Living with dry eyes can be more than just a minor annoyance; it can disrupt your day-to-day life. Below, we examine the causes, impacts, prevention measures, and treatments for the common condition known as dry eye disease.

Precursor of Dry Eyes: Tear Film Dysfunction

Understanding Tear Film

Your eyes are your window to the world, and like any window, they need to be well-lubricated to work effectively. Within your eyes is a tear film composed of fatty oils, aqueous fluid, and mucus. This trio combines to keep your eyes lubricated, smooth, and clear.

The Reasons Behind Tear Film Dysfunction

Tear film dysfunction, leading to dry eyes, derives from numerous causal factors. Key reasons essential to understand are:

  • Hormone changes: Shifts in hormonal balance significantly impact tear film stability and may induce dry eyes.
  • Autoimmune diseases: Disorders such as Sjögren’s syndrome, lupus, and rheumatoid arthritis disrupt tear production, causing dry eyes.
  • Allergic eye disease: Allergies often cause eyes to dry out, exacerbating tear film dysfunction.

Decreased Tear Production: A Leading Cause of Dry Eyes

The Role of Aging and Certain Medical Conditions

One of the most common causes of dry eyes is decreased tear production. This can result from aging or certain medical conditions such as Sjogren’s syndrome, rheumatoid arthritis, and lupus, among others. An optometrist can diagnose these conditions and suggest appropriate eye care services.

The Impact of Medicines on Tear Production

Medications largely impact natural tear production. Certain drugs contribute to dry eye conditions more than others, reducing tear production. Key culprits include:

  • High blood pressure medicines
  • Acne medications
  • Birth control pills
  • Parkinson’s disease drugs

These drugs can disrupt the balance of tear production, resulting in dry eyes and discomfort.

Tear Evaporation: Another Culprit of Dry Eyes

Blocked Meibomian Glands and Its Effects

Blocked meibomian glands can result in increased tear evaporation, contributing significantly to dry eyes. Excellent patient care at your local eye care clinic can help effectively address this problem. If you’re in Indiana, consider consulting eye doctors in Bloomington, Indiana, for assistance.

How Certain Environments and Habits Influence Tear Evaporation

Various environmental factors and habits can inadvertently exacerbate tear evaporation. These include:

  • Wind: Exposure to windy conditions, especially when outdoors, can increase the rate of tear evaporation.
  • Dry Air: Areas with dry air, such as air-conditioned rooms or high-altitude regions, can lead to quicker evaporation of tears.
  • Less Blinking Activities: Concentrated tasks like reading or working on a computer often lead to reduced blinking, which promotes tear evaporation and contributes to dry eyes.

Dry Eyes and Its Impact on Quality of Life

Risks and Complications of Untreated Dry Eyes

If left untreated, dry eyes can have serious consequences, not just for your vision but, more broadly, your quality of life. Certain risks and complications include:

  • Eye infections: Dry eyes can make you more prone to microbial infections.
  • Abrasion of the corneal surface: Without adequate lubrication, the friction caused by blinking can damage the cornea.
  • Corneal ulcers: In extreme cases, dry eyes can lead to painful and sight-threatening corneal ulcers.
  • Decreased quality of life: Persistent dry eyes can hamper daily activities and lead to considerable discomfort.

How Dry Eyes Affect Everyday Life

Living with dry eyes can influence your daily routine and activities. While it presents a health risk, its impact goes beyond the physical. Here’s how:

  • Reading: Dry eyes can make prolonged reading uncomfortable and fatigue your eyes quickly.
  • Night Driving: It can affect your nocturnal vision, making night driving unsafe.
  • Screen time: Spending extended periods on the computer can intensify dry eye symptoms, causing discomfort.

These interferences can significantly affect job productivity and overall life quality. Therefore, appropriate treatment is essential to keep dry eyes under control.

Preventing Dry Eyes: Practical Measures

Tips to Avoid Dry Eyes Triggers

Combatting dry eyes often involves modifying certain habits and environmental factors. Here are brief, practical measures you can adopt:

  1. Avoid exposure to direct air, especially from fans and air conditioners.
  2. In dry climates or winter months, use humidifiers to add moisture to indoor air.
  3. Protect your eyes outdoors with wraparound sunglasses or wind-resistant eyewear.
  4. Practice frequent blinking, especially during prolonged screen time, to aid natural eye lubrication.

Treatment Options for Dry Eyes

Lifestyle Changes that Combat Dry Eyes

Besides prevention, certain lifestyle changes can also treat dry eyes. Posture adjustment to position your computer screen below eye level or taking eye breaks during long tasks are effective ways to manage dry eyes. It’s also worth trying to quit or avoid tobacco smoke, which can exacerbate dry eyes.

Eye Drops and Over the Counter Solutions

Eye drops for dry eyes, also known as artificial tears, are commonly used to keep them well-lubricated and comfortable. For chronic dry eyes, regular use of these drops is recommended. In extreme cases, your eye doctor may suggest a dry eye therapy to best manage the condition based on its cause and severity.


With the right measures, dry eyes can significantly be managed. Understanding what triggers dry eyes, taking appropriate prevention measures, and using effective treatments are key to improving eye comfort and quality of life. Whether you are battling fluctuating vision, tear film instability, or age-related dry eyes, help is available to regain your eye health.
