Warm compresses are a cornerstone in the management of dry eye and blepharitis. The heat from warm compresses or eye masks such as the Oasis Rest & Relief Eye Mask makes the oils of the Meibomian glands more liquid and likelier to be expressed into the tear film. With every blink therefore your body's own oil like substance called meibum, intergrates with your own natural tear film. These oils also help to retain the water layer in your tears and prevent tear evaporation. Some doctors will recommend holding a warm compress to your eyelids, however the heat from an Oasis Rest & Relief Eye Mask will last up to 20 minutes. This soft cloth eye mask is filled with silica and features and adjustable strap for gentle compression.
