What Can Be the Causes for Dry Eye Despite Using Artificial Tears?

If you’re constantly reaching for artificial tears but still struggling with dry, irritated eyes, you’re not alone. While lubricating drops can provide temporary relief, they don’t always address the root cause of dry eye disease. Understanding why your eyes remain dry despite treatment is the first step toward lasting comfort and healthier vision.

Meibomian Gland Dysfunction (MGD)

One of the most common reasons artificial tears don’t provide lasting relief is Meibomian Gland Dysfunction (MGD). The meibomian glands, located along your eyelids, produce oils that prevent your tears from evaporating too quickly. When these glands become blocked or inflamed, the protective oil layer in your tear film breaks down, leading to evaporative dry eye.

Blepharitis

Blepharitis, or inflammation of the eyelids, is another common contributor to dry eye symptoms. This condition is often caused by bacteria, skin conditions like rosacea, or a buildup of debris along the lash line. Inflammation from blepharitis can affect the function of the meibomian glands, worsening dryness and irritation.

Eye Surgeries

Procedures such as LASIK, cataract surgery, or corneal transplants can temporarily or permanently affect the nerves responsible for tear production. When these nerves are disrupted, your eyes may not recognize dryness and signal for more tears to be produced. Post-surgical dry eye can persist for months or even longer, requiring specialized care beyond artificial tears.

Underlying Medical Conditions

Several medical conditions can cause or worsen dry eye disease. Autoimmune disorders like Sjögren’s syndrome, lupus, or rheumatoid arthritis often affect tear and oil gland function. Diabetes, thyroid disorders, and even hormonal changes (such as menopause) can also lead to chronic dryness. In these cases, addressing the underlying health condition in coordination with your eye doctor can make a significant difference in managing symptoms.
