What is blue light? 
 Blue light wave is one of the shortest, highest-energy wavelength that's between approximately 380nm and 500nm in visible light spectrum. Natural blue light comes from the sun. Our body uses blue light from the sun to regulate our natural circadian rhythm (sleep and wake cycles), boost alertness, heighten reaction times, elevate moods, and increase the feeling of well being. Artificial sources of blue light include digital screens such as TVs, computers, smart phones, and fluorescent and LED lights. 
 Why Should We Protect Our Eyes from Blue Light? 
 Because blue light waves are one of the shortest, strongest energy wavelengths in visible light spectrum, they can penetrate lens and directly reach retina. Our eyes do not have sufficient natural filters to protect against blue lights. Prolonged exposure to blue light from digital screens or fluorescent / LED lights may cause eye strain, dry eyes, headache, difficulty sleeping, and even damage our retina photochemically and increase the risk of macular degeneration over time.
