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...

Our Swannies with 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.
We have several options for those who wear glasses. Firstly we have our Fitover Swannies, which are specially designed to be worn over another pair of glasses. These are available in both Day and Night lens, or as a value Bundle: https://www.swanwicksleep.com/collections/fitovers.
Secondly, you have the option of ordering custom prescription Swannies from us. This is where we make our Day or Night Swannies with your own prescription in the lens. These lenses are made to order in our lens lab in California. You can view our prescription options at the following link: https://www.swanwicksleep.com/collections/prescription-swannies.
Swannies Day Glasses should be worn any time you are using devices with digital screens during daylight hours. This will allow you to block the most harmful part of the blue light spectrum (between 400-450nm) whilst allowing natural levels of beneficial blue light through, which will help you to regulate your sleep/wake cycle.
When the sun goes down, you need to block more of the blue light spectrum, to signal to your body that it’s time to get ready for sleep. For this, we recommend switching to our orange tinted Swannies Night Glasses, which are designed to block the full spectrum of blue light, including the wavelength shown to suppress melatonin production (450-480nm).
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. You can access our full reports below:
Night Swannies block over 99% of blue light between 400-500nm, and around 80% of green light from 400-550nm.
Day Swannies block 98% of blue light at 400 nanometers, graduating to 45% at 450nm (the most harmful part of the spectrum). Day Swannies also block between 21-45% of blue light between 450-500 nanometers.

Because short-wavelength, high energy blue light scatters more easily than other visible light, it is not as easy for the eye to focus on. Additionally, artificial blue light emitted from devices exposes your eyes to unnatural levels of blue light which have the ability to cause long term damage to your eyes. This means that when you're looking at computer screens and other digital devices, this unfocused visual "noise" and unnatural levels of blue light contribute to digital eye strain. Symptoms of digital eye strain include dry, sore eyes, discomfort and headaches.
Day Swannies filter the unnatural levels of high energy blue light below 450nm to allow your eyes to focus more easily for longer periods of time. By reducing the strain and harmful blue light your eyes are exposed to, you can focus on your work for longer, without incurring negative effects related to digital eye strain.
In addition, research has also shown that a healthy level of blue light can help with memory and alertness, encourage serotonin production - all things that will help to boost your productivity during daylight hours. This is why Day Swannies still allow a natural level of blue light to filter through so you can get the best of both worlds.

How Day Swannies® Blue Light Blocking Glasses Tackle Eye Care and Improve Productivity
With over six years of research and development, Swanwick Blue Light Blocking Glasses have been specifically designed to solve the problems of working in a digital world. Here’s how we accomplish this.
Block more blue light than other glasses
Day Swannies block more blue light in the harmful part of the blue light spectrum (400-450nm) than most clear blue blockers on the market. Our transmission reports are fully published on our website for transparency.
Headaches no more
Headaches are one of the main symptoms of Digital Eye Strain. By wearing Day Swannies, you can reduce the occurrence of symptoms such as blue light induced headaches.
Shield your eyes from blue light
Specially selected lenses and scientifically developed lens coatings are expertly combined to block the right amount of blue light. Lenses are lab tested for blue blocking effectiveness.
Improve your productivity
Long hours working on screens can take their toll, resulting in reduced productivity due to digital eye strain. Work smarter and let Day Swannies take the strain out of your work day so you can work longer without the negative side-effects.
Prevent tired eyes from screens
Glare and screen flicker from digital devices cause your eyes to work harder, resulting in them feeling tired after prolonged periods. Swannies lenses reduce these negative effects from screen exposure to help your eyes from feeling fatigued.
Benefit from good blue light
Not all blue light is bad during the day. Your body needs some blue light exposure to help regulate your circadian rhythm, and blue light has also been shown to help improve cognitive function, memory and alertness. Day Swannies let in a natural level of the good blue light so you get all the benefits without the downsides.
