Why Do My Eyes Burn?
The honest verdict
This is frequently allergy-related
Yes — burning eyes are often caused by allergies. Allergic conjunctivitis is one of the most common causes, especially when the burning is paired with itching, redness, and watery eyes. Seasonal allergens (pollen, grass, ragweed) and indoor allergens (dust mites, pet dander, mold) can trigger this reaction. However, burning eyes can also come from dry eye syndrome, eye strain, or irritants like smoke and chlorine — so the full pattern of symptoms helps determine the cause.
This is a general research summary, not a diagnosis. It can't tell you what's causing your symptom — a clinician can.

When burning eyes is an emergency
Most of the time this can be handled calmly. But a few signs mean you shouldn't wait. Match what you're seeing to the right level of care below.
If any emergency sign below is present, call 911 or go to the ER now.
- Emergency
Sudden burning with vision loss, blurred vision, or seeing halos around lights — go to the ER (possible acute glaucoma or corneal ulcer).
Call 911 or go to the ER now
- Emergency
Burning after a chemical splash or foreign object injury — flush the eye with clean water for 15 minutes and go to the ER.
Call 911 or go to the ER now
- Urgent
Burning with severe eye pain, light sensitivity (photophobia), or the feeling of something stuck in the eye — seek urgent care or ER (possible corneal abrasion, ulcer, or infection).
Get seen today — urgent care or same-day visit
- See a doctor
Burning accompanied by thick, green or yellow discharge with eyelid swelling — see a clinician promptly (possible bacterial conjunctivitis needing antibiotics).
Book a routine visit with a clinician
- See a doctor
Burning that persists for more than a few days despite artificial tears and avoiding irritants — see an eye doctor (possible chronic dry eye, blepharitis, or other condition needing treatment).

When in doubt, err toward getting seen. These tiers are a general guide, not a substitute for a clinician's judgment about your specific situation.
Key facts
Allergic conjunctivitis affects up to 40% of the population in the United States, making it one of the most common causes of burning and itchy eyes.
Dry eye syndrome affects an estimated 5-30% of adults worldwide, with higher rates in women and older adults.
The average person blinks about 15-20 times per minute, but that rate drops by half or more during screen use, contributing to dry and burning eyes.
What's causing it
The same symptom can come from very different places. Here are the usual suspects for Eyes — the surface of the eye (cornea and conjunctiva) and the surrounding eyelids and tear film, tagged by mechanism and how common each one is — so you can see where an allergy actually fits.
Allergic conjunctivitis (eye allergy)
When allergens like pollen, dust mites, pet dander, or mold come into contact with the eyes, the immune system releases histamine, causing burning, itching, redness, and watery discharge. Seasonal allergies (hay fever) are a common trigger. Over-the-counter antihistamine eye drops and avoiding allergens can help.
Dry eye syndrome (keratoconjunctivitis sicca)
Insufficient or poor-quality tears cause the eyes to feel dry, gritty, and burning — often worsening with screen use, reading, or in dry or windy environments. It is more common with age, contact lens wear, and certain medications (antihistamines, decongestants). Artificial tears and breaks from screens can provide relief.
Environmental irritants
Smoke, smog, chlorine in swimming pools, strong fumes (cleaning products, paint), or even dry indoor air can irritate the eyes and cause a temporary burning sensation. Rinsing the eyes with clean water or artificial tears usually resolves the irritation.
Eye strain (asthenopia)
Prolonged screen time, reading in dim light, or driving long distances can tire the eye muscles and lead to burning, fatigue, and discomfort. The 20-20-20 rule — looking at something 20 feet away for 20 seconds every 20 minutes — can help reduce strain.
Contact lens overwear or poor hygiene
Wearing contact lenses too long, sleeping in them, or not cleaning them properly can cause corneal irritation, dryness, and a burning sensation. This can also increase the risk of infection. Removing lenses and giving the eyes a break is the first step.
Conjunctivitis (pink eye) — infectious
Viral or bacterial conjunctivitis can cause burning, redness, discharge, and crusting. Viral conjunctivitis typically causes watery discharge and may accompany a cold; bacterial conjunctivitis often produces thick, yellow or green discharge. Both are contagious and may need medical treatment.
