Blood supply to the eye comes from the blood vessels, more specifically from the ophthalmic artery. Anything wrong happens to these blood vessels, the effect is observed in the form of red areas in the white part of the eye. For instance, if blood vessels located inside the eye rupture or break, the blood gathers in the front portion of the eye. The accumulated blood, thus appears as red spots around the eyes. Actions such as lifting heavy objects can also make the eyes red.
