Dry eye is a medical condition that occurs when the body does not produce enough tears. Since tears are the only source of lubrication for the eyes, they become very dry and irritated when the tears are unable to properly do their job. This can be caused by a number of different reasons including aging, side effects from medication, failing to blink regularly and windy or smoky environments.
Dry eye can cause a lot of complications, so it is best to find a way to effectively lubricate the eyes as soon as you experience some symptoms.
Dry eye typically causes a distinct set of symptoms. A few of the most common symptoms you will experience are redness, light sensitivity, blurry vision, eye fatigue, and a burning sensation on the eyes. All of these issues will generally affect both eyes at the same time. It is very rare to have a problem with tear production in only one eye. If you are dealing with these symptoms on a regular basis, then it is time to get checked out by a medical professional.
The doctor will have to perform a series of tests in order to diagnose your condition. They will start out by doing a rigorous eye exam. The next step is to measure the volume of your tears by placing a special strip of paper under your eyelids for five minutes. The doctor will also measure how long it takes for your tears to evaporate. The information gained during these tests will be used to determine the best treatment plan.
