In Canada I would say "My glasses fogged up". This happened every time I went into a warm room after being outside in the cold winter. I have great experience with foggy glasses!

Thank you, DavidK. What is the replacement for Vapor in daily life? My guess is "steam", is that correct?

You wouldn’t talk about glasses being “blurred.” My vision was blurred. Something blurred my vision. The image was blurred. Misalignment of the lenses blurred the image. The distinction between full-time and part-time employees is blurred by the new policy. “Vapor” is used more in science than daily life.

The vapor fogs up my glasses. OR The vapor steams up my glasses.
