Blood is not moving and is spread like ketchup over the plastic wrap.

Some commonly used culprits are: Corneal scratches; Injuries caused by sand, dust, or overuse of contact lenses; Sometimes, a bright red spot, called a subconjunctival hemorrhage, will appear on the white of the eye.

Bleeding often happens after straining or coughing, which causes a broken blood vessel on the surface of the eye.
