Is Dry Eye a Sign of an Underlying Health Condition?

Dry eye is often associated with screen time, aging, or environmental irritation, but for some people, it may also signal a larger health issue. Chronic dryness, burning, fluctuating vision, or eye irritation can sometimes be related to underlying medical conditions that affect tear production, inflammation, or gland function. 

At Tres Vision Group in Melbourne and Brevard County, our board-certified eye doctors help identify the root causes of dry eye and develop personalized treatment plans for long-term relief.

How Dry Eye Develops

Healthy tears are made up of water, oils, and mucus that work together to keep the eye surface lubricated and stable. When the tear film becomes unbalanced — or when the eyes do not produce enough tears — patients may experience symptoms such as:

  • Burning or stinging
  • Redness
  • Grittiness or irritation
  • Blurry or fluctuating vision
  • Excessive tearing
  • Light sensitivity

While environmental triggers may contribute, persistent symptoms often require a closer evaluation.

Health Conditions Linked to Dry Eye

Several systemic health conditions are associated with chronic dry eye, including:

Autoimmune Disorders

Conditions such as Sjogren’s syndrome, rheumatoid arthritis, and lupus can affect the body’s moisture-producing glands, reducing tear production and causing significant dryness. Sjogren’s syndrome, in particular, is strongly linked to severe dry eye symptoms.

Diabetes

Diabetes can affect the nerves and glands responsible for maintaining a healthy tear film. Patients with diabetes may experience reduced tear production, corneal sensitivity changes, and chronic irritation.

Thyroid Disease

Certain thyroid disorders, especially autoimmune thyroid disease, may increase inflammation around the eyes and contribute to dryness and irritation.

Hormonal Changes

Hormonal fluctuations associated with menopause, pregnancy, or aging can alter tear composition and increase dry eye symptoms. This is one reason dry eye becomes more common after age 40.

Medications Can Also Play a Role

Some commonly used medications may reduce tear production, including:

  • Antihistamines
  • Decongestants
  • Antidepressants
  • Blood pressure medications
  • Acne medications

If dry eye develops after starting a new medication, your eye doctor can help determine whether it may be contributing to symptoms.

Why Proper Diagnosis Matters

Not all dry eye is the same. Some patients primarily have aqueous-deficient dry eye, while others have evaporative dry eye caused by meibomian gland dysfunction (MGD). Identifying the underlying cause allows for more effective treatment and better long-term symptom control.

At Tres Vision Group, advanced diagnostic testing helps evaluate tear quality, gland function, and ocular surface health to create targeted treatment plans.
