Our circadian rhythm is governed by the alternation of light intensity during the day and night. White daylight (blue and green spectrum) gives the body information that it is time to be awake, its decrease prepares us for rest. The bluish lights of television screens, computers or phones in the evening disrupt our biological clock and thus the natural production of melatonin before bedtime . Dayzen Red glasses against blue and green light are intended for evening wear, because they filter the green and blue spectral components very well. They are effective even when the light is really strong. Thanks to their special design, light does not enter the eyes from any side, the eyes are perfectly protected .
