Key Takeaways

  • Dry eye disease is one of the most common eye conditions and can affect people of all ages.
  • Symptoms may include burning, irritation, blurred vision, watery eyes and sensitivity to light.
  • Many cases are caused by poor tear quality rather than simply not producing enough tears.
  • Early diagnosis helps identify the underlying cause and allows treatment to be tailored to each patient.
  • Effective management often combines lifestyle changes, appropriate lubricating eye drops and professional eye care.

What Is Dry Eye Disease?

Dry eye disease is a common condition that occurs when your eyes do not produce enough healthy tears or when the tears evaporate too quickly. Although many people think dry eyes simply mean a lack of moisture, the condition is often more complex and can affect the quality of the tear film that protects the surface of the eye.

A healthy tear film is essential for keeping your eyes comfortable, maintaining clear vision and protecting the front surface of the eye. When this delicate balance is disrupted, everyday activities such as reading, driving, working on a computer or wearing contact lenses can become uncomfortable.

Dry eye disease can range from occasional mild irritation to persistent symptoms that affect quality of life. Fortunately, with the right diagnosis and personalised treatment, most people can achieve significant relief and better long-term eye comfort.

Dry Eye Disease Is More Common Than Many People Realise

Many people assume occasional burning or watery eyes are simply caused by tiredness, ageing or spending too much time in front of a screen. While these factors can contribute, they may also be early signs of dry eye disease.

The condition affects millions of people worldwide and has become increasingly common as our lifestyles have changed. Longer hours using computers, smartphones and other digital devices, along with air conditioning, heating and environmental factors, all place greater demands on the tear film.

Dry eye disease can affect adults of any age, although it becomes more common as we get older. Hormonal changes, certain medications, contact lens wear and some medical conditions can also increase the risk.

The good news is that modern eye care offers many effective ways to diagnose and manage dry eye disease. The first step is identifying the underlying cause rather than simply treating the symptoms.

Why Early Diagnosis Matters

Many people try different eye drops for months or even years without understanding why their eyes feel dry or irritated.

However, dry eye disease is not the same for everyone.

Some people produce too few tears, while others have tears that evaporate too quickly because of problems with the oil-producing glands in their eyelids, known as the meibomian glands.

Identifying the underlying cause allows your optometrist to recommend the most appropriate treatment, helping improve comfort, protect the surface of the eye and reduce ongoing irritation.

At First Choice Vision, every dry eye assessment begins with a comprehensive eye examination to understand your symptoms, evaluate your tear film and develop a personalised management plan based on your individual needs.

Regular comprehensive eye examinations are important not only for detecting dry eye disease, but also for identifying other eye conditions before they begin affecting your vision.

Common Symptoms of Dry Eye Disease

The symptoms of dry eye disease can vary from person to person. Some people experience only mild irritation, while others develop persistent discomfort that affects work, driving, reading and other daily activities.

Common symptoms include:

  • A dry, gritty or sandy sensation
  • Burning or stinging eyes
  • Redness
  • Watery eyes
  • Blurred vision that improves after blinking
  • Sensitivity to light
  • Eye fatigue
  • Itchy or irritated eyes
  • Stringy mucus around the eyes
  • Difficulty wearing contact lenses comfortably

Symptoms often become worse after prolonged screen use, reading, driving, exposure to air conditioning, heating or windy environments.

Why Do My Eyes Water If They Are Dry?

Many people are surprised when their eyes constantly water despite being diagnosed with dry eye disease.

This happens because irritated eyes can produce reflex tears. These tears are released quickly in response to irritation, but they are different from healthy tears that normally keep the eye comfortable.

Reflex tears provide temporary moisture but do not contain the balanced mixture of water, oils and mucus needed to maintain a stable tear film. As a result, the eyes may continue to feel dry even while they are watering.

This is one of the reasons why excessive tearing can actually be a symptom of dry eye disease, rather than the opposite.

What Causes Dry Eye Disease?

There is no single cause of dry eye disease. Instead, it usually develops because the tear film becomes unstable.

A healthy tear film has three important layers:

  • An oily layer, which slows tear evaporation.
  • A watery layer, which keeps the eye hydrated.
  • A mucus layer, which helps tears spread evenly across the surface of the eye.

When one or more of these layers is disrupted, the tears become less effective, leading to irritation, inflammation and discomfort.

Meibomian Gland Dysfunction (MGD)

One of the Most Common Causes of Dry Eye Disease

One of the leading causes of dry eye disease is Meibomian Gland Dysfunction (MGD).

The meibomian glands are tiny oil-producing glands located along the edges of the eyelids. Their job is to produce the oily layer of the tear film, which helps prevent tears from evaporating too quickly.

When these glands become blocked or stop functioning properly, the tear film becomes unstable and tears evaporate much faster than normal.

This condition is known as Meibomian Gland Dysfunction, or MGD, and is one of the most common causes of evaporative dry eye.

