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.
You simply have a broken blood vessel, and itâs rarely as bad as it looks. The 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.
