The person involved is effectively blind, either because of environmental conditions (their windshield is covered with snow or mud), someone blinded them (by light or throwing something in their eyes), or they've lost their means to see (lost glasses, lost visual device.) The examples should only be of either blindness or of serious inability to see.
Tropes that involve this problem:

- A man says to his wife, "Hey, maw, I'm hungry after driving all day. I'm gonna pull into that diner." Woman responds, "Paw, that's no diner, that's a school bus!" Cue jingle for the advertiser: a maker of windshield wipers.
- In an ad for eyeglasses, a woman yells out, "Taxi!", gets in the vehicle, tells the driver to go somewhere (avoiding a certain very busy street), and the camera pulls back in a Jump Cut to show she's in a police car.
Live Action TV
- A MythBusters episode testing the "dust kidnapping" scene from Body of Lies had them testing a safety system by obscuring their view in front (to simulate the dust that they would encounter). Unfortunately, their first "blinding" method (an opaque paper) worked too well; instead of the 10% visibility they were going for, they basically had zero visibility. Their safety system failed as a result. Their second method, using burlap sacks, gave them the required visibility level, and they were able to stay on course with the help of the safety system.
- This was the entire premise of the Mr. Magoo series of cartoons; the eponymous protagonist mistook all sorts of (often dangerous) things for other things because of his near blindness, yet always came out unscathed.
- An episode of The Flintstones has Fred going to the circus and becoming the star performer, because he walked out into the performers area and got into the act. The reason he's doing this is because he is wearing not the glasses he was prescribed, but accidentally took the optometrist's glasses instead, and is wearing them by mistake (and the optometrist's uncorrected vision is a lot worse).