Symptoms of MGD

People with MGD may experience:

  • Burning eyes
  • Blurred vision that comes and goes
  • Red or irritated eyelids
  • Watery eyes
  • A gritty sensation
  • Eyes that feel tired at the end of the day
  • Difficulty wearing contact lenses

Because MGD develops gradually, many people assume these symptoms are simply part of ageing or screen use and do not seek professional advice until the discomfort becomes more noticeable.

Who Is More Likely to Develop Dry Eye Disease?

Several factors can increase the risk of developing dry eye disease, including:

  • Ageing
  • Hormonal changes, particularly after menopause
  • Extended screen use
  • Contact lens wear
  • Air conditioning or heating
  • Dry or windy environments
  • Certain medications, including some antihistamines and antidepressants
  • Autoimmune conditions such as Sjögren’s syndrome
  • Previous eye surgery
  • Meibomian Gland Dysfunction (MGD)

Having one or more of these risk factors does not necessarily mean you will develop dry eye disease, but they may increase your likelihood of experiencing symptoms.

Can Too Much Screen Time Cause Dry Eyes?

Digital devices have become a normal part of everyday life, but spending long periods looking at screens can contribute to dry eye disease.

When concentrating on a computer, tablet or smartphone, most people blink less frequently and often blink incompletely. This means the tear film is not spread evenly across the eye, allowing tears to evaporate more quickly.

Long hours of screen use can therefore lead to symptoms such as:

  • Dryness
  • Burning
  • Eye fatigue
  • Blurred vision
  • Watering eyes

A simple way to reduce digital eye strain is to follow the 20-20-20 Rule:

Every 20 minutes, look at something 20 feet (6 metres) away for at least 20 seconds.

Regular blinking and short breaks throughout the day can also help maintain a healthier tear film.

Is Dry Eye Disease Permanent?

Not always.

Some people experience temporary dry eye symptoms due to environmental factors or short-term lifestyle changes.

Others develop chronic dry eye disease that requires ongoing management.

The good news is that, even when dry eye disease cannot be permanently cured, effective treatment can significantly improve comfort, vision and quality of life.

The key is identifying the underlying cause and creating a personalised treatment plan rather than relying on eye drops alone.

Parent & Lifestyle Tip

If your eyes feel dry after a day on the computer, don’t automatically assume it’s simply because you’ve been working hard. Persistent dryness, burning or watering may be signs of dry eye disease and are worth discussing with your optometrist.

Maintaining healthy eyes involves more than treating dry eye symptoms. Regular eye examinations are also important for detecting other vision and eye health conditions early. You can also read our guide on Myopia in Children: Signs, Causes and Myopia Control Options to learn how regular eye care supports lifelong vision.

How Is Dry Eye Disease Diagnosed?

Although many people try over-the-counter eye drops when their eyes feel dry, diagnosing dry eye disease involves much more than confirming that your eyes are dry.

The first step is identifying why your symptoms are occurring.

During a comprehensive eye examination, your optometrist will discuss:

  • Your symptoms
  • When they started
  • How often they occur
  • Whether they worsen during screen use or at certain times of the day
  • Any medications you take
  • Your medical history
  • Contact lens wear
  • Previous eye surgery

Understanding your history helps determine whether your symptoms are related to dry eye disease, allergies, eyelid conditions or another eye problem.

What Does an Optometrist Check?

A dry eye assessment may include examining:

  • The quality and quantity of your tears
  • The stability of your tear film
  • Your eyelids and eyelashes
  • The meibomian glands
  • The front surface of the eye (cornea and conjunctiva)
  • Signs of inflammation or irritation

At First Choice Vision, we tailor every assessment to the individual patient rather than recommending the same treatment for everyone.

Because dry eye disease has many possible causes, identifying the underlying problem is one of the most important parts of successful treatment.

Why Over-the-Counter Eye Drops Don't Always Solve the Problem

Many people purchase lubricating eye drops expecting immediate and permanent relief.

While artificial tears can be very helpful, they do not treat every type of dry eye disease.

For example:

  • If your symptoms are caused by Meibomian Gland Dysfunction (MGD), lubricating drops alone may not address the blocked oil glands.
  • If an underlying eyelid condition or inflammation is contributing to your symptoms, additional treatment may be needed.
  • If environmental or lifestyle factors are responsible, simple daily habit changes may significantly improve comfort.

This is why identifying the underlying cause is so important before deciding on treatment.

Treatment Options for Dry Eye Disease

There is no single treatment that works for everyone.

The most effective management plan depends on the cause and severity of your dry eye disease.

Your optometrist may recommend one or more of the following approaches.

Artificial Tears

Artificial tears are often the first treatment recommended for mild to moderate dry eye disease.

They help lubricate the surface of the eye and temporarily improve comfort.

However, not all artificial tears are the same.

Different products are designed for different types of dry eye, and choosing the most appropriate option depends on your individual symptoms and the health of your tear film.