Where allergy actually fits in
When a symptom like this is allergy-driven, it usually points to a specific trigger. Knowing which one is the difference between guessing and actually fixing it.
Burning eyes are often caused by allergies. Allergic conjunctivitis occurs when the immune system overreacts to an allergen — pollen, dust mites, pet dander, or mold — releasing histamine that causes burning, itching, redness, and watery eyes. This is especially common during spring and fall allergy seasons. Over-the-counter antihistamine eye drops (like ketotifen) and oral antihistamines can help. If eye allergies are frequent, an allergist can identify the specific triggers through allergy testing and recommend treatments such as allergy drops or immunotherapy to reduce sensitivity.
Relief you can try at home
If your symptom is mild and you have no red-flag signs, these gentle steps often help. They soothe — they don't replace figuring out the cause.
- 1
Use artificial tears
Over-the-counter preservative-free artificial tears can lubricate the eyes and relieve burning from dryness or mild irritation. Use as often as needed, but avoid drops that claim to 'get the red out' — they can worsen dryness with frequent use.
- 2
Apply a cold compress
A clean, cool, damp cloth placed over closed eyes for 5-10 minutes can soothe burning and itching from allergies. This helps reduce inflammation and provides immediate comfort.
- 3
Avoid allergens and irritants
If allergies are the likely cause, avoid spending time outdoors during high pollen counts, keep windows closed, use an air purifier, and wash your face and hands after being outside. Avoid smoke, strong fumes, and chlorinated pools.
- 4
Follow the 20-20-20 rule for screen use
To reduce eye strain from screens, every 20 minutes look at something 20 feet away for at least 20 seconds. Blink fully and often to keep the eyes moist. Consider using blue-light filtering glasses if screen time is prolonged.
- 5
Remove contact lenses and rest your eyes
If you wear contact lenses, remove them at the first sign of burning and switch to glasses until symptoms resolve. Clean and disinfect lenses thoroughly before reusing, and avoid sleeping in lenses.
Stop any step that makes things worse. If the symptom isn't easing within a few days, check in with a clinician.
When to see a doctor
See a doctor if burning eyes are accompanied by vision changes (blurred vision, halos, vision loss), severe eye pain, light sensitivity, or thick yellow or green discharge. Also seek care if burning persists for more than a few days despite home care, or if you have a known eye condition like glaucoma or recurrent corneal erosions. If a chemical splash or foreign object caused the burning, flush the eye and go to the ER immediately.
❓Frequently Asked Questions
It is uncommon for eye allergies to cause burning without any itching. Allergic conjunctivitis typically produces both burning and itching, along with redness and watery discharge. If eyes burn but do not itch, dry eye syndrome or an environmental irritant (smoke, chlorine, fumes) is a more likely cause. A clinician can help distinguish between the two.
Allergic conjunctivitis is caused by an immune reaction to an allergen and typically includes itching, redness, and watery discharge alongside burning. Dry eye syndrome results from insufficient tears or poor tear quality and causes a gritty, sandy, or burning sensation without significant itching. Dry eye often worsens with screen use, reading, or in dry environments, while allergies flare with allergen exposure.
Yes — preservative-free artificial tears are safe for general dryness and mild irritation. For allergy-related burning, antihistamine eye drops (such as ketotifen) can be effective. Avoid drops that claim to 'get the red out' (vasoconstrictors) for more than a few days, as they can cause rebound redness and worsen dryness with prolonged use.
See an eye doctor if burning persists for more than a few days despite home care, if you have vision changes, if there is thick discharge, or if you experience eye pain or light sensitivity. People who wear contact lenses should see an eye doctor at the first sign of persistent burning to rule out corneal irritation or infection.
Yes — prolonged screen use reduces blink rate, which leads to tear evaporation and dry eyes. This can cause a burning, tired, or gritty sensation. The 20-20-20 rule (look at something 20 feet away for 20 seconds every 20 minutes) and using artificial tears can help. Adjusting screen brightness and reducing glare also reduces strain.
Burning eyes are not a classic or common symptom of COVID-19. The most common symptoms are fever, cough, shortness of breath, fatigue, and loss of taste or smell. While some people with COVID-19 have reported conjunctivitis (pink eye), burning eyes alone are far more likely to be caused by allergies, dry eye, or an irritant.
