Blue light: Is it worth blocking?04/07/2020
What is blue light? Blue light can be found in anything from fluorescent lighting to LED computer screens, including the cell phones you use every day. When our eyes are exposed to blue light, excitatory signals are sent to the brain. It’s essentially sending the message “Wake up and smell the coffee!”. Daylight consists of non-visible, harmful UV light, and visible “beneficial” light. Blue light is found where these two spectrums meet and is referred to as HEV light or high energy visible light (see image).
