The Dry Eye Relief Mask, D.E.R.M.™ PLUS Comfort Cover™ PLUS 100 cotton liners is a moist-heat compress for mild dry eye from EyeEco. The mask contains Silica beads which naturally attract moisture from the air and release it when microwaved. Heating the mask for 20 seconds will provide soothing moist-heat relief for 5-6 minutes. EyeEco supplies complimentary samples of liners with the D.E.R.M. which can be moistened and applied to the mask prior to heating to extend the treatment to 7-9 minutes. D.E.R.M.™ is hypoallergenic and can also be used to create cold therapies for allergy relief.
