Why Do My Eyes Water When They’re Dry?

Written By Alexa Hecht

A guide from your Forest Hill optometrist

If your eyes constantly water, you might assume the problem is too many tears. But in many cases, the opposite is true. Excess tearing is often a sign of dry eye syndrome, a common condition we see in patients at our Forest Hill optometry clinic.

While it may sound contradictory, dry eyes can actually trigger your eyes to produce more tears than usual. Understanding why this happens can help you find the right treatment and finally get relief.

Why Dry Eyes Can Cause Watery Eyes

Your tears play an important role in keeping your eyes healthy. A healthy tear film contains three layers:

  • Oil layer – prevents tears from evaporating too quickly

  • Water layer – hydrates the eye surface

  • Mucus layer – helps tears spread evenly across the eye

When this balance is disrupted, your eyes may become irritated and dry. In response, your body produces reflex tears, which are the watery tears that cause your eyes to overflow.

These reflex tears don’t contain the proper balance of oils and mucus needed to properly lubricate your eyes, so they don’t actually solve the dryness.

Instead, they often lead to a frustrating cycle of dryness, irritation, and watering.

Common Symptoms of Dry Eye

Many people are surprised to learn that watery eyes are one of the most common signs of dry eye syndrome.

Other symptoms may include:

  • Burning or stinging eyes

  • Redness or irritation

  • A gritty or sandy feeling in the eyes

  • Blurred vision that improves when you blink

  • Sensitivity to light

  • Eye fatigue, especially when reading or using screens

Dry eye symptoms can range from mild to severe and may fluctuate throughout the day.

Why Dry Eye Is So Common in Toronto

Dry eye is especially common in urban environments like Toronto, where several lifestyle and environmental factors contribute to the condition.

Some common triggers include:

Screen Use

Many people spend hours on computers, phones, or tablets. When focusing on screens, we tend to blink less frequently, which allows tears to evaporate faster.

Indoor Heating and Air Conditioning

Toronto’s winters require constant heating, while summers often involve air conditioning. Both can dry out the air, leading to faster tear evaporation.

Contact Lens Wear

Contact lenses can sometimes contribute to dryness by affecting the tear film.

Aging

Dry eye becomes more common with age as tear production naturally decreases.

Hormonal Changes

Hormonal shifts, particularly in women, can affect tear production and lead to dryness.How an Eye Exam Can Help

If your eyes are frequently watering or feeling irritated, it’s important to have your symptoms evaluated by an optometrist.

At our Forest Hill optometry clinic in Toronto, we can assess:

  • The quality and quantity of your tear film

  • Signs of inflammation on the eye surface

  • Meibomian gland function (oil glands along the eyelids)

  • Environmental or lifestyle factors contributing to dry eye

Dry eye is often multifactorial, meaning several factors may be contributing to your symptoms.

Treatment Options for Dry Eye

The good news is that dry eye is very treatable once the underlying cause is identified.

Depending on your symptoms, treatment may include:

Artificial Tears

Lubricating eye drops can help supplement your natural tear film and provide temporary relief.

Warm Compresses

Warm compresses can help open the oil glands in your eyelids, improving tear stability.

Eyelid Hygiene

Cleaning the eyelids can help reduce inflammation and improve tear quality.

Lifestyle Adjustments

Simple changes like taking screen breaks, using a humidifier, or adjusting lighting can make a noticeable difference.

Advanced Dry Eye Treatments

In some cases, your optometrist may recommend prescription treatments or specialized therapies depending on the severity of your symptoms.

When Should You See an Optometrist?

If you experience persistent watery eyes, irritation, or blurry vision, it’s worth scheduling an eye exam. Many people live with dry eye symptoms for years without realizing treatment is available.

Early treatment can help prevent symptoms from worsening and protect the health of your eyes.
