Most people will experience dry eye at some point in life. During the summer months and allergy season, the incidence of dry eye complaints skyrockets. Many people ask us, “What causes dry eyes?” So, we put together this shortlist of the top causes of this irritating experience.

Working in front of a computer screen

More and more, people who work in offices not only stare into a computer screen all day, but they also go on to watch TV and films on larger screens of the same kind at night. Digital screens emit harsh blue light that has been shown to damage eye tissue causing all manner of problems, including dry eye.

Medical conditions

Numerous medical conditions and medications will contribute to the likelihood of a dry eye. Diabetes, rheumatoid arthritis, high blood pressure, and others can all contribute to dry eyes. Medications such as antihistamines, beta-blockers, and diuretics can also exacerbate the problem.

Blocked glands

Persons suffering from Meibomian Gland Dysfunction (MGD), a condition that causes blocked and dysfunctional glands located in the eyelids which produce tears and oils that lubricate the eye, are likely to experience dry eye. If this lubrication is lacking, the eye will become dry, leading to irritation and possible distress.

Reduced Tear production

In addition to blocked glands, insufficient tear production is another common cause of dry eye. Some individuals experience rapid evaporation of tears, while others produce too little natural saline to lubricate the eyes.

Other external factors

Anyone who lives or works in dry, dusty, or smoky environments is likely to experience dry eye at some point. Sometimes wearing goggles or using eye drops can help. Anyone who spends significant amounts of time around smoke should consider a change to protect their overall health.
