Haemolacria is a physical condition that causes a person to produce tears that are partially composed of blood. It can manifest as tears that are anything from merely red-tinged to appearing to be entirely made of blood.

Haemolacria is a symptom of a number of diseases, and may also be indicative of a tumor in the lacrimal apparatus. It is most often provoked by local factors such as bacterial conjunctivitis, environmental damage or injuries.
