What is Blue light?
All light we see is made up of different wavelengths of energy. Certain wavelengths show different colours. Each colour has a unique energy and wavelength, with longer wavelengths for red and shorter wavelengths for blue. The shorter the wavelength, the more energy it transmits.
Blue light, also known as high energy visible (HEV) light has very short wavelengths and transmits high energy waves.
Wavelengths of light are measured in nanometers (nm). Blue light (HEV light) wavelengths are between 400 and 450 nm. Most of the light from LEDs used in smartphones, computers, TVs, and tablets have wavelengths between 400 and 490 nanometers.
Studies have shown these high energy waves have the ability to penetrate the retina in the eye and can cause eye damage over time.
Blooies block over 53% of blue light over the whole 400-500nm spectrum giving you maximum protection.
