How the Swanwick® Circadian System helps you perform, unwind, and sleep

The Circadian Snap-On Set gives you three lens options in one complete system. Start your day with Focus lenses for clarity and productivity, snap on the Relax lens when it's time to wind down, and swap to the Sleep lens to protect melatonin before bed. Designed to work with your body's natural circadian rhythms, it's the easiest way to optimize your light exposure from morning to night.

Focus when it matters most

Built around your body clock

Most blue-light glasses solve only one problem. The Circadian System supports your entire daily rhythm, helping you stay alert during the day, relaxed in the evening, and ready for sleep at night.

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.
