Relax Swannies: Soft yellow lenses for after work that gently reduce blue light to help your body wind down while keeping your environment feeling natural and connected.

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

Focus lenses filter harsh high-energy visible light while maintaining clear, natural colour perception. Ideal for work, screens, travel, and everyday productivity.

Transition out of work mode

Relax lenses reduce stimulating short-wavelength blue light while preserving colour accuracy and visibility. Perfect for evening screen use, socializing, and post-work wind-down.

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.

Protect your melatonin before bed

Sleep lenses block virtually all melatonin-disrupting blue light between 400–500nm, helping your body prepare for deeper, more restorative sleep

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.
