The CODE RED Bundle

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:

Night Swannies® should be worn continuously for 1-2 hours before bedtime. Some people find better results wearing them for even longer, such as as soon as the sun goes down. We recommend you experiment with what works best for you.

Ensure you wear your Night Swannies® continuously without taking them off until you are in bed with all the lights off. Once all lights and devices are off and you are ready to sleep, you can take off your Swannies®. This is because even a small exposure to blue light during this critical phase could cause disruption to your sleep.

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:
