Blue light illuminates our homes, offices, streets, and the devices we count on every day. But what's behind this light that's causing such a commotion?
Blue light is a range of light that contains the highest amount of energy in the visible light spectrum. Light wavelengths are measured in nanometers (nm). Blue light resides in the range from 400-500nm.
Historically, we got our daily diet of blue light from the sun. But times have changed and so has the way we light our world. These days blue light is beaming at us from all directions.
