He wiped [his glasses] against his grubby wind-breaker... He smeared the sweat from his cheeks and quickly adjusted the spectacles on his nose.

I have difficulty understanding how the person "smears" the sweat from his sweat. The dictionary meaning of smear is to blur the outline of, to spread a substance over something, or to coat something carelessly with a greasy substance.
Applying these meanings, does the line mean the character is coating his cheeks with sweat? But is the sweat not coming off of his cheeks? How is he spreading/coating/blurring his cheek with sweat? And the sample sentences I found are usually smear on something, or smear with something. What does "smear from" in the quoted line mean? Here, the quoted line seems to read something like "he wipes the sweat from his face".
