In our digital age, we are surrounded by screens and artificial light. We are more reliant on our computers, smart phones, tablets and electronic reading devices than ever before. Traditionally printed material like books, newspapers, advertising brochures are jumping on the electronic bandwagon and we are reading, learning, working, watching and playing on digital devices regularly.
You may have heard or read about blue light blocking computer glasses and you may be wondering if these actually work and whether you need them. We have done the research for you, so read on for more information on blue light and the blue light blocking recommendations by The American Optometric Association and Harvard Medical School.
What Is Blue Light?
The light that we see is radiation which is part of the electromagnetic spectrum. Visible light comprises of red, orange, yellow, green, blue, indigo and violet light. Of which, blue light is the most notorious for causing optical degeneration and sleep disturbances. Blue light carries more energy than lights on the other end of the spectrum which gives it the most potential to cause harm.
Where Is Blue Light Found?
Blue light is found wherever there is light (including light from the sun and indoor lighting), and light that appears white to you contains the highest density of blue light. It is not surprising then that digital screens 0f computers, smart phones, tablets and televisions cause the most harm. According to market intelligence reports by The Nielsen Company, Americans spend up to 12 hours each day of leisure time on their screens1! Now add in the time spent looking at screens at the workplace and that will give you an idea of the invasiveness of blue light in your life.
How Does Blue Light Affect You?
Staring at computer and smart phone screens at a close distance for prolonged periods of time results in the following:
1. Digital Eye Strain or Computer Vision Syndrome (CVS)
Do you have eye discomfort, dry eyes, headaches, blurred vision or neck pain while working on your digital devices? If yes, you might be suffering from digital eye strain or computer vision syndrome. This is caused by the need for your eyes to work harder when using a screen. The American Optometric Association recommends using special computer glasses to protect your eyes and to reduce the strain required to handle the visual demands of viewing a screen2.
2. Sleep Disturbances
Blue light has been shown to disrupt the production of melatonin which is often referred to as the "sleep hormone". A Harvard study has found that this reduction in melatonin production due to the exposure to blue light resulted in shifts in people's circadian rhythm (in other words, our "sleep-wake" cycle). This in turn results in poor sleep which has been linked to increased health risks such as depression, diabetes and heart problems. The Harvard Medical School thus recommends the use of blue light blocking glasses to improve sleep3. As blue light is not only emitted from digital screens, the use of such glasses are also recommended for people who work the night shift and are exposed to artificial light at night.
3. Macular (Eye) Degeneration
The high energy carried by blue light enters the eyes and damages the cornea (which is the outermost transparent flap that covers your iris and pupil), through to the lens, and all the way to the retina (the innermost tissue of the eye). This damage can then result in diseases including dry eye, cataract and macular degeneration. R
Blue Light Blocking Computer Glasses for Eye Protection and Health
As our use of digital devices increases at work, at home, and at play, the glaring ill-effects of blue light emitted from our screens can no longer be ignored. Computer glasses that filter out blue light by absorbing and reflecting the blue light waves away from your eyes can help to minimise the glare from screens and can allow you to view them comfortably whilst minimising your health risks. Despite its name, computer glasses are not solely designed for using the computer. Their blue-light filtering abilities also help to optimise your vision and protect your eyes from the blue light emitted from the sun and indoor artificial lighting.
Blue light blocking computer glasses are ideal for you if you:
- Spend prolonged time on the computer for work or for lesiure
- Rely heavily on your mobile phone or tablet
- Use your digital devices at night
- Experience eye strain, headaches, blurred vision, neck and shoulder pains during or after using the computer
- Work night shifts
- Have disturbed sleep
- Are worried about eye degeneration from prolonged viewing of screens
Will Blue Light Blocking Glasses Affect My Vision?
A good quality blue light blocking lens will appear reflective and when you look through them, you will notice an orange tint. Although your perception of colour is different, it is perfectly normal. Think about the visible light spectrum of red, orange, yellow, green, blue, indigo and violet light that forms the "white" light that we see. When your glasses absorb and reflect away the blue light, what you see will naturally veer closer to the other colours. Hence, it is normal for you to notice that your surroundings and screens are more yellow or orange than you are used to.
Getting A Good Pair of Computer Glasses
Glasses are like an extension of our personality and how we portray ourselves to the world. They should be practical in helping to correct our vision and to protect our eyes, and they should also be fun, comfortable and stylish. Do you prefer the classic, sturdy feel of a metal pair? Or do you fancy a more trendy plastic frame? Or maybe you hate wearing glasses because of the heaviness on your face, placing unwanted strain on your nose and ears? Regardless, we have you covered with our metal, plastic, and TR90 frames! The TR90 frames have gained popularity in South Korea for its featherlight yet impact-resistant properties.
