If you want to use your iPad, mobile phone or watch TV at night before bed, that turn off your brain’s ability to produce melatonin. Swannies [blue light glasses] filter out that blue light so that you don’t have to give up your devices.

I’m a believer in how Swannies blue light blocking glasses affect sleep onset and duration of sleep because we see it all the time with our patients and our athletes.

Swannies [blue light glasses] scored consistently well in all aspects that we tested. They have managed to combine effectiveness at filtering sleep-disturbing blue light while also allowing in non-sleep disrupting light, striking the right balance of sleep benefits.

We tested Swannies [blue light glasses] to determine if the glasses would improve an individual’s sleep quality and found that using Swannies significantly improved sleep and increased the amount of deep sleep, and ultimately supported a better night’s sleep amount participants.
