What Causes Dry Eyes?

Your eyes need sufficient quality tears to stay healthy and lubricated. If not, you could develop dry eye disease. Millions of people in the U.S. suffer from this condition. Blurred vision, a burning sensation and mucus around the eyes often characterize dry eyes. Don’t wait long to see an eye doctor if you experience any of these symptoms.

Environmental Factors

Dry climate, high altitudes, exposure to wind and indoor conditions like air conditioning or central heating can cause or exacerbate dry eyes. Cigarette smoke exposure, whether first-hand or second-hand, can irritate the eyes and lead to dryness.

Aging

Tear production tends to decline after 50, increasing the likelihood of dry eyes. Age-related hormonal changes can also increase the risk of this eye condition. For instance, women going through menopause are more prone to develop dry eyes. 

Contact Lens Wear

Wearing contacts can reduce the amount of oxygen reaching the cornea, causing irritation and dryness. It might be worth discussing with your optometrist the possibility of switching to a different lens type. They might also recommend using eye drops designed for contact lens wear. 

Medical Conditions

Autoimmune conditions such as Sjögren’s syndrome, rheumatoid arthritis and lupus can affect the body’s moisture-producing glands, leading to dryness in the eyes and mouth. Health problems that can cause dry eyes include diabetes, vitamin A deficiency and thyroid disorders. Certain medications for high blood pressure, allergies and depression can also heighten your risk for this eye condition. 

Extended Screen Time

Today, it isn’t uncommon for people to spend hours staring at computer screens, smartphones and other digital devices. It’s easy to forget to blink when you’re in front of your monitor or cellphone. As a result, your eyes might get dry. To keep your eyes lubricated and avoid digital eye strain, follow the 20-20-20 rule. It’s where you stare 20 feet away from the screen for 20 seconds every 20 minutes.
