English Idioms About “Health”
Idiom: As blind as a bat
Meaning: If someone is as blind as a bat, they are nearly or completely blind or they are unwilling to recognize problems or bad things. This is a simile which is based on the erroneous idea that bats cannot see properly. In fact, bats are not blind; they use vision to navigate, especially for long distances. In addition to their ability to see, they use a sophisticated built-in sonar system, called echolocation.
Example: 1. Without her glasses, she is as blind as a bat. 2. He is as blind as a bat when it comes to his wife’s shameful behavior
