What's "eyes wide shut" mean? Is it opposite of "eyes wide open"?

Rebecca

"Eyes wide shut" has a bit of a metaphorical meaning, as it's used to describe a person who refuses to believe or accept the reality of something, even when the truth is obvious and clear to see. Thus, we can consider it to be the opposite expression to "eyes wide open," which means to be aware and clear-minded. Ex: She has her eyes wide shut and won't accept the truth. Ex: I admit that I had my eyes wide shut about this matter.
