Dry Eye & Tear Health: Causes, Care & Relief

If your eyes frequently feel scratchy, gritty, or tired by midday or if they water excessively for no clear reason, you could be experiencing dry eye syndrome, a surprisingly common condition that impacts millions of people worldwide. It happens when your eyes don’t produce enough tears, or when the tears you do make lack the right balance of water, oil, and mucus to keep them stable.

While it might seem like a minor annoyance, healthy tears are the eyes’ built-in defense system, they keep your vision clear, shield against dust and bacteria, and prevent irritation from everyday environmental stressors. Without good tear health, even simple tasks like reading, driving, or working on a computer can become uncomfortable or blurry.

In this guide, we’ll take a closer look at why dry eyes happen, the subtle signs you might be overlooking, and proven strategies to boost tear quality and quantity. From quick at-home remedies to advanced medical treatments, you’ll discover how to keep your eyes comfortably hydrated, protecting your vision and overall eye wellness for years to come.

Understanding Dry Eye and Tear Health

What Is Dry Eye Syndrome?

Dry eye syndrome occurs when your eyes can’t produce enough tears or when the tears you do produce evaporate too quickly—leaving the surface of your eye exposed and unprotected. While many people imagine tears as simply water, they’re actually a carefully balanced mixture of three layers:

• A watery layer that hydrates and nourishes the eye’s surface.

• An oily layer that slows evaporation and keeps the tear film stable.

• A mucus layer that helps spread tears evenly across the cornea.

When any of these layers is missing or out of balance, your eyes can feel dry, itchy, gritty, or overly watery (yes, watering can be a sign of dryness, as your eyes try to compensate). This imbalance can be caused by environmental factors, health conditions, aging, or even lifestyle habits like extended screen use.

Why Tear Health Matters for Vision

Think of healthy tears as your eye’s natural defense system—like a transparent shield that protects your vision. Tears constantly bathe the cornea, washing away dust, debris, and microorganisms while keeping the surface smooth for sharp, clear sight. Without a stable tear film:

• The cornea can become irritated, red, and inflamed.

• You may be more vulnerable to eye infections.

• Persistent dryness can lead to microscopic damage, and in severe cases, scarring of the cornea.

Over time, poor tear health can cause fluctuating or blurred vision, light sensitivity, and chronic discomfort that affects daily life—from reading and driving to simply enjoying the outdoors. Protecting your tear health isn’t just about comfort—it’s essential for long-term eye wellness and preserving clear vision.

Common Causes of Dry Eye

Environmental Factors

Your surroundings can play a big role in how well your eyes stay hydrated. Common culprits include:

• Low-humidity environments — Air-conditioned offices, heated indoor spaces in winter, or long flights can quickly dry out your tear film.

• Windy or dusty conditions — Outdoor activities like cycling, hiking, or gardening can expose your eyes to drying air currents and airborne particles.

• Prolonged screen time — When using computers, phones, or tablets, we tend to blink less—sometimes up to 60% less—which allows tears to evaporate more quickly and leaves the eyes feeling gritty or tired.

Health Conditions & Medications

Certain medical conditions can directly impact tear production or the quality of your tears. These include:

• Autoimmune disorders such as Sjögren’s syndrome, lupus, or rheumatoid arthritis.

• Chronic illnesses like diabetes or thyroid disease.

• Eye-related conditions such as blepharitis (eyelid inflammation).

Medications can also be a hidden cause of dry eye, including:

• Antihistamines for allergies

• Antidepressants

• Some blood pressure medications (like beta-blockers or diuretics)

These drugs may reduce tear production as a side effect, so it’s worth discussing alternatives with your healthcare provider if dryness becomes an issue.

Aging and Hormonal Changes

As we age, our tear glands naturally produce fewer tears. This process can start as early as our 40s and becomes more noticeable over time. Hormonal changes—especially during menopause—can also alter the composition of tears, making them less stable and more prone to evaporation. Women are statistically more likely to experience chronic dry eye due to these hormonal shifts.

Symptoms to Watch For

Early Signs

• Burning or stinging sensation

• Redness

• Sensitivity to light

• Feeling like something is in your eye

When to See a Doctor

Occasional eye dryness from wind, weather, or long hours at a computer is common but persistent symptoms should never be ignored. You should schedule an eye exam if:

• Dryness, burning, or irritation lasts longer than a week despite using over-the-counter artificial tears.

• Symptoms interfere with daily activities, such as reading, driving, or working on screens.

• You experience sudden vision changes, increased light sensitivity, or unexplained eye pain.

• There’s excessive redness, swelling, or discharge, which could signal infection or inflammation.

Seeing an eye care professional early can prevent long-term complications like corneal damage or chronic inflammation. Your doctor can perform specialized tests to measure tear quantity and quality, pinpoint the cause, and recommend treatments from medicated drops to procedures that help your eyes retain moisture.

Tip: Keep a diary of your symptoms, including when they occur and possible triggers. This information can help your doctor make a faster, more accurate diagnosis.

How to Improve Tear Health

Hydration and Nutrition

• Drink enough water daily—aim for at least 8 cups.

• Include omega-3 fatty acids (from salmon, flaxseed, chia seeds) to support tear film stability.

