The junk light epidemic

Can’t sleep? 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
Constant exposure can lead to digital eye strain, visual fatigue, and mental burnout - leaving you foggy, overstimulated, and less productive.
A modern solution
Focus Swannies® Blue Light Filtering technology reduces harsh artificial blue light from screens and LEDs - helping you stay comfortable and clear in bright digital environments.
Daily impact
The result? Your natural sleep rhythm is restored, helping your body recover and wake up properly rested.

Focus Swannies Readers Classic Tortoise 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.

Do I need these if I already use night shift or screen filters?

Screen settings only reduce a portion of blue light and vary by device. They don’t protect you from overhead lighting or your full environment. Swannies® provide consistent, full-spectrum light management across all your devices and surroundings, so you’re fully supported wherever you are.

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.
