Goggles help protect the eye from dirt, rocks, dust and other loose particles when riding. This is particularly important since motocross is ridden on outdoor dirt tracks. Motocross goggles have foam liners which seals the eye area, anti-fog lenses and coloured lenses for different light conditions. Goggles also have clear plastic lens covers that can be torn off or rolled off during a race so the goggle remains clean and clear while riding.
