Why Do My Eyes Burn? Causes & Relief

Burning eyes can happen after hours on a screen, while wearing contact lenses or even when your eyes are watering.

Common causes include dry eye, allergies, eyelid inflammation and environmental irritation. The right treatment depends on what’s causing the discomfort.

If burning keeps returning, an eye examination at Oshawa Eye Care can help identify the cause and guide your treatment.

Seek urgent eye care if burning comes with significant pain, sudden vision changes or severe light sensitivity. If a chemical splashes into your eye, immediately rinse with clean, lukewarm running water for at least 20 minutes and seek emergency medical care.

Common Causes of Burning Eyes

1. Dry Eye and Meibomian Gland Dysfunction

Dry eye occurs when your eyes don’t produce enough tears or your tears don’t keep the eye surface properly lubricated.

Along with burning or stinging, you may notice:

A gritty or sandy feeling
Redness
Watery eyes
Fluctuating blurry vision
Eye fatigue
Contact lens discomfort

A common contributor is meibomian gland dysfunction (MGD). These tiny glands along your eyelids produce oil that helps prevent tears from evaporating too quickly. When the glands become blocked or don’t work properly, your eyes can feel dry and irritated.

Dry eyes can also water excessively. Irritation triggers reflex tears, but these tears may not provide lasting relief.

2. Screen Use

When concentrating on a computer or phone, you may blink less often or incompletely. This allows the tear film to break down more quickly, leaving your eyes feeling dry, tired or burning.

If symptoms regularly return during screen use, underlying dry eye may also be contributing.

3. Allergies

Pollen, dust and pet dander can cause burning, redness and watering. Itching is a particularly useful clue, especially if you also have sneezing or a runny nose.

Allergies and dry eye can occur together, so symptoms alone may not reveal the full picture.

4. Eyelid Inflammation

Blepharitis, or inflammation around the eyelids, can cause burning, irritated eyelids and crusting around the eyelashes.

It can also affect the meibomian glands and contribute to dry eye. An eye examination can help determine whether eyelid inflammation is part of the problem.

5. Contact Lenses

Burning with contact lenses may be related to dryness, prolonged wear, lens fit, deposits or sensitivity to lens-care products. Infection is another possible cause.

Remove your contacts if your eyes become irritated. If you have pain, significant redness, discharge or a change in vision, seek urgent eye care and leave your lenses out until you’ve been assessed.

6. Environmental Irritation

Smoke, wind, dust, fragrances, chlorinated water and dry indoor air can irritate your eyes.

Occasional burning may settle after you leave the environment. Frequent or lingering symptoms deserve an examination, particularly if your eyes are becoming increasingly sensitive.

What Can Help Burning Eyes?

For mild irritation without pain or vision changes, these steps may help:

Take regular screen breaks and make a conscious effort to blink fully.
Avoid smoke, direct airflow and other triggers that worsen your symptoms.
Consider lubricating eye drops. Your optometrist can recommend an appropriate option, including preservative-free drops when needed.
Take a break from contact lenses if they cause discomfort.

Warm compresses and eyelid care may help some people with MGD or blepharitis, but the best approach depends on the diagnosis.

If symptoms keep returning, don’t rely on temporary relief alone.

Burning Eyes and Dry-Eye Assessment in Oshawa

At Oshawa Eye Care, our optometrists can assess your tear film, eyelids and eye surface to determine what’s contributing to persistent burning.

Depending on the findings, your treatment plan may include:

Lubricating eye drops (Preservative free)
Warm compresses and eyelid care
Allergy management
Changes to contact lenses or lens-care products
Prescription treatment
Targeted treatment for meibomian gland dysfunction

For selected patients with evaporative dry eye and MGD, IPL (Intense Pulsed Light) may be considered as part of a personalized treatment plan. It isn’t the right option for every cause of burning eyes.

When Should You See an Eye Doctor?

Book an eye examination if:

Your eyes burn frequently or symptoms keep returning
Eye drops provide little or only temporary relief
You have ongoing redness or fluctuating blurry vision
Contact lenses regularly feel uncomfortable
Symptoms interfere with reading, screen use or daily activities

Seek urgent care for significant pain, sudden vision changes, severe light sensitivity, marked redness, an eye injury or a painful red eye while wearing contacts.

Sudden or severe symptoms should not automatically be assumed to be dry eye.

Frequently Asked Questions

Why do my eyes burn even though they’re watering?

Dry eye can trigger reflex tearing when the eye surface becomes irritated. Allergies can also cause burning and watering. An examination can help distinguish between them.

Can screen time make my eyes burn?

Yes. Reduced or incomplete blinking during screen use can contribute to dryness, burning and fluctuating blurry vision.

Why do my eyes burn every day?

Daily burning may be associated with dry eye, MGD, allergies, eyelid inflammation or repeated exposure to irritants. Persistent symptoms should be assessed rather than assumed to have one cause.

Can dry eye cause blurry vision?

An unstable tear film can cause vision to fluctuate, sometimes clearing briefly after blinking. Persistent blurriness or sudden vision changes need assessment.
