What is blue-violet light?
Both inside and outside, harmful blue-violet light is all around us, emitted by digital devices, LED artificial lighting, as well as by the sun.
While being outdoors during daylight hours has traditionally been the main source of blue light exposure for most us, our increasing reliance on technology means we are also now exposed to many man-made indoor sources of blue light.
If you spend more than 2 hours a day staring at a screen (whether its a smartphone, tablet or computer), use LED lighting, or you work outdoors, harmful blue-violet light can be doing both short- and long-term damage to your eyes.
