The junk light epidemic

Can’t relax? The problem is staring you in the face

History

For 99.99% of human existence, blue light was only present during the day. The sun went down, blue light faded, and our body knew it was time to sleep.

Fast forward

Now, blue light is everywhere. Screens and artificial lighting expose us to junk light long after sunset, tricking the brain into thinking it’s still daytime.

Why this matters

This delays melatonin production and keeps the nervous system alert at unnatural hours – leaving us feeling wired instead of tired.

Prescription Circadian Swannies Snap-On Blue-Banned Black FAQ

How Swannies® redefine blue light protection

Most blue light glasses rely on basic coatings that filter only a small portion of blue light and are rarely validated for real-world performance.

Swannies® are different. Our lenses are precision-engineered to target specific wavelengths that influence focus, relaxation, and sleep. Each lens is third-party tested and designed with a clear purpose within your circadian rhythm, delivering effective blue light reduction without unnecessary color distortion or compromise.

The result is a more intentional, performance-driven approach to light management, not just a tinted lens, but a system designed to support how you function and recover throughout the day.

Will they actually improve my focus or just reduce eye strain?

By reducing harsh blue light exposure, Focus Swannies® help minimize visual fatigue, headaches, and screen-induced strain. This allows you to stay mentally sharp, focused longer, and more comfortable during extended screen use.

What problem do Relax Swannies® actually solve?

Modern environments keep your brain in a constant state of stimulation. Relax Swannies® reduce the intensity of artificial light and blue light exposure, helping your body shift out of high-alert mode so you can feel calmer, less wired, and more at ease.

Do sleep glasses work? How they help improve your sleep quality

Independent scientific studies have shown that wearing Swannies improves sleep and helps you perform better the next day. Research shows that blue light between 400 and 450nm can cause retina damage and that blue light between 450 and 480nm suppresses the production of melatonin, the hormone essential to quality sleep. By blocking this spectrum of light, Sleep Swannies help your body easily slip into the natural circadian rhythm that unnatural light sources like smartphones and TVs interrupt.

When shopping for blue light blocking glasses, it’s essential to find the details about not just what range of the light spectrum they block, but what percentage of blue light they block. Not all glasses that claim to block blue light are able to do so to the same degree.

Sleep Swannies block over 99% of blue light between 400-500nm (as tested by a third-party laboratory), ensuring you the optimal conditions for falling asleep quickly and more deeply.

Why can’t I just dim the lights or use night mode?

Even dim indoor lighting and screens still emit enough blue light to disrupt your circadian rhythm. Sleep Swannies® provide complete protection regardless of your environment, making them far more effective.

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.
