Scuba Diving Mask Fog Wiper

This fog wiper is a manual device that allows the user to slide a magnet on the outside of the glass, causing an inside magnet to move in unison and wipe off fog. SIMPLE! This product works even with prescription lens masks. Note that the unit price (quantity=1) is for ONE pair of magnets; If your mask has two separate lenses, you must order TWO pairs. Wide-i fog wipers for swimming goggles, professional dive helmets, and fire fighter masks, are also available at Amazon. ....read more
