Description

Looking for the simplest way to take control of your sleep, energy, and focus?

The Circadian Snap-On Set is a complete light management system designed to support your body’s natural rhythm in a world of screens and artificial lighting, without adding more tech to your performance stack.

Built around an almost-clear Focus base pair, the system includes two precision magnetic snap-on lenses: Relax to help you unwind in the evening, and Sleep for powerful nighttime melatonin protection. Instantly adapt to your environment by switching lenses throughout the day, supporting sharper focus, calmer evenings, and deeper, more restorative sleep.

No apps. No supplements. No changing your routine. Just one pair, three lenses, and full control over your light exposure from morning to night.

Blue-banned Swannies feature a bold rectangular silhouette crafted from premium acetate, inspired by the iconic Wayfarer style. Lightweight and comfortable for all-day wear, this flexible, durable unisex frame offers a modern oversized fit that remains timeless. Includes our innovative magnetic Circadian Snap-On lens system.

Premium foldable case is included.

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, switch to 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.

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.
