What Are the Main Causes of Dry Eye? Long-Term Prevention Tips and Options for Relief That Lasts

Dry eye is a common condition that affects millions of people, causing discomfort, irritation, and even vision problems. While occasional dryness may be a minor nuisance, chronic dry eye can significantly impact daily life. Understanding the main causes of dry eye and how to prevent and treat it effectively can help you maintain long-term relief and eye health.


What Is Dry Eye?

Dry eye occurs when the eyes do not produce enough tears or when the quality of tears is poor, leading to inadequate lubrication. This condition can cause symptoms such as:
 

  • A gritty or burning sensation in the eyes

  • Redness and irritation

  • Blurred vision

  • Sensitivity to light

  • Watery eyes
     

Tears play a crucial role in protecting the eyes and maintaining clear vision. When tear production or quality is compromised, discomfort and potential complications can arise.


What Are the Main Causes of Dry Eye?

The meibomian glands, located along the edges of the eyelids, produce the oily layer of tears that prevents rapid evaporation. When these glands become blocked or do not function properly, tears evaporate too quickly, leading to dryness. MGD is one of the leading causes of chronic dry eye and is often associated with conditions such as rosacea.
 

Blepharitis is inflammation of the eyelids, often caused by bacteria or clogged oil glands. This condition can lead to irritated, swollen eyelids and disrupt the tear film, resulting in dry eye symptoms. People with blepharitis may also experience crusting along the lash line, itching, and redness.
 

Additional factors that contribute to dry eye include:
 

  • Aging – Tear production decreases with age, particularly in individuals over 50.

  • Environmental conditions – Wind, smoke, air conditioning, and screen time can contribute to tear evaporation.

  • Medications – Antihistamines, decongestants, antidepressants, and blood pressure medications can reduce tear production.

  • Autoimmune diseases – Conditions like Sjögren’s syndrome, rheumatoid arthritis, and lupus can impair tear gland function.

  • Contact lenses – Long-term contact lens use can interfere with the natural tear film.

  • Hormonal changes – Pregnancy, menopause, and hormone replacement therapy can affect tear production.


Tips for Prevention

While some causes of dry eye are unavoidable, there are steps you can take to reduce the risk and manage symptoms:
 

  • Stay hydrated – Drink plenty of water to support tear production.

  • Blink frequently – Conscious blinking helps distribute tears evenly and prevents evaporation.

  • Use a humidifier – Adding moisture to the air can prevent tears from drying too quickly.

  • Wear protective eyewear – Sunglasses with wraparound frames can shield eyes from wind and dry air.


When to See an Eye Doctor

If dry eye symptoms persist despite home remedies, it’s time to see Dr. LaTandra Blue. A professional evaluation can help determine the underlying cause and recommend an effective treatment plan.
 

Regular eyelid hygiene, such as using a warm compress and gentle lid scrubs, helps keep oil glands clear and reduces inflammation. Over-the-counter artificial tears can provide temporary relief by supplementing natural tear production, with preservative-free options recommended for frequent use.
 

For chronic cases, prescription eye drops can help increase tear production and reduce inflammation. Additionally, nutritional supplements, particularly omega-3 fatty acids found in fish oil and flaxseed, may support tear quality by reducing inflammation and promoting healthy oil gland function.
