned above, prolonged extreme exposure to blue light may have dire consequences for your eye health, possibly leading to macular degeneration. This could mean incurable damage to your vision and the potential for blindness, however, the studies are not conclusive.
Simple Guide to Blue Light Protection
While there are a wealth of ways you can protect yourself from blue light, it’s important to remember the easiest way to stay healthy is to tune out. Avoid using digital devices in the hours closest to bedtime in order to let your body adjust to the lack of white light.
If you find yourself suffering the effects of blue light during the day, either from working too hard or spending too much time playing Animal Crossing, one method for protection is fitting yourself with blue light blocking glasses.
What Are Blue Light Blocking Glasses?
Blue light blocking glasses are essentially glasses fitted with a specially designed film that is constructed to adjust the light emitted by our devices from cool to warm. Blue light blocking glasses are one of the easiest and best ways to filter blue light and are ideal for anyone who spends the bulk of their time fixated on a screen. The film can be added to your sunglasses, prescription glasses or to frames with a clear lens. The blue light blocking film is clear, so it won’t significantly alter your vision as you look through your glasses.
How Do Blue Light Glasses Work?
The lens tint technology, while clear, filters out the highest energy and shortest wavelength light rays. Yes, those pesky blue light rays are blocked before they reach your eyes. By absorbing the blue-violet light from our devices and lighting, the lens film may potentially help you to avoid headaches, eye strains and interrupted sleep, regulating your body and keeping your health in check.
The Best Blue Light Blocking Glasses
It seems like every optical brand is jumping on the blue light glasses trend at the moment, and for good reason. The film is easy to produce and can be fitted over essentially any frame shape you can think of. In fact, many of the brands you know and love have offered blue light blocking glasses for years, you just may have never noticed what they were. Here in Australia, there are a bunch of local operators muscling into the market.
We’ve picked our favourites, from home and abroad in this list of the best blue light blocking glasses to save your eyes.
1. Pacifico Optical – Buckler
Australian sunglasses brand Pacifico Optical is born in Bondi Beach. These particular frames are named after the iconic north headland, Ben Buckler Point. A classic unisex round frame shape, we love the champagne finish although practically every frame from this company can be switched to a blue light protective lens with their Made to Order range. Each set comes with Blue Light Blocking lens, carry case, microfiber cloth, maintenance and cleaning kit.
2. BARNER Blue Light Glasses
We’ve been using the BARNER blue light glasses for months as they were the first pair to jump on our radar with a classic round tortoiseshell design. As we move between home and the office in a hybrid working environment these glasses are our new best friend – working in front of an open window at home means our monitor has to run at full brightness all day and headaches and bloodshot eyes were a regular occurrence. We’re pleased to say the CR39 lenses do a great job at blocking 100% of the Blue Light under 410nm (45% of the Blue Light on the 410nm – 450nm spectrum) and our eyes are no longer strained from sitting in front of a bright monitor. The fit is more than comfortable for all-day wear and the rubberised texture provides ample grip on our nose and ears. Priced at $95 USD these are a great budget option.
