Can I wear Day Swannies at Night?

While you can wear Day Swannies at night, they will not help with sleep, as they do not block the specific wavelengths that have been shown to suppress melatonin. This is because during the day, we want to allow some of this blue light in, as this actually helps keep you awake and alert during daytime hours.

Day Swannies will continue to protect you from the symptoms of eye strain at any time of day, but please bear in mind if you are looking to optimize your sleep, the Night Swannies will be your best option as they block over 99% of all blue light; something that can only be done with tinted lenses.
