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.
The lenses in Night Swannies were found to be among the top performers in lenses that block sleep-disrupting light, in a study conducted by the University of Arizona.
Dr Michael Grandner, Director of the University's Sleep and Health Research Program tested 50 lenses from a variety of brands for their effectiveness in blocking short-wavelength light that suppresses natural melatonin production.
For best results, wear them 1-2 hours before bedtime while using any electronic devices or under artificial lighting.
The orange tint will alter color perception somewhat, but most users adjust quickly. The trade-off of better sleep is well worth it!
We recommend our fit-over styles for prescription glasses wearers, or consider our custom prescription Night Swannies.
Digital filters only reduce blue light by 10-20%, while Night Swannies block 99-100% of harmful wavelengths. Plus, Swannies protect you from all sources of blue light, not just your screen.
