What Are the Common Symptoms of Dry Eye Disease?

Dry eye disease is one of the most common eye conditions, yet many people don't realise they have it. While the name suggests a simple lack of tears, dry eye is often caused by an unstable tear film or poor-quality tears that evaporate too quickly.

Symptoms can vary throughout the day and often become worse when reading, using digital devices, driving or spending time in air-conditioned environments.

Recognising the symptoms early can help prevent the condition from progressing and allow treatment to target the underlying cause.

1. Burning or Stinging Eyes

One of the most common symptoms of dry eye disease is a burning or stinging sensation.

This occurs because the surface of the eye is no longer adequately protected by a healthy tear film, allowing it to become irritated.

2. A Gritty or Sandy Feeling

Many patients describe it as feeling as though there is sand or grit trapped in their eyes.

Even though nothing is physically present, inflammation and tear film instability can create this uncomfortable sensation.

3. Watery Eyes

It may seem surprising, but excessive watering is actually one of the most common symptoms of dry eye disease.

When the surface of the eye becomes irritated, it produces reflex tears. These tears are mostly water and lack the oil layer needed to remain on the eye, so they often provide little lasting relief.

4. Blurred or Fluctuating Vision

If your vision becomes blurry but clears after blinking, dry eye may be the cause.

An unstable tear film prevents light from focusing consistently, causing vision to fluctuate throughout the day.

Many people mistakenly think they need stronger glasses when the real problem is the tear film.

5. Red Eyes

Inflammation associated with dry eye disease often causes the eyes to appear red or bloodshot.

Persistent redness should always be assessed to identify the underlying cause.

6. Light Sensitivity

A healthy tear film helps protect the sensitive surface of the eye.

When that protection is compromised, bright lights, sunlight or headlights at night may become uncomfortable.

7. Tired or Heavy Eyes

Patients frequently describe their eyes as feeling tired, heavy or fatigued, particularly towards the end of the working day.

This is especially common in people who spend long periods using computers or other digital devices.

8. Contact Lens Discomfort

If you've always been able to wear contact lenses comfortably but suddenly struggle to tolerate them, dry eye disease may be responsible.

Reduced tear quality can make lenses feel dry, uncomfortable or unstable.

9. Stringy Mucus Around the Eyes

Some people notice sticky or stringy mucus around their eyes, particularly on waking.

This can occur when inflammation affects the normal balance of the tear film.

10. Difficulty Keeping Your Eyes Open

Severe dry eye can make it difficult to keep your eyes comfortably open, particularly in windy conditions, air conditioning or heated environments.

Many patients instinctively close their eyes because doing so provides temporary relief.

Why Do These Symptoms Occur?

In many cases, the underlying problem is Meibomian Gland Dysfunction (MGD).

The meibomian glands produce the oil layer of the tear film. When these glands become blocked or stop functioning properly, tears evaporate too quickly, leading to irritation and inflammation.

Other causes of dry eye disease include:

• Blepharitis

• Demodex mites

• Hormonal changes, particularly during menopause

• Rosacea

• Autoimmune conditions such as Sjögren's syndrome

• Certain medications

• Long periods of screen use

• Environmental factors such as wind and air conditioning

Why Eye Drops Aren't Always Enough

Many people rely on lubricating eye drops to relieve their symptoms.

While drops can provide temporary comfort, they don't always address the underlying cause of dry eye disease.

A specialist assessment can identify whether your symptoms are caused by meibomian gland dysfunction, blepharitis, inflammation or another underlying condition, allowing treatment to be tailored accordingly.

When Should You Book an Assessment?

You should consider a specialist dry eye assessment if:

• Your symptoms persist despite using eye drops.

• Your vision fluctuates throughout the day.

• Your eyes frequently water.

• You experience burning, grittiness or discomfort.

• Contact lenses have become uncomfortable.

• Your symptoms are affecting your quality of life.

Early diagnosis is important because untreated dry eye disease can lead to progressive meibomian gland dysfunction, and once glands are permanently lost, they cannot currently be restored.
