This sleep mask is impervious to light and ensures a higher comfort while sleeping. The mask shields your eyes from the light and at the same time it helps to relax your eyelids. While traveling on a plane, train or in a car, for example, these eye masks are a great aid in enabling you to relax and get some rest or even sleep undisturbed. The soft nylon fabric feels comfortable on your skin and the elastic band guarantees that the mask stays securely where it should.
In addition these masks are used during meditation and they can also help against headaches.
