Why is there blood in the corner of my eye? explanations please?

Hemorrhage: In the absence of surgery or trauma, if there is blood over the white of the eye (and it is painless and does not affect your vision), then it is a subconjunctival hemorrhage. This is a seepage of a small amount of blood from a thin walled vessel, releasing blood in the space under the conjunctiva and over the white sclera. These are benign, and will clear themselves with no need for treatment.
