Our seye masks were designed by the Christine Lenz, an esteemed sleep expert from Nuremberg in Germany. They are wonderfully soft and snug, made of organic cotton or non-violent breeding and harvesting of silkworms and silk (Peace Silk) and cover the eyes perfectly. The sleep masks are not only suitable as protection from disturbing and bright sunlight. They also help those CPAP patients whose eyes are irritated by the draft of the CPAP mask. You can comfortably protect yourself from this, by wearing one of our eye masks.
