How to wear Night Swannies for sleep

To optimize your sleep, Night Swannies should be worn at least 1-2 hours before bedtime continuously.
Try not to take them off at all until you have turned off all lights and devices and are already in bed ready to sleep.
Some people find better results from wearing them even earlier and we encourage you to experiment to find what works for you.

How to wear Night Swannies for blue light protection

Night Swannies can also be used during the day to protect your eyes from excessive blue light exposure, eg. when using digital devices for prolonged periods.
We do not recommend you wear Night Swannies continuously for the whole day.
If you want extended protection during the daytime, we recommend our Day Swannies collections, which can be worn continuously all day.

How Swanwick® blue-light blocking lenses improve your sleep

Swanwick has spent over six years testing and developing its lenses to give the best results for sleep optimization and wearing experience.

Classic Night Lenses

Calming Effect

Too much artificial blue light can result in feeling ‘wired’ and increase feelings of anxiety in the evening. Turn off the ‘noise’ by wearing your Night Swannies blue light blocking glasses in the hours before bedtime and you’ll immediately feel more relaxed.

Kick-start your sleep clock

Wearing Swannies blue light blocking glasses before bed gives your body’s natural clock the signals it needs to prepare for sleep. This includes naturally producing melatonin, the sleep-promoting hormone. Blue light is everywhere and it can't be avoided. Wear blue light glasses like Swannies to battle the blue light beast.

An investment in your overall health

Sleeping well is as important to your physical and mental health as eating right. Long term sleep deprivation is linked to a host of health problems such as obesity, diabetes, heart disease and even shortened life expectancy. Get healthy by sleeping well using Night Swannies blue light blocking glasses.

Quality sleep

Once you’re asleep, the blue light you were exposed to before bed can continue to wreak havoc on your sleeping pattern. Get deeper and more restful sleep by using Night Swannies blue light blocking glasses continuously before bedtime.

Eye protection

Working at night? Night Swannies blue light blocking glasses protect your eyes from the blue light that can cause digital eye strain, leading to headaches, sore, dry eyes and reduced productivity.

Why Swanwick?

Swanwick is the only brand of blue light blockers that have routinely sought third party validation. We've been studied by the University of Washington and the University of Indiana. We've been featured in a study by SleepScore Labs, and had research findings published in the Journal of Applied Psychology and Harvard Business Review.

There is no other brand on the market that has gone to the lengths we have to make the validation of our technology the backbone of our company. Talk is cheap in the blue light world. Why Swanwick? Because our actions speak way louder than their words.
