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.
