Blue light is different to the other hues in that it has a shorter wavelength, meaning it reaches and affects our eyes quicker than other hues.
Blue light can be found in artificial forms such as that which is emmitted from mobile phones, televisions and computer screens, LED lighting and fluorescent light bulbs. These are the most widely recognized forms of blue light. However, blue light appears more in other areas of everyday life.
Our bodies operate on a circadian rhythm that flows with the earth’s rotation and causes us to wake up and go to sleep.
Blue light effects our sleep rhythm in that it lets the body know when it's time to go to sleep (when the sun goes down) or when it's time to wake up (when the sun rises and reintroduces blue light into the atmosphere).
Due to it's short wavelength, blue light tends to flicker easier than other hues such as red, orange, yellow and green. Our eyes don’t cope well with this flickering, causing the eye to fatigue easily as it is having to perceive a hue that is essentially turning on and off rather than consistently shining.
Other visible light hues do not flicker like blue light and this is what separates blue light from the rest and makes it much more hazardous to human eye health.
With more and more people working from home with an inevitable increase in screen time, there really is no escaping the effects of blue light.
Prolonged exposure to blue light rays causes immediate symptoms of eye strain such as dizziness, blurred vision, light headedness, dry and irritated eyes and difficulty focusing.
If that isn't damaging enough, long-term effects can include retinal damage and also be conducive to age-related macular degeneration and may eventually lead to loss of vision.
That’s why NuBlue, Blue Light Glasses were created!
We were born with a mission to share our knowledge with our fellow Australians about the harmful effects of blue light.
We want you to be able to go about your day without dealing with sore tired eyes or worrying about blue light ever again!
Approximately 63% of adults experience symptoms of digital eye strain after using a digital device for only 2 hours. These symptoms generally start with a small pressure build-up between the eyes that normally turns into a mild headache, and in extreme cases, digital eye strain can cause blurred vision.
Our kids are often using devices just as often or even more than us. While we can try to limit our exposure to digital devices, it is not always a practical solution as 8 out of 10 adults are required to use a computer at work and children are spending upwards of 6 hours per day on digital devices. This is when blue light blocking glasses come in as the most viable solution to limiting our exposure to blue light.
