Day Swannies® blue-light blocking glasses are essential for productivity and eye care

The result of extensive research and development, Swannies Blue Light Blocking Glasses were created to solve the pain points of working in a digital environment. This is how we do it.

Classic Day Lenses

Block more blue light than other glasses

Most clear lens blue blockers block very little blue light over 420nm. Day Swannies block more blue light in the harmful part of the spectrum up to and over 450nm. Our full transmission reports are available on our website.

No more headaches

Prolonged exposure to blue light can cause unwanted headaches. Reduce Digital Eye Strain symptoms such as headaches by wearing Day Swannies during screen time.

Best blue light blocking technology

Specially designed lens coatings are combined with proprietary lenses to block the right amount of blue light for daytime. Laboratory tested for effectiveness and quality.

Optimized productivity

Digital eye strain resulting from working on screens for prolonged periods can lower productivity over time. Day Swannies help you work smarter and longer by alleviating the effects of screen time, so you can continue to be productive all day, every day.

Stop fatigued eyes from screen time

The flicker and glare from digital screens make your eyes work harder than normal. This causes eye fatigue and tiredness. Day Swannies counteract these negative effects caused by screen exposure, reducing eye fatigue.

Utilize the good blue light

Some blue light is good for you in the daytime. Your body relies on natural blue light to regulate circadian rhythm, and blue light can contribute to memory, cognitive function and alertness. Day Swannies allow natural levels of good blue light above 450nm to pass, so you don’t miss out on these benefits, while remaining protected.

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.
