The lenses of glasses fog up when we come in from the cold because of a phenomenon called condensation. The lenses are cold, and when we enter a warm room, moisture in the air comes into contact with the cold lenses and collects there. The moisture in the air in the room has some amount of thermal energy that keeps it in the form of a gas or a vapor. But the cold lenses "steal" that thermal energy from moisture coming into contact with them, and the water molecules collect there. Those water molecules no longer have the thermal kinetic energy to remain in the air and condenseon the lens. There's a bit of extra detail in there, but nothing you can't handle.
