Calculation of ocular lighting according to the user, device used, use distance and pupil diameter
It is based on the premise that LED screens emit light with a high proportion of short wavelength, which can produce damage to the eyes and to other structures of the body.
METHODOLOGY: The emissions of LED screens of different marketed devices were measured and the amount of high energy light that reaches the eye was calculated for different pupil diameters.
-The amount of light that reaches the eye when they use a smartphone is 7 times higher than when they use a computer.
-Children receive 3 times more light than an adult who uses the same device, due to the shortest distance of use.
