Rejection describes the ratio of the transmitted radiant or luminous flux to be cut off when the incident light passes through a sample .
In optics and spectroscopy, transmittance is the fraction of incident light at a specified wavelength that passes through a sample. Transmittance is measured in percent and is used to specify the light throughput of transparent materials.
Harmful Effects: The retina of the human eye does not handle blue light well. Doctor Sliney states that blue light sends an extremely intense signal to the muscles of the eye telling them to shut down. It can cause severe
