Information for blue light
Blue light wave is one of the shortest, highest-energy wavelength that's between approximately 380nm-500nm in visible light spectrum. And Blue light is actually everywhere.
Natural blue light vs.Artificial blue light
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).
Artificial sources of blue light include digital screens (TVs, computers, laptops, smart phones and tablets), electronic devices, and fluorescent and LED lighting.
Why should we protect our eyes from blue light exposure?
Because blue light waves can penetrate lens and directly reach retina. Prolonged exposure may cause eye strain, dry eyes, headache, difficulty sleeping, and even damage our retina photochemically and increase the risk of macular degeneration over time.
