Dry eye is one of the most irritating eye conditions you can experience. It causes pain, blurry vision, and light sensitivity. Sometimes, it may also create too many tears, a condition doctors refer to as reflex tearing. It happens when your eyes send a distress signal to your nervous system for more lubrication. Consequently, the body sends a flood of tears to make up for the eye dryness.
Myopia, or nearsightedness, is a refractive error that makes distant objects appear blurred or fuzzy. However, people with myopia can see nearby things quite clearly. Myopia is very common. The American Optometric Association estimates that about 30 percent of people in the U.S. are nearsighted. An optometrist and ophthalmologist can diagnose this condition through an eye exam.
