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.

When you have a cold shower does the bathroom mirror fog up?
No. The steam from a hot shower fogs the mirror.
Why doses the mirror fog up when you take a shower using the word dewpoint?
Warm air can hold more moisture than cold air. The dew point in the shower room is at or below room temperature. The vapor from the hot water in the shower warms up the air in the room, and the mirror surface is colder with low dew point, so the water condenses on it causes it to fog up since it cannot hold the moisture. The same thing happens when you leave an air conditioned auto with glasses on - they fog up if the air outside is warm with high dewpoint - lots of moisture

What are the changes in matter when eyeglasses fog up?
The change of matter occurring when glasses fog up is a gas into a liquid otherwise known as condensation. this happens because the lack of energy in the gas particles cause the particles to bunch up and get closer together, they then form a liquid.
Why does the shower produce more steam than a bath?
In a bath there is less hot water vapour condensing into particles for you to see. Steam is made up of water vapour that you can't see. More fog is produced from a shower because cold air surrounding the hot water from the shower causes water vapour to change into small water droplets called fog not steam.
What is the role of a shower mirror?
A shower mirror is installed to assist the person taking the shower. Men may use it to help while shaving their face while women may use it for other facial grooming such as plucking or putting on face masks. Many shower mirrors do not fog up in the heat of the shower like normal mirrors.
