A subconjunctival hemorrhage (sub-kun-JUNK-tih-vul HEM-uh-ruj) occurs when a tiny blood vessel breaks just underneath the clear surface of your eye (conjunctiva). The conjunctiva can't absorb blood very quickly, so the blood gets trapped.

Broken blood vessels — also called “spider veins” — occur when they're dilated, or enlarged, just beneath your skin's surface. This results in small, red lines that spread out into a web-shaped form. They can develop anywhere on the body, but they're more common on the face and legs.

Stress is not a recognized cause of subconjunctival hemorrhage. The good news is, if you had a conjunctival hemorrhage, these are only cosmetically annoying but go away and do not endanger the vision.
