What Causes Dry Eye? Common Triggers and Risk Factors

Dry eye can develop when your eyes do not produce enough tears or when your tears evaporate too quickly. For some people, symptoms are occasional. For others, dry eye becomes a persistent problem that affects reading, computer use, driving, and everyday comfort. At The Pataskala Vision Center, we help patients in Pataskala and surrounding areas understand what may be contributing to their dry eye symptoms and determine the appropriate next steps for relief.

How Your Tear Film Affects Dry Eye

Healthy tears contain a balance of water, oil, and mucus that keeps the surface of your eyes lubricated and protected. When this balance is disrupted, dry eye symptoms can develop.

One common cause is meibomian gland dysfunction, or MGD. The meibomian glands in the eyelids produce the oily layer of tears that slows evaporation. When these glands become blocked or do not function properly, tears can evaporate too quickly and leave the eyes feeling dry or irritated.

Common Dry Eye Triggers

Everyday habits and environmental conditions can make dry eye symptoms worse. Common triggers include:

•          Extended computer, tablet, and smartphone use

•          Wind, smoke, and dry air

•          Heating and air conditioning

•          Seasonal changes and low humidity

•          Wearing contact lenses for extended periods

•          Not blinking frequently enough during concentrated tasks

•          Certain medications that reduce tear production

•          Dehydration

For patients who spend much of the day working on digital devices, reduced blinking can be an especially common contributor. Taking regular screen breaks and making an effort to blink fully may help support a healthier tear film.

Dry Eye Risk Factors

Some people have a greater risk of developing chronic dry eye. Tear production naturally tends to decrease with age, making dry eye more common among older adults. Hormonal changes may also affect tear production and tear quality.

Certain medical conditions, eyelid inflammation, allergies, and some medications can contribute to symptoms as well. Previous eye procedures or problems with the eyelids may also affect how tears spread across the eye. Because several factors can contribute at the same time, determining the cause of dry eye is important before choosing treatment.

Signs You May Have Dry Eye

Dry eye does not always feel like simple dryness. Patients may experience burning, stinging, redness, fluctuating or blurry vision, light sensitivity, tired eyes, or a gritty sensation. Some people also experience excessive watering because irritated eyes may respond by producing reflex tears that do not provide lasting lubrication. If these symptoms keep returning, an eye examination can help identify whether dry eye, MGD, or another eye condition is responsible.
