A spray-on rain repellent enhances vision thanks to its water-repellent properties. These sprays are highly recommended for ski goggles.
Firstly, remove dirt from your glasses or ski goggles with a mild soap and rinse thoroughly with water. Shake the spray well before use and spray from a distance of about 15cm onto the outer surface of the glasses. Next, wipe the glasses or lens with a clean, lint-free cloth to ensure even coverage.
