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

Part of the Swanwick Circadian System

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 Sleep Swannies blue light blocking glasses.

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.

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.
