The higher levels of blue light emitted from digital screens can cause symptoms of digital eye strain such as eye fatigue, headaches, dry eyes and tiredness. Day Swannies® counteract the negative effects caused by blue light by filtering the harshest part of the blue light spectrum.

Fitover Day Swannies by Swanwick have been designed with precise standards so you always get a secure, comfortable fit over the top of your existing prescription glasses. For those who already wear glasses, these fitover blue light blockers easily slip over and attach to your existing frames, relieving you of eye strain resulting from using digital devices.
