Scientifically Tested and Validated
Night Swannies® are the only blue light blocking glasses to have been independently and scientifically validated by several studies.
Journal of Applied Psychology
A 2020 study by the University of Washington and Indiana University was published in the Journal of Applied Psychology and featured in the Harvard Business Review. The study found that workers who wore Night Swannies® Blue Light Blocking Glasses in the evening before bed, significantly improved the quality and quantity of their sleep, along with their effectiveness at work the next day.

-
11 minute decrease in time spent falling asleep
-
24 minute decrease in time spent awake during the night
-
37% increase in feeling rested in the morning
-
14% increase in time spent in deep sleep
-
14% increase in average daily sleep quality
