It may not be something we consciously realise, but light is everywhere, and each source of light is different even if we can’t see it with the naked eye. If you look at a light spectrum wheel, you’ll see that sunlight rays are mostly red, orange, yellow, green and blue rays that are commonly called ultraviolet (UV) rays.
The blue light element of sunlight is what is utilised in many indoor light sources, including LED technology, many TV’s and fluorescent lighting. This mean that your computer or laptop screen, smartphone or similar device also feature blue light technology. In short, when you’re looking at your phone, your eyes are adjusting to the same light as in sunlight - albeit, a very small fraction.
Once you understand the physics behind blue lights, you can begin to see why medical experts have become extremely concerned with just how dangerous blue light exposure is to today’s tech users.
The human eye is truly incredible. Perfectly engineered to not only provide us with our vision but to protect us against potential eye dangers, the retina is the most light-sensitive part that needs the most protecting. Our eyes can naturally block many UV rays from getting through to the retina, however almost all blue light reaches the retina. This spells disaster.
With so many of us glued to our phones, computers or televisions at all times of the day, the blue light we are exposing ourselves to increases the risk of eye damage and adds “digital eye strain.” Macular degeneration is a common result of overexposure to blue light rays, which can lead to permanent blindness.
We aren’t suggesting you wear your favourite shades every time you flip open your laptop or scroll through your phone - although good-quality sunnies do offer fully protect against blue light dangers!
