In this video:
The “fog” you may sometimes experience on your glasses or goggles occurs when atmospheric humidity near the lens condenses; this happens due to a relatively significant discrepancy between the temperature of the lens and the surrounding air. As the surface attempts to reach an equilibrium between the two temperatures, heat energy is given up; and, as the energy within the gaseous water molecules decreases, they form into tiny water droplets on your lens, otherwise known as “fog.”
