Dry eye, also known as dry eye syndrome (DES) or keratoconjunctivitis sicca, is a common condition where your eyes don’t produce enough tears or the quality of tears is poor. This can lead to discomfort, vision problems, and potential damage to the eye’s surface. Millions of people worldwide suffer from dry eye, making it a significant public health concern.

What Causes Dry Eye?

Dry eye occurs when the tear film, which keeps the eyes moist, is disrupted. The tear film has three layers: oil, water, and mucus. Issues with any layer can lead to dryness.

Common Causes:

• Aging: Tear production decreases with age, especially after 50. Learn more about dry eye problems
• Environmental factors: Wind, smoke, air conditioning, and prolonged screen time can dry out eyes.
• Medications: Antihistamines, antidepressants, and certain blood pressure drugs may reduce tear production. Check dry eye medications
• Medical conditions: Autoimmune diseases like Sjögren’s syndrome, rheumatoid arthritis, and diabetes are linked to dry eye.
• Eye surgeries: Procedures like LASIK and dry eye or cataract surgery can temporarily or permanently affect tear production.
• Hormonal changes: Pregnancy, menopause, and birth control pills can influence tear production.

Symptoms of Dry Eye

The symptoms of dry eye can range from mild discomfort to severe vision problems, significantly impacting daily activities. Recognizing these symptoms early can lead to prompt treatment and better outcomes.

People with dry eye often report:

• Burning or stinging sensations: A constant feeling of burning in the eyes can make focusing difficult.
• Redness and irritation: Inflamed eyes may appear bloodshot, especially after extended periods of reading or screen time.
• Blurred vision: Vision may fluctuate, becoming worse after prolonged concentration.
• Sensitivity to light: Photophobia is common, making outdoor activities uncomfortable.
• Foreign body sensation: Many describe the feeling as if there’s grit or sand in the eyes.
• Excessive tearing: Ironically, dry eyes can cause overproduction of poor-quality tears in response to irritation.
• Difficulty wearing contact lenses: Dryness can cause discomfort, making contact lens use challenging.

Tip: If you experience any of these symptoms consistently, seek evaluation from an eye care professional for an accurate diagnosis and tailored treatment plan.

How Is Dry Eye Diagnosed?

Accurate diagnosis of dry eye is crucial to identify the underlying cause and determine the best treatment approach. Eye care professionals use various methods to evaluate tear production, quality, and the health of the ocular surface. A comprehensive examination often includes patient history, symptom questionnaires, and specialized tests.

Common Diagnostic Tests Explained:

• Schirmer’s Test: This test measures tear production using a small strip of filter paper placed under the lower eyelid. The patient keeps their eyes closed for five minutes, and the amount of moisture absorbed indicates tear production levels. Low readings suggest aqueous tear deficiency, a common cause of dry eye.
• Tear Break-Up Time (TBUT): Fluorescein dye is instilled into the eye to observe how long the tear film remains stable before breaking up. A short TBUT (less than 10 seconds) indicates tear film instability, a hallmark of evaporative dry eye.
• Ocular Surface Staining: Dyes such as fluorescein or lissamine green are used to highlight damaged or dry areas on the cornea and conjunctiva. The extent and pattern of staining help assess the severity of dry eye and monitor treatment progress.
• Meibomian Gland Evaluation: The meibomian glands, located in the eyelids, produce the oily layer of the tear film. Dysfunction of these glands (meibomian gland dysfunction or MGD) is a leading cause of evaporative dry eye. Doctors may gently express the glands or use imaging technology to assess blockages or gland loss. Learn about meibomian gland treatments
• Tear Osmolarity Test: This test measures the salt concentration in tears. High osmolarity indicates inflammation and poor tear quality, both common in chronic dry eye.
• Inflammatory Marker Testing: Some clinics use advanced tests to detect markers of inflammation in the tear film, helping to guide anti-inflammatory treatments.

Understanding the specific type of dry eye—aqueous-deficient, evaporative, or a combination—allows healthcare providers to tailor the most effective treatment plan for each patient. Regular follow-ups ensure that therapies are working and adjustments can be made as needed.

See treatment options for dry eye## Who Is at Risk for Dry Eye? Dry eye can affect anyone, but certain groups are more vulnerable. Understanding your risk factors can guide prevention and early intervention.

High-Risk Groups:

• Adults over 50: Tear production diminishes naturally with age, making older individuals more susceptible.
• Women: Hormonal changes during menopause, pregnancy, or with contraceptive use increase risk.
• Contact lens users: Long-term lens wear can interfere with tear production and distribution.
• Digital device users: Prolonged screen time reduces blink frequency, leading to tear evaporation.
• Outdoor workers: Exposure to wind, sun, and dry climates accelerates tear evaporation.
• Individuals with autoimmune diseases: Conditions like lupus or rheumatoid arthritis can affect the tear glands.

Complications of Untreated Dry Eye

Ignoring dry eye symptoms can lead to significant complications affecting both vision and overall eye health. While mild cases may seem like a minor inconvenience, chronic or untreated dry eye can cause progressive damage to the ocular surface, leading to long-term issues.

Potential Complications:

• Eye infections: Tears play a vital role in protecting the eyes from harmful bacteria and debris. Insufficient tear production compromises this defense, making the eyes more susceptible to infections like bacterial conjunctivitis and keratitis.
• Corneal damage: Persistent dryness can lead to the development of corneal abrasions, ulcers, and thinning of the corneal tissue. In severe cases, these complications can result in scarring that impairs vision permanently.
• Impaired daily activities: Everyday tasks such as reading, driving (especially at night), and using digital devices become increasingly difficult with chronic dry eye. This can significantly hinder productivity at work and affect quality of life.
• Sensitivity to light and fluctuating vision: Photophobia (light sensitivity) and blurred vision can become constant problems, impacting activities like outdoor recreation or working in bright environments.
• Reduced quality of life: The constant discomfort, visual disturbances, and frustration associated with untreated dry eye can lead to anxiety, decreased social engagement, and even depression.
• Potential for vision loss: Although rare, severe and untreated cases of dry eye can cause irreversible vision loss due to corneal complications and infections.

Early diagnosis and appropriate treatment are essential to prevent these complications. Ignoring symptoms or delaying care can make treatment more challenging and less effective over time. By working closely with an eye care provider, most patients can manage symptoms and avoid long-term damage.

• Persistent redness or irritation: These symptoms may signal underlying inflammation or infection.
• Sudden vision changes: Blurred or fluctuating vision should never be ignored.
• Eye pain or sensitivity to light: Severe symptoms warrant immediate attention.
• Ineffectiveness of over-the-counter solutions: Professional evaluation can identify causes requiring prescription treatments.
