It is irritating and hinders their ability to engage in their sport safely. Our system releases a gel that instantly defogs your goggles or swim mask. It also keeps your lenses defogged longer-you don't have to reapply every few seconds. It is long lasting unlike all the other brands out there. Enjoy the Freedom without Fog The sponge contributes to the elimination of the grease film of the glass produced by the vapors of the silicone after its vulcanization. Given its neutral pH (7.0) and the zero irritability of its components, it is ideal for use on surfaces near the eyes. Its base is only deionized water and does not contain any type of organic solvent (isopropyl alcohol, ethyl, glycols, etc.), since, under immersion conditions, they could evaporate and affect the surfaces and eye fluids. Applied correctly (according to instructions of use) creates a protective film that prevents the condensation of microdrops on the surface where it has been used. Its low concentration in surfactants, along with the silicone it incorporates, extends its effectiveness for about 2 hours (depending on conditions). 0.5 oz (15 ml) container with applicator sponge.
