Sleep Swannies Blue-Banned Black

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.

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.

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.

Swannies Blue Light Blocking Glasses are FDA registered and have been extensively researched, designed, and manufactured specifically to block the full spectrum blue light by combining a specific colored tint with special AR coatings which work together to effectively filter blue light.

Sleep Swannies are made with high-quality acetate or alloy frames featuring spring hinges and top of the line CR-39 lenses with UV rated anti-glare coating on both front and back. We are confident that you won't find better quality blue light blocking glasses on the market!

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.
