After you fire up the barbecue grill, the charcoal briquettes you use as fuel are eventually reduced to a pile of charred remains and ashes. This residue contains recycled plant material and naturally occurring minerals, but it may also contain harmful chemicals.
Some of the blood in the sclera has turned yellow, like a bruise. 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.
Eye bleeding is most often caused by injury to the eye, such as blunt trauma or penetration of something sharp into the eye. Other causes of eye bleeding include malformations of the blood vessels in the eye, cancer in the eye, or severe inflammation of the inner portions of the eye. Subconjunctival hemorrhages that appear as red spots on the whites of the eyes may appear for no apparent reason and are typically not a serious problem.
