Learning how to prevent scuba mask fogging isn't just about comfort—it's about safety, situational awareness, and actually enjoying what you paid to see down there.

This guide walks you through every proven method to keep your mask crystal clear, from the initial prep of a brand-new mask to the pre-dive rituals I still use after four decades underwater.
