Our blue light blocking glasses is worn best during the evening and night, both on and off screens. The blue light from the screens at night will disrupt your sleep hormone, melatonin and worsen your sleep. Here is a guide when to wear our different lenses:

Sleep lens: 99% HEV blocking most suitable 1-2 hours before bed for best blue light blocking ability.

Relax lens: 97% HEV blocking most suitable 2-3 hours before bed or if you want your vision to be less red. 

Relief lens: 84% HEV blocking most suitable for afternoons when you spend a lot of time in front of screens to reduce eye strain.
