100% Light Blocking
Most of these sleep masks have extra cheek and nose padding at the bottom of the mask to provide excellent light blocking (Dreamer, Dream Essence, Opulence, and Solitude sleep masks)
The remaining sleep masks have deep eye cavities that relieves pressure off of your eye lashes and eyes with padding around the eyes to completely block out light (Escape and Total Eclipse sleep masks)
The Silk Sleep Mask does not have extra padding or eye cavities, but it blocks out light by completely covering the eyes and a large area of the face.
-Most users should get 100% of light blocked from this range of sleep masks.
