When should I wear Swannies Blue Light Blocking Day Glasses?

Swannies Day Glasses should be worn any time you are using devices with digital screens during daylight hours. This will allow you to block the most harmful part of the blue light spectrum (between 400-450nm) whilst allowing natural levels of beneficial blue light through, which will help you to regulate your sleep/wake cycle.

When the sun goes down, you need to block more of the blue light spectrum, to signal to your body that it’s time to get ready for sleep. For this, we recommend switching to our orange tinted Swannies Night Glasses, which are designed to block the full spectrum of blue light, including the wavelength shown to suppress melatonin production (450-480nm).
