Our Night Swannies lens technology blocks over 99% of blue light between 400-500nm – the perfect range for promoting optimal sleep conditions – so you can get to sleep quickly and effortlessly.

A 2020 study by the University of Washington and Indiana University 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.

In the week they wore Night Swannies, workers:

• Slept 6% longer
• Improved the Quality of their sleep by 14%
• Improved their Task Performance by 9%
• Increased their Work Engagement by 8.5%

And remember, digital eye strain during the day can occur when engaging with screens all day long. This strain can be alleviated with our Fitover Day Swannies that feature our proprietary daytime bluelight protection that allows good spectrums through but not the harmful ones. Protect yourself from morning to night with our Fitover Day and Night Swannies Bundle.
