What is Blue Light?
Within the visible light spectrum- there are different wavelengths of light. Purple and blue are among the highest forms of energy produced by light which is measured in what is called, nanometers. While blue light does come from the sun, the blue light that is given off by our electronic devices becomes a constant source of high energy light- similar to the glare of being in a pool with no sunglasses on. This type of light exposure causes the eye to strain which can have long-term negative effects on anyone's health, from babies to grown adults.
