Your face gets hot when your nervous which leads to fogging up your glasses like when your out on a cold day and then come into a warm house your glasses cloud up.
Most people only breathe thru one nostril, in the morning when you put on your glasses the air that you are exhaling will fog only one side:))
First thing your glasses have to be cold. Second you have to be in a warm/hot area. Glasses "fog up" because when the warm/hot water vapor gets near the cold glasses, it turns into the "fog" you see on glasses.
Before you enter a room from outside gently wipe your glasses with something to get rid of the fog :)
They wear glasses because of the fog in the tv world. The glasses work sorta like goggles work in water.
Well, water if you are talking about natural fog. Ice and fluid if you are talking about a machine
Because in winter your glasses become very cold and the water particles in the air condensates on them.
Fog, sea mist, smog, dust storm, dirty glasses, dementia, or hallucinations.
It certainly adds effect.
yes i have done it for years but is t is cold they might fog up.
Fog is mostly considered a type of stratus cloud. This is because those clouds are known for being close to the ground.
It depends mainly on the visibility - how far you can see.
Upon entering the warm building, the warm air around your cold glasses condense to form miniscule water droplets that will cloud your vision.
