Blue Light Spectrum

In another study of blue light researchers at the university of toronto compared the melatonin levels of people exposed to bright indoor light who were wearing blue light blocking goggles to people exposed to regular dim light without wearing. The visible light spectrum spans from violet blue light which have short wavelengths ranging from 400 500 nanometers to red light which has the longest visible wavelength of around 700 nanometers. Blue led light or short wavelength light is a type of high energy visible light defined as having a wavelength between 400 and 450 nm.
