Some medications such as birth control pills, Aspirin and estrogen therapies are known to be a cause of broken blood vessels on the face. They increase blood pressure, causing breakage of facial blood vessels and hence the redness common on the cheeks and around the eyes. Aging is also a cause of broken blood vessels. The red spots common on the elderly are not the color of aging skin. They are the result of broken blood vessels. As the human body gets older, it becomes fragile and prone to damage.
Subconjunctival hemorrhage, also known as subconjunctival haemorrhage and hyposphagma, is bleeding underneath the conjunctiva. The conjunctiva contains many small, fragile blood vessels that are easily ruptured or broken. When this happens, blood leaks into the space between the conjunctiva and sclera. Such a hemorrhage may be caused by a sudden or severe sneeze or cough, or due to hypertension or as a side effect of blood thinners.
