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.
Under certain circumstances, one of these tiny vessels can blast. It is usually not a case of severe complication and thus, there is no need to treat it usually, unless it takes more than normal time to get healed by itself. Causes of Broken Blood Vessel in Eye. The conjunctiva contains a few nerves and minor veins. These veins are large in number and scattered throughout the sclera. They are delicate and can be damaged with slight stretch break. A slight trauma, direct blow or pressure on the eye can cause these minute veins to be ruptured. Some of the causes for subconjunctival hemorrhage are: Eye surgery, including LASIK and cataract surgery. Accidental injury. Coughing. Excessive rubbing of eye. High blood pressure. Bleeding disorder.
