Common Causes of Dry Eyes

Introduction

Many people may experience dry eyes from time to time. There are different reasons why a person may experience dry eyes, some of the most common reasons are from wind, dry air, or straining of the eyes. There could be health-related reasons for why a person may be experiencing dryness of the eyes. Age can also be a contributing factor to dry eyes. Certain medications can cause a person’s eyes to produce less tear drops.

Health-Related Issues

There are many health-related conditions that may cause dry eyes. Common medical conditions such as lupus, diabetes, thyroid disorders, and rheumatoid arthritis often cause dryness of the eyes. Scleroderma, Sjogren’s syndrome, and Vitamin A deficiency can also cause the condition. Tear gland damage may cause a person to have dry eyes due to inflammation or radiation of tear production. Eyelid problems may cause dry eyes because it makes it harder for someone to blink. If someone cannot blink correctly, then the tears will evaporate quickly resulting in dry eyes. Laser eye surgery may cause dry eyes because it can temporarily decrease tear production.

Tear Quality

Dryness of the eyes may result from poor tear quality. Tears are composed of oil, water, and mucus. If there are problems with any of these layers, it can alter the production of tears. If the oil glands don’t produce enough oil in the eyes, the tears may evaporate at a quick pace resulting in dry eyes. If not enough water is present in the eyes, the oil and mucus layers can touch and cause a stringy discharge. Water that is present in the eyes is needed for cleansing and washing away particles and other foreign objects. The mucus spreads the tears evenly throughout the surface of the eyes. If not enough mucus is present then dry spots can form on the surface of the eye.

Age & Medications

As a person ages their tear production tends to diminish; this usually happens around the age of 50. Postmenopausal women are prone to a lack of tears, this is believed to be a result of hormonal changes. There are numerous medications that may cause a decrease in tear production. Drugs used to treat high blood pressure, antihistamines, and decongestants often dry out the mucus membranes in the body. Hormone replacement therapy, antidepressants, and certain acne medications may also cause dry eyes.
