Blocking light Perfectly- This sleeping eye mask features a patented nose wing design. The bottom of the eye mask is filled with elasticated cotton, which can be adjusted at will, and thus is very effective at blocking any light coming in through the nose area. No pressure on the eyes - This sleeping mask is designed with soft cotton delta side wings, which prevent any unwanted shifting of the mask, and effectively disperses the pressure on your eyes and head, so that your eyes won’t feel any pressure while wearing it. Super soft and comfortable - This sleeping mask uses four layers of super breathable fabrics, including cotton, flexible foam and a modal fabric. The side touching the skin is made from super soft modal fabric, which is incredibly soft to the touch.
