How do I prevent scratches on my spherical goggle lenses?

Never wipe a dry lens—always rinse with water first to float away abrasive particles. Use only clean microfiber cloths and pat rather than wipe when possible. Store goggles in a soft bag inside a hard case when not in use. Never place goggles lens-down on any surface. Keep them away from car keys and other sharp objects in bags. The larger surface area of spherical lenses means more exposure, so disciplined care habits are especially important. Consider the replacement cost of a spherical lens ($50-120) as motivation for proper care.
