What is Blue Light?
Blue Light is a color in the ‘visible light spectrum’ that can be seen by the human eye. Blue light has a very short wavelength, between 380 nanometers (nm) and 500 nm, and so produces a higher amount of energy.
Blue light between 415 nm and 455 nm is harmful for the eyes. However, it is well documented that some blue light exposure is essential for good health. Research has shown that high-energy visible light boosts alertness, helps memory and cognitive function and elevates mood.
