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...

  • Eco-acetate frames Swanwick Eco-acetate is majority composed of Biobased Carbon derived from natural materials.
    Safe from chemicals Testing shows less than 0.01% detection of all Phthalates and hazardous substances under the RoHS Directive.
    Biodegradable material Biodegradability testing of Swanwick Eco-acetate shows 55.8% biodegradation in the first 150 days under controlled composting conditions.
    Proven Results An Independent study by Sleepscore Labs showed wearing Night Swannies significantly improved sleep, including an average 33% increased sleepiness at bedtime and 11 mins less time to fall asleep. A study conducted by University of Washington and Indiana University showed wearing Night Swannies improved sleep length and quality, resulting in a 9% increased task performance the following day.

  • Night Swannies with the orange tinted lens block 99.5-100% of blue light between 400-500nm and are designed primarily for wearing in the hours before bedtime, to improve sleep and prevent blue light related sleep problems. This is because blue light between 450-480nm has been shown to suppress the production of melatonin, the sleep-promoting hormone.

    At night time, blue light exposure should be limited as much as possible in order to align with the sun going down, which your body uses as the signals to prepare for sleep.

    The Day Swannies with almost-clear lens are specifically designed for screen-time during the day. They block between 45-98% of blue light between 400-450nm, which studies are have shown is the most harmful part of the blue light spectrum. They allow some of the blue light between 450-500nm to get through, because blue light exposure during the day important to give your body the signals that it is daytime and that it should be awake. Natural levels of blue light during the daytime can also help with alertness, memory and cognitive function. The Day Glasses give you these benefits while protecting your eyes from the harmful blue light.

    By allowing exposure to the good blue light during the day, and limiting all blue light at night, your body will get the appropriate signals to help regulate its sleep/wake cycle and help you get the best out of both your sleeping and waking hours.

    Here at Swanwick, we regularly have our Day and Night Swannies lens transmission independently lab tested by Colts Laboratories. We believe in transparency when it comes to the science behind our Swannies Blue Light Blocking Glasses. That is why, when choosing where to purchase blue light blocking glasses, we recommend you check whether transmission reports from an independent testing facility are available.

How Havana Day & Night Swannies protect your eyes and improve your sleep.

For over six years, Swanwick® has researched and developed the best lenses for blue light protection, sleep enhancement and wearing experience.

Improved Sleep

Night Swannies® block over 99% of blue light and are the most scientifically validated blue blockers that have been independently proven to improve sleep and subsequently enhance performance the following day.

Block more blue light than other glasses

Most clear blue blockers block little blue light above 420nm. Day Swannies block a higher percentage of blue light in the harmful portion of the blue light spectrum (400-450nm). We publish our transmission data for all of our lenses.

Circadian Rhythm Optimized

Give your natural body clock the right signals to get ready for sleep. With these proper signals, your body will produce its own melatonin, the sleep-promoting hormone, just like nature intended. Blue light can cause your sleep to be disrupted and of low quality. Sleep deeper and more restfully by wearing Night Swannies continuously before bedtime.

Shield your eyes from blue light

Prescription grade CR-39 lenses are combined with special blue light reflecting coatings to block the right amount of blue light for day or night use, all while providing superior optical clarity.

Quality sleep

Blue light can cause your sleep to be disrupted and of low quality. Sleep deeper and more restfully by wearing Night Swannies continuously before bedtime.

Prevent tired eyes from screens

Digital screens create glare and light flicker which make your eyes work harder, causing a feeling of fatigue and strain after prolonged periods. Swannies lenses protect your eyes from these negative effects, helping you work longer without consequences.
