You’ll find most clear-lens blue blockers on the market only block blue light up to 420nm. Day Swannies, however, block 98% of blue light at 400 nanometers, graduating to 45% at 450nm. Our lenses are optimized to let just the right amount of beneficial blue light through while blocking the harmful spectrums of blue light.
Day Swannies block between 21-45% of blue light between 450-500 nanometers. This allows the good blue light that is beneficial to your health during the daytime to get through, while still protecting your eyes from over-exposure to harmful blue light.
Day Swannies can help prevent symptoms of digital eye strain such as sore eyes, headaches, and fatigue when worn during prolonged use of electronic devices.
While you work, Day Swannies are working to optimize the blue light you’re exposed to, helping you control your environment to perform at your peak.
With our increasingly digital lives, there’s almost non-stop exposure to harmful artificial blue light. Fortunately, Day Swannies blue light 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. In the evening we recommend wearing Night Swannies to block the spectrum of light that suppresses the production of melatonin, the hormone essential to quality sleep.
Research shows that blue light between 400 and 450nm causes 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, Day 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.
Day Swannies block 46-98% of blue light between 400-450nm, ensuring you the optimal conditions for interacting with devices that emit blue light, especially for prolonged periods.
Day Swannies are designed with an almost-clear lens. They’re specifically designed for screen-time during the day, as they block between 46-98% of blue light between 400-450nm (the most harmful part of the blue light spectrum).
Our clear blue light glasses (Day Swannies) were thoughtfully engineered to allow some of the beneficial blue light between 450-500nm to get through, as exposure to this spectrum of blue light during the day is important for giving your body the signals that it’s daytime and should be awake.
Swanwick Night 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.
We design and manufacture our Day Swannies to the same exacting standards as our Night Swannies, but with lenses that allow the beneficial daytime blue light spectrum through to keep us alert and operating at your peak.
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!
The Day Swannies with their almost-clear lens are specifically designed for screen-time during the day. They block between 46-98% of blue light between 400-450nm, 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. The Day Glasses give you these benefits while protecting your eyes from the harmful spectrums of blue light.
The Day Swannies with their almost-clear lens are specifically designed for screen-time during the day. They block between 45-98% of blue light between 400-450nm, which studies have shown is the most harmful part of the blue light spectrum.
They allow some blue light rays in the range of 450-500nm to get through, as exposure to this range during the day is important for giving your body the signals that it is daytime and that it should 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.
