Due to its neutral pH (7.0) and its components null irritability, its perfect for surfaces used near the eyes. Its basis its only deionised water and it doesnt have any kind of organic solvent (isopropyl or ethylic alcohol, glycol, etc.), because in diving conditions they could be evaporated and affect the ocular fluids and surface.
Applied correctly (following the use instructions) it creates a protector coat that avoids the condensation of micro drops over the surface where it has been used. Its low concentration in surfactants, with the silicone that incorporates, extends its effectiveness during 2 hours approximately (depending on conditions).
As its formulated, its the perfect combination between effectiveness and use safety, for diving and swimming activities.
