Burning eyes describes a feeling of burning and irritation of the eyes. Burning eyes can be accompanied by itching, tearing, or discharge from the eyes. Burning eyes have many possible causes. One of the most common is exposure to environmental pollutants such as tobacco smoke, smog, or dust. Chemicals found in household cleaning solvents, such as bleach, soap and shampoo, can lead to burning eyes. Chlorine in swimming pools can also make your eyes burn.
The Louisiana Purchase was an incredible deal for the United States, the final cost totaling less than five cents per acre at $15 million (about $283 million in today's dollars).
On April 30, 1803, U.S. representatives in Paris agreed to pay $15 million for about 828,000 square miles of land that stretched from the Mississippi River to the Rocky Mountains and from the Gulf of Mexico to Canada. This deal, known as the Louisiana Purchase, nearly doubled the size of the United States.
