It's important to understand this condition, its causes and the treatments available.
In this article, we explore dry eye symptoms, possible causes, and medical and natural treatments that can relieve dry eyes. Read on to learn more about how to identify, manage and relieve dry eyes.
Dry eyes: understanding the problem
What is dry eye?
Dry eye, also known as dry eye syndrome, is a common condition characterized by a lack of tears or poor-quality tears. Tears play an essential role in lubricating the eyes and keeping them moist.
When your lacrimal glands don't produce enough tears, or produce poor-quality tears, your eyes can become dry, irritated and painful. Dry eyes can lead to stinging, burning, itching, grittiness or even vision problems.
Impact on quality of life
Dry eyes, when left untreated, can significantly affect your quality of life. Blurred vision, photophobia, irritated or painful eyes can affect your ability to read, use a computer, drive and carry out daily activities. Some severe cases of dry eye can even lead to damage to the ocular surface.
Fortunately, there are several treatments available to relieve the symptoms of dry eye. Consult your optometrist or other eye care professional if you think you may be suffering from this condition.
