Environmental and Biological Factors Can Cause Dry Eye

Dry eyes occur when tears are not able to provide enough lubrication. This can happen for several different reasons. Some people are simply not able to produce enough tears. Genetics can play a critical role in tear duct development. Other reasons primarily stem from environmental causes.

Air conditioning is a frequent culprit of dry air that can prevent tear proper tear production. Sitting on an airplane with limited air circulation and lack of moisture in the air can also create eye dehydration. Riding a bicycle or motorcycle where eyes face an exorbitant amount of wind is also problematic for many riders. Prevention of dry eyes during these times is especially important.

Even natural environmental causes can create dry eyes. Allergies are a common cause for red, itchy eyes. When pollen irritates the eyes, they can become dry and sore. Those who experience excessive eye dryness often report a stinging or burning sensation.

Eye infections can also cause eyes to become dry and painful. Since the tears protect the eye’s surface from harmful bacteria, without adequate tears, infections may increase. To increase the quality of life, keeping eyes moist can prevent pain and irritation.

Eyes Can Be Affected In Multiple Ways

Contrary to popular belief, dryness can affect one or both eyes depending on the cause. Frequent symptoms exist on a spectrum ranging from mildly irritating to blurred vision. Depending on the intensity of each symptom, visiting a doctor may be advised.

Common symptoms experienced by those who suffer from dry eyes include:

• Eye discomfort
• String-like mucus
• Redness
• Light sensitivity
• Blurred vision

Eye discomfort is a broad category that encapsulates a variety of symptoms. Dry eyes can often lead to mild discomfort from a stinging, burning, or itching sensation. If eyes are sensitive to light, this can cause a throbbing pain felt around the eye. Wearing contact lenses if eyes are irritated or red is not recommended.

The Importance of Tear Production Is Crucial

Proper tear production will help fight dry eyes. Although there are many environmental reasons for improper tear production, natural causes include aging, certain medical conditions, and glandular damage.

To prevent tear production from occurring, avoiding smoke, wearing sunglasses, and using artificial tears are all effective methods for eye hydration. By preventing or treating dry eyes, eyes can function comfortably and effectively throughout the day.
