FOG WIPER for Swimming Goggle
GOGGLE NOT INCLUDED!  This fog wiper is a manual device that allows the user to slide a wiper/magnet on the outside of the glass, causing an inside wiper/magnet to move in unison and wipe off fog. This works with all types of swimming goggles including those with prescription lenses, and with contact lenses. SIMPLE! Wide-i fog wipers for scuba diving masks, snorkel masks, professional dive helmets, ski and snowboard goggles, airsoft and paintball masks, and Firefighter masks are also available at Amazon. Note that the unit price (quantity=2) is for 2 pairs of magnets, since swimming goggles normally have 2 lenses.
