What Causes Dry Eyes?

Dry eyes can make everyday activities like reading, driving, and using a computer uncomfortable. You may notice burning, irritation, blurry vision, or a gritty sensation that makes it feel like something is stuck in your eye. At Quality Eye Care in Jacksonville, FL, we help patients understand what causes dry eyes and identify appropriate treatment options to improve their comfort and eye health.

Understanding Dry Eye Syndrome

Dry eye syndrome occurs when your eyes do not produce enough tears or when tears evaporate too quickly. A healthy tear film helps keep the surface of your eyes smooth, lubricated, and protected.

When this balance is disrupted, your eyes can become irritated and inflamed. Some people experience occasional dryness, while others develop chronic symptoms that require ongoing management.

Common Causes of Dry Eyes

Several factors can contribute to dry eye symptoms. Understanding these triggers can help determine the best approach to relief.

• Aging and Hormonal Changes: Tear production may decrease with age. Hormonal changes, particularly during menopause, can also contribute to dry eyes.
• Prolonged Screen Time: Spending hours on computers, smartphones, or tablets can reduce blinking frequency, allowing tears to evaporate faster.
• Environmental Conditions: Air conditioning, indoor heating, wind, and low humidity can increase tear evaporation and worsen dryness.
• Medications and Medical Conditions: Certain antihistamines, antidepressants, and other medications may reduce tear production. Conditions such as Sjögren's syndrome can also affect tear function.
• Meibomian Gland Dysfunction: Blocked or poorly functioning oil glands along the eyelids can cause tears to evaporate too quickly, leading to irritation and discomfort.

Contact lens wear and eyelid inflammation can also contribute to dry eye symptoms, especially when the tear film is already unstable.

Recognizing the Symptoms of Dry Eyes

Dry eye symptoms can vary depending on the underlying cause and severity. Common signs include burning, stinging, redness, sensitivity to light, fluctuating blurry vision, and the sensation of having sand in your eyes. Excessive watering can also indicate dry eyes. When the eye's surface becomes irritated, it may produce reflex tears that do not provide lasting lubrication. If symptoms persist or interfere with daily activities, scheduling an eye examination can help identify the cause.

How Can Dry Eyes Be Treated?

Effective dry eye treatment depends on what is disrupting your tear film. At Quality Eye Care, we evaluate your symptoms and eye health to determine an appropriate treatment approach.

For mild dryness, artificial tears, taking regular screen breaks, and reducing exposure to direct airflow may provide relief. Patients with persistent symptoms may benefit from prescription medications or treatment for underlying eyelid conditions.

Because dry eye symptoms can overlap with other eye conditions, a professional evaluation is important. Significant eye pain, sudden vision changes, or severe redness should receive prompt medical attention.
