Better sleep

Do you have trouble sleeping after working on the computer or watching tv? By wearing Night Swannies whilst using digital devices you'll experience less eye strain, headaches, and protect your eyes from harmful blue light. Night Swannies are scientifically proven by a 3rd Party Lab to improve your sleep quality. To optimise your sleep, we recommend wearing Night Swannies at least 1-2 hours before bedtime. Each person is different, so you may benefit from wearing them even earlier in the evening- we encourage you to experiment and find what works best for you. 

Reduce digital eye strain

Night Swannies can also be worn during the day to protect your eyes from excessive blue light exposure. We recommend wearing your Night Swannies when using digital devices for prolonged periods of time. Make sure to take regular breaks and allow your eyes exposure to natural light to ensure your body knows it's daytime. If you're interested in extended protection during the day we'd suggest our Day Swannies which can be worn continuously throughout the day.
