Blue Light Blocking Glasses - Cat Eye

Cat Eye Night Swannies feature blue light blocking lens technology that blocks 99% of blue light. With a style that’s suitable for both men and women, you can look amazing while benefiting from Night Swannies blue light blocking technology.

For Sleep

• To optimize your sleep, Night Swannies should be worn at least 1-2 hours before bedtime continuously.

• Try not to take them off at all until you have turned off all lights and devices are already in bed ready to sleep.

• Some people find better results from wearing them even earlier and we encourage you to experiment to find what works for you.

For Blue Light Protection

• Night Swannies can also be used during the day to protect your eyes from excessive blue light exposure.  Eg, when using digital devices for prolonged periods.

• We do not recommend you wear Night Swannies continuously for the whole day.

• Take regular breaks and allow some natural light exposure to ensure your body knows it’s daytime.
