Matthew Poole and continuators on Lamentations 3:49

49 Mine eye trickleth down, and ceaseth not, without any intermission .

The Prophet was deeply affected upon the prospect of this evil before it came, Ier. 9.1. and was now much more affected when he saw the judgment was come, he wept plentifully and constantly, as for their sins which had brought these judgments upon them, so for the judgments themselves as indications of Gods displeasure and wrath against them for their transgressions.