Using the wrong eye drops may provide only limited relief, which is why professional advice is valuable.

Warm Compresses

Warm compresses are commonly recommended for people with Meibomian Gland Dysfunction (MGD).

Applying gentle warmth to the eyelids may help soften thickened oils within the glands, improving their function and reducing tear evaporation.

For best results, warm compresses should be used consistently and according to your optometrist’s recommendations.

Eyelid Hygiene

Keeping the eyelids clean is another important part of managing some forms of dry eye disease.

Gentle eyelid cleansing may help remove debris, reduce inflammation and improve the function of the meibomian glands.

Your optometrist can recommend suitable eyelid hygiene products if they are appropriate for your condition.

Lifestyle Changes That Can Help

Simple lifestyle changes often play an important role in improving dry eye symptoms.

These may include:

  • Taking regular breaks during prolonged screen use.
  • Blinking fully and more frequently.
  • Staying well hydrated.
  • Avoiding direct air from fans or air conditioners.
  • Wearing sunglasses outdoors on windy days.
  • Increasing humidity in dry indoor environments where practical.

Although these changes may not eliminate dry eye disease, they often improve comfort and reduce symptom flare-ups.

Omega-3 Supplements: Do They Help?

Many people ask whether Omega-3 fatty acid supplements improve dry eye disease.

The scientific evidence is mixed.

Some studies have reported improvements in symptoms for certain patients, while others have shown little or no significant benefit.

For this reason, Omega-3 supplements should not be viewed as a universal solution for dry eye disease.

If you are considering supplements, discuss them with your optometrist or healthcare professional to determine whether they are appropriate for your individual circumstances.

Prescription Treatments

Some patients with moderate to severe dry eye disease may require prescription treatments.

Depending on the underlying cause, your optometrist may work with your general practitioner or ophthalmologist when additional medical treatment is required.

The most appropriate management plan depends on the severity of the condition, associated inflammation and the patient’s overall eye health.

Why Personalised Treatment Matters

One of the biggest misconceptions about dry eye disease is that everyone should receive the same treatment.

In reality, two people with similar symptoms may have completely different underlying causes.

For example:

  • One patient may have Meibomian Gland Dysfunction (MGD).
  • Another may produce insufficient tears.
  • Someone else may have symptoms related to medications or environmental factors.

Because of these differences, successful treatment begins with an accurate diagnosis rather than simply recommending eye drops.

At First Choice Vision, we believe every patient deserves a personalised management plan based on a comprehensive assessment and the latest evidence-based recommendations.

Quick Tip

If you’ve been using artificial tears for several weeks without noticeable improvement, it’s time for a comprehensive dry eye assessment. Persistent symptoms often indicate an underlying cause that requires more than lubricating eye drops alone.

Looking after your eyes involves more than treating existing symptoms. Regular eye examinations can also help detect other eye conditions before they begin affecting your vision. If you’re interested in learning more, read our article 10 Signs Your Child May Need an Eye Test: A Parent’s Guide.

FAQs

Your Most Common Questions Answered.

Can dry eye disease be cured?

Dry eye disease is often a long-term condition, but in many cases it can be successfully managed. The goal of treatment is to improve the quality and stability of the tear film, reduce symptoms and protect the surface of the eye. The most appropriate treatment depends on the underlying cause and should be tailored to each individual.

This is one of the most common symptoms of dry eye disease. When the surface of the eye becomes dry and irritated, the eyes may produce reflex tears. These watery tears do not contain the balanced components needed for a healthy tear film, so they often fail to provide lasting relief.

Yes. An unstable tear film can cause vision to fluctuate throughout the day. Many people notice that their vision becomes clearer after blinking because the tear film is temporarily redistributed across the surface of the eye.

Extended screen use can contribute to dry eye symptoms because people tend to blink less frequently while concentrating on digital devices. Taking regular breaks, blinking fully and adjusting your screen position may help reduce discomfort.

Many preservative-free artificial tears are suitable for regular use, but not all eye drops are the same. If you need to use lubricating eye drops frequently or your symptoms continue despite treatment, a comprehensive eye examination is recommended to identify the underlying cause.

Meibomian Gland Dysfunction (MGD) occurs when the oil-producing glands along the eyelid margins do not function properly. Because these oils help prevent tears from evaporating too quickly, MGD is one of the leading causes of evaporative dry eye disease.

You should arrange a comprehensive eye examination if you experience:

  • Persistent dryness
  • Burning or stinging
  • Excessive watering
  • Blurred vision
  • Red or irritated eyes
  • Difficulty wearing contact lenses
  • Symptoms that do not improve with over-the-counter lubricating drops

Early assessment helps identify the cause and allows treatment to begin before symptoms become more severe.

Some contact lens wearers experience increased dryness or discomfort, particularly after long periods of wear. Your optometrist can assess whether your symptoms are related to your contact lenses and recommend suitable alternatives or treatment options.
