Violent coughing, heavy lifting, vomiting and powerful sneezing are the leading causes of subconjunctival hemorrhage. Injury from a chronic eye infection, trauma and rubbing the eye may result in a broken blood vessel in the eye, as published by Mayo Clinic.

The conjunctiva is a flimsy, transparent membrane that protects the eyeball, according to MedicineNet. It contains numerous blood vessels as well as nerves. These blood vessels only become visible when various factors inflame the eye. The blood vessels are fragile and break easily resulting in bleeding under the conjunctiva.

The most common sign of a blood vessel hemorrhage is a dark red or a bright red spot on the white part of the eye. Apart from the bloody looks of the eye, a ruptured blood vessel does not affect vision, and there is no pain or discharge. The only side effect may be a scratchy sensation on the surface of the eye, as claimed by Mayo Clinic. Artificial tears can help soothe any discomfort, but the subconjunctival hemorrhage resolves on its own within a couple of weeks.
