The strong blue light emitted from your phone, tablet or laptop can have a negative impact on your circadian rhythm by tricking your body and mind to stay awake. Swannies are stylish glasses that block the harmful blue light emitted from electronics to help you sleep better. In SleepScore’s validation study, people who wore Swannies in the evening had increased deep sleep and felt they fell asleep faster, slept better, and were more rested in the morning.
