A mineral or stone-like formation in the tear ducts; a tear stone or concretion in the lacrimal system.
From Greek 'dakryon' (tear) and 'lithos' (stone). Medical term describing calcified or mineral deposits that form in tear ducts.
Just like kidney stones form in kidneys, 'dacryolites' (tear stones) can form in tear ducts from mineral buildup—they're rare but can be incredibly uncomfortable when they occur.
