Normal sunglasses aren’t engineered to filter out blue light. That’s why we created our Henley Sunnies sunglasses that block between 80-95% of all blue light between 400-500nm, which studies have shown is the most harmful part of the blue light spectrum.

During the day, some of the blue light spectrum (between 450-500nm) is important to get through your lenses, because this type of blue light exposure during the day is key for giving your body the signals that it is daytime and supposed to be awake.

Blue light during the daytime can also help with alertness, memory, and cognitive function. Henley Sunnies give you these benefits while protecting your eyes from the harmful spectrums of blue light.

For driving during the day when it’s sunny outside, Swannies Sunglasses are your best option. Beyond our blue light blocking technology, the lenses in our sunglasses are polarized to protect from glare and UVA/UVB rays while preserving color and visual clarity.

While all Swannies are 100% UV-rated and offer protection from UV rays, our day and night Swannies are primarily designed to be worn indoors and when using digital devices and do not offer as dark a tint as sunglasses, which are designed to reduce sun glare.

With our increasingly digital lives, there’s almost non-stop exposure to harmful artificial blue light. Fortunately, Swannies Day glasses and Henley Sunnies glasses can be worn all day, as they still allow plenty of the beneficial natural blue light rays to pass through while blocking the harmful spectrums of blue light.

Blue light blocking glasses are designed to increase productivity during your day by blocking harmful spectrums of blue light while letting beneficial blue light spectrums through. By letting the right blue light through, your body clock is regulated to stay alert throughout the day.

When worn during prolonged use of electronic devices, Henley Sunnies help prevent symptoms of digital eye strain such as sore eyes, headaches, and fatigue. By blocking this spectrum of light, Henley Sunnies help your body maintain a natural circadian rhythm that blue light can 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 how much blue light they block. Not all glasses that claim to block blue light are able to do so to the same degree.

Henley Sunnies block 80-95% of all blue light between 400-500nm, ensuring you the optimal conditions for interacting with devices that emit blue light, especially for prolonged periods.

Swanwick Night Swannies Blue Light Blocking Glasses are FDA registered and have been extensively researched, designed, and manufactured specifically to provide protection from UV and blue light rays and reduce glare from the sun by combining polarized lenses with special blue light reflecting coatings which work effectively to protect your eyes.

We design and manufacture our Henley Sunnies to the same exacting standards as our Night Swannies, but with lenses that reduce glare from the sun in outdoor conditions, as well as providing UV and blue light protection.

All Swannies are made with high-quality acetate, TR-90, 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!

Normal sunglasses aren’t engineered to block blue light the way our sunglasses do. Our Henley Sunnies block 80-95% of all blue light between 400-500nm, which studies have shown is the most harmful part of the blue light spectrum.

During the day, some of the blue light spectrum (between 450-500nm) is important to get through your lenses, because this type of blue light exposure during the day is key for giving your body the signals that it is daytime and supposed to be awake.

The only way to get accurate transmission data is to ask the company for a blue light transmission report conducted independently under controlled lab conditions. We have this report available upon request and encourage you to do this research in your product comparison.
