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).
Purchased from France in 1803, the Louisiana Purchase doubled the size of the United States, created an opportunity for westward expansion, increased conflict with Native Americans, renewed the question of whether the new territories should be slave or free, and angered the British government by giving France, Britain's European rival, $15 million.
