Has anyone had issues with artifacts in night vision mode?

One of my cameras has started producing a small glare on a certain part of the screen but only in night vision mode. If so how did you rectify thr blemish.

Initially i thought it was a smudge on the lens or something

Probably too close to a wall or something. The IR light is reflecting in the lense.
