Not all blue light is bad - some exposure is good for our health.
Sunlight is the main source of blue light but there are also man-made sources. Fluorescent and LED lighting, flat-screen televisions, computers, smartphones and other digital devices all emit amounts of blue light. The amount of blue light from these devices is small compared to levels from sunlight.
Exposure to blue light from the sun during the day is good for us, helping us to stay alert, perform well and stay in a good mood.
With people spending increasing amounts of time on digital devices, this raises concern about possible long-term effects of blue light over-exposure on eye health. Exposure to blue light from these artificial sources can disrupt the internal body clock, particularly in the evenings – tricking our brains into thinking it’s still daytime, with potential to disrupt sleeping.
It does this by inhibiting the natural production of melatonin, a hormone in our bodies that regulates sleep.
Studies have shown that wearing blue light blocking lenses when you use digital devices will reduce this effect.
Over-exposure to artificially made blue light (even during the day) can also contribute to headaches & migraines, and dry or fatigued eyes leading to blurred vision and discomfort. This collection of symptoms is becoming known globally as Digital Eye Strain, or Computer Vision Syndrome.
We have a solution. Avatude Blue Light Eyewear combines comfortable & stylish frames with quality UV400 and UV420 blue light blocking lenses to reduce digital eye strain. These are perfect for people who do not use prescription glasses.
