Blue Light: is there a risk of harm
The human eyes are sensitive to a narrow band of light wavelengths that range from blue (short wavelength and high energy) to red (long wavelength and lower energy). Blue light makes up approximately one third of the visible spectrum. The sun is our main and natural source of blue light. However, with advances in technology, we are also being exposed to other sources of blue light such as computer monitors, smartphone screens, flat screen televisions and LED lights.
