Swanwick Day Swannies

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.

Description

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.
