“Glimpse” and “glance” are not the same thing. Don’t use one when you mean the other.
If you glimpse something, you get a quick look at it: Jane glimpsed something moving outside the window.
The noun indicates the product of a quick look at something: Jane caught a glimpse of something moving outside the window.
If you glance at something, on the other hand, you look at it briefly: Joe glanced at the window.
Likewise, the noun form refers to the action of looking: Joe and Jane exchanged meaningful glances.
(What’s lurking outside that window? I don’t know. But Jane and Joe don’t seem terribly surprised to find out that it’s there.)
