Watery eyes can be frustrating. They can blur vision, interrupt daily activities and leave you wondering why your eyes seem to be producing tears constantly.

While occasional watering is completely normal, eyes that repeatedly stream or overflow may be trying to tell you something. What seems like a simple nuisance is often a sign that the eye’s delicate balance has been disrupted.

Understanding the common causes of watery eyes can help you recognise when symptoms are likely to settle on their own and when it may be worth seeking professional advice.

At Vision Care Clinic, we assess and treat a wide range of eye conditions, including dry eye disease, which, perhaps surprisingly, is one of the most common reasons behind persistently watery eyes.

Why Do Our Eyes Water?

Tears are essential for healthy, comfortable vision. They lubricate the surface of the eye, help wash away debris and provide protection against infection.
Under normal circumstances, tears drain away through tiny openings in the inner corners of the eyelids before passing into the tear drainage system.

Watery eyes usually occur for one of two reasons:
• Your eyes are producing more tears than usual.
• Tears are unable to drain away effectively.

The key question is often not, “Why are my eyes watering?” but rather, “What is causing my eyes to produce or retain these excess tears?”

Dry Eye Disease

This is often the answer patients least expect.

It may seem contradictory, but dry eye disease is one of the most common causes of watery eyes.

When the surface of the eye becomes dry or irritated, the eye responds by producing a sudden surge of reflex tears. The problem is that these tears are largely watery and may not contain the right balance of oils and other components needed to properly nourish and protect the eye.

As a result, the cycle continues. The eye remains irritated, triggering more tears, while still feeling dry, gritty or uncomfortable.

Many patients are surprised to discover that their watery eyes are actually a symptom of underlying dryness rather than excessive tear production alone.

Blocked Tear Ducts

Sometimes the eyes are producing a normal amount of tears, but the drainage system is not working as efficiently as it should.

If the tear ducts become narrowed or blocked, tears can collect on the surface of the eye and spill over onto the cheeks.

This can occur as a result of inflammation, infection, previous injury or age-related changes to the drainage system.

Persistent watering in one eye, particularly without other symptoms, can sometimes point towards a tear drainage problem.

Allergies

Allergies are another common cause of watery eyes.

Pollen, dust mites, pet dander and other allergens can irritate the eyes and trigger increased tear production as part of the body’s natural defence response.
If allergies are responsible, watering is often accompanied by:
• Itching
• Redness
• Swollen eyelids
• A burning sensation

You may also notice symptoms worsening during certain seasons or in specific environments.

Blepharitis

Blepharitis is a common condition that causes inflammation along the eyelid margins.

The condition can affect the tiny glands that produce the oily layer of the tear film. When this oil layer becomes unstable, tears evaporate more quickly, leading to irritation and dryness.

In response, the eyes may begin watering excessively.

Patients with blepharitis often describe a combination of watering, irritation, crusting around the lashes and a gritty sensation.

Environmental Irritation

Sometimes the explanation is much simpler.

Wind, smoke, pollution, cold weather and bright sunlight can all temporarily stimulate the eyes to produce additional tears.

Modern lifestyles can also contribute. When we focus on digital screens, we tend to blink less frequently. This allows tears to evaporate more quickly, potentially leading to dryness, irritation and reflex watering.

If your symptoms seem worse after long periods of computer use, your screen habits could be playing a role.

Something in the Eye

The eye has a highly effective protective mechanism.
An eyelash, a speck of dust or another small foreign body can quickly trigger increased tear production as the eye attempts to flush the irritant away.

Minor irritation often settles naturally. However, if discomfort, redness or watering persists, it is sensible to have the eye examined to ensure nothing remains on the surface.

When Should You Seek Advice?

Occasional watery eyes are usually not a cause for concern.
However, it may be worth arranging an eye examination if your symptoms are:

• Persistent
• Becoming more frequent
• Affecting your vision
• Accompanied by pain
• Associated with significant redness
• Linked to changes in your eyesight

The sooner the underlying cause is identified, the sooner appropriate treatment can begin.