• Eat antioxidant-rich foods like leafy greens and berries for overall eye health.

Lifestyle Adjustments

• Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.

• Avoid smoking and limit alcohol intake, as both can dehydrate your eyes.

• Use a humidifier to maintain indoor air moisture.

Home Remedies for Eye Comfort

• Warm compresses on the eyes can stimulate oil glands.

• Blink fully and frequently, especially when on screens.

• Wear wraparound sunglasses outdoors to protect from wind and UV rays.

Medical Treatments for Dry Eye

While lifestyle changes and home remedies can help mild dry eye symptoms, some cases require professional treatment to restore tear health and prevent long-term damage. Here are the most common medical options:

Artificial Tears & Lubricating Gels

For many people, over-the-counter artificial tears are the first line of defense. These drops supplement your natural tear film, helping to reduce irritation and improve comfort.

• Artificial tears are lightweight and can be used several times a day.

• Lubricating gels or ointments are thicker and stay on the eye longer, making them ideal for overnight relief or more severe dryness.

Tip: Look for preservative-free formulas if you use them frequently, as preservatives can cause irritation over time.

Prescription Medications

If over-the-counter products aren’t enough, your eye doctor may recommend:

• Anti-inflammatory eye drops such as cyclosporine (Restasis) or lifitegrast (Xiidra) to reduce inflammation in the tear glands and improve natural tear production.

• Secretagogues, oral medications that stimulate the tear glands to produce more fluid.

• Short courses of steroid eye drops to quickly calm inflammation (typically used only under close supervision).

Procedures to Increase Tear Retention

In cases where tears drain away too quickly, your doctor might suggest:

• Punctal plugs — tiny biocompatible devices inserted into the tear ducts to slow tear drainage, keeping moisture on the eye’s surface longer.

• Thermal or light-based treatments — such as intense pulsed light (IPL) therapy, which targets blocked oil glands in the eyelids to improve tear film stability.

By combining these treatments with healthy eye habits, many patients experience significant relief and a noticeable improvement in vision comfort.

Preventing Chronic Dry Eye

Workplace Eye Care

Many people spend 6–10 hours a day in front of screens, which can significantly reduce blink frequency and speed up tear evaporation. To protect your eyes at work:

• Adjust your screen position — Place your monitor slightly below eye level so your eyelids naturally cover more of the eye surface, reducing moisture loss.

• Follow the 20-20-20 rule — Every 20 minutes, look at something at least 20 feet away for 20 seconds to reset your blinking pattern and give your eyes a break.

• Use artificial tears during long tasks — Especially in air-conditioned or heated offices where the air is drier.

Seasonal Eye Protection

Changes in weather and indoor environments can affect tear stability year-round:

• Winter dryness — Indoor heating systems can drop humidity to desert-like levels. Running a humidifier in your workspace or bedroom adds moisture to the air and helps keep your eyes from drying out.

• Summer and outdoor protection — Intense sunlight, wind, and dust can strip away your tear film. Wearing wraparound sunglasses or protective goggles during outdoor activities shields your eyes from UV rays and prevents moisture loss.

Pro tip: Keep a small bottle of preservative-free artificial tears in your bag or desk drawer so relief is always within reach no matter the season.

FAQs About Dry Eye & Tear Health

1. Can dry eye syndrome go away on its own?

In some cases, yes if the cause is temporary, like wind exposure or seasonal allergies, your eyes may recover once the trigger is removed. However, if dry eye is caused by chronic conditions (such as hormonal changes, autoimmune disease, or long-term medication use), it usually requires ongoing management. Early intervention helps prevent damage to the cornea and improves overall comfort.

2. Why do my eyes water if I have dry eye?

It might seem strange, but excessive tearing can actually be a symptom of dry eye. When your tear film is unstable, the eye surface becomes irritated. In response, your tear glands may produce a flood of watery tears—but without the oily and mucous components needed to keep them in place, they evaporate quickly and don’t provide lasting relief.

3. Are there vitamins or supplements that help with tear health?

Yes. Omega-3 fatty acids (found in fish oil, flaxseed, and chia seeds) can help improve the oily layer of tears, reducing evaporation. Vitamin A supports the surface tissues of the eye, while antioxidants like vitamin C, vitamin E, and lutein can protect against oxidative stress that may worsen dryness. Always check with your doctor before starting new supplements—especially if you have existing health conditions.

4. How can I prevent dry eye if I work at a computer all day?

Follow the 20-20-20 rule—every 20 minutes, look at something 20 feet away for at least 20 seconds. Position your screen slightly below eye level so your eyelids cover more of your eye surface. Keep a bottle of preservative-free artificial tears at your desk, and use a humidifier in dry office environments. Regular blinking exercises can also help maintain a healthy tear film.

5. What treatments are available if artificial tears don’t work?

If over-the-counter drops aren’t enough, an eye doctor can recommend:

• Prescription anti-inflammatory eye drops (e.g., cyclosporine or lifitegrast) to improve tear production.

• Punctal plugs to slow tear drainage.

• Thermal or light-based therapies to unclog oil glands in the eyelids.

• Oral medications that stimulate tear secretion.
  Treatment choice depends on the root cause of your dry eye, so professional evaluation is essential.
