Hear it from the experts.

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.

The Swannies blue glasses improved both sleep and work outcomes.

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.

Another brand that’s highly rated is Swanwick, known for blocking blue light exposure.

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.

Swannies are hugely popular and pretty affordable blue light blocking computer glasses...

  • Night Swannies (orange lens) block more than 99% of blue light between 400-500nm and are designed for wearing before bed time. This is because blue light from 450-480nm has been shown to prevent the body from naturally producing melatonin.

    At night time, blue light exposure should be limited as much as possible so that your body can get ready for sleep.

    Day Swannies (clear lens) are designed specifically for wearing while using screens during the daytime. They block 45-98% of blue light in what studies have found to be the most harmful part of the blue light spectrum between 400-450nm.

    Day Swannies allow a natural level of exposure between 450-500nm, giving your body the signals it needs to stay awake during the daytime and allow you to perform at your best.

    A natural level of blue light during daytime boosts alertness, memory and brain function. Day Swannies afford these benefits while protecting against harmful rays from computer screens etc., which can lead to digital eye strain.

    When you combine a healthy level of blue light during the day and limit your exposure to all blue light at night, this will help regulate your sleep/wake cycle to help you optimize both your sleep and waking hours.

    For those who need corrective lenses, we offer several options.
