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.
Eye Problems and Blood in the Eye. Sometimes small blood vessels in the whites of the eyes break and cause a red spot or speck. This is called a subconjunctival hemorrhage. The blood vessels may break because of sneezing, coughing, vomiting, straining, or bending over, but sometimes there is no clear cause. The blood may look alarming, especially if the spot is large. It is usually not a cause for concern and will clear up in 2 to 3 weeks.
Broken blood vessels occur when a tiny blood vessel bursts under the clear surface of your eye (also known as the conjunctiva). Think of it as a painless bruise on your eye. In spite of its gruesome appearance, a subconjunctival hemorrhage should not cause any pain, discharge, or change in your vision.he official name for a broken blood vessel in your eye is a subconjunctival (sub-kon-junk-TIH-vul) hemorrhage. Symptoms of this condition include: 1  Bright red patch on the white of the eye. 2  A slight sense of fullness in the eye or under the lid. 3  Very mild irritation of the eye.
