Digital devices and modern lighting such as LED lights and compact fluorescent lamps (CFL’s) emit a high level of blue light. CFL’s contain about 25% of harmful blue light and LED contain about 35% of harmful blue light.
The highest level of UV exposure is between 10 a.m. and 2 p.m. in the summer and from 8-10 a.m. and 2-4 p.m. in the winter.
It is estimated that by 2021, 90% of all of our light sources are estimated to be LED lighting. So our exposure to blue light is everywhere and only increasing!
