Burning eyes are usually a reaction to irritation or to not having enough tears to keep the eye surface lubricated [1]. Dry eye and allergies are the most common causes. Blepharitis, dry indoor air, pink eye, ocular rosacea and irritants such as chlorine, smoke, cosmetics and cleaning products are other frequent causes [1]. Most burning settles with lubricating drops, a compress and avoiding the trigger. Burning that does not improve within a day or two, or that comes with pain, light sensitivity or vision loss, needs an eye exam [1].
If a chemical gets in your eye, flush it with water or another drinkable liquid for at least 15 minutes, keeping the eye open, then get emergency care [2]. If you wear contact lenses and your eye burns with pain, redness, light sensitivity or blurred vision, take the lenses out and call your eye doctor right away [3].
Key takeaways
In this article

|---|---|---|
| Gritty, tired eyes, worse with screens, wind or dry heated air | Dry eye or low humidity [1,5] | Preservative-free artificial tears and regular screen breaks [1,5] |
| Itching and watering, around pollen, dust or pets | Allergies [1] | Antihistamine tablets or drops; avoiding triggers [1] |
| Red, swollen, crusty eyelid edges | Blepharitis [1] | Compresses and gentle daily eyelid cleaning [1] |
| Redness of the eyes and the skin around them, crusty discharge | Ocular rosacea [1] | An eye exam to confirm it and plan treatment |
| Red eye with discharge | Pink eye (conjunctivitis) from allergy, a virus or bacteria [1] | Depends on the cause; see a doctor if it is not settling |
| After swimming, smoke, makeup or cleaning products | Irritants [1] | Rinsing with clean water or a saline eye wash [1] |

Burning is a sign that the front surface of the eye is irritated or not well lubricated. It can come on suddenly and pass quickly, or it can last for weeks or months [1]. In dry eye, the eyes either do not make enough tears or the tears evaporate too quickly [1]. Screens, medicines and the environment often play a part; our guide to what causes dry eyes all of a sudden explains these triggers.
Less common causes include Sjögren's syndrome, which reduces the body's moisture production including tears, and pterygium, a growth of tissue on the eye surface that can start with burning, dryness and grittiness [1]. Read more about Sjögren's and autoimmune dry eye.
When the eyelids are the source, burning often comes with crusting at the lashes and red, swollen lid edges, which is typical of blepharitis [1]. Our guides to blepharitis treatment and ocular rosacea cover these in detail.
Eyes that burn and water at the same time are common. When the eye surface is irritated, the body makes reflex tears to flush it. These tears carry more salt than everyday tears, which is one reason they can sting [4]. Dry eye can also make the eyes water, which is explained in what dry eyes feel like and why they water. Burning with itching and watering is more typical of allergies [1].
If your eyes burn most when you wake up, our guide to waking up with dry eyes covers the usual causes.
Burning in just one eye is more likely to have a local cause. A speck or eyelash in the eye can burn and water; do not rub it, let your tears or an eye wash rinse it out, and see an eye doctor promptly if it does not come out [2]. In a contact lens wearer, a burning, painful red eye can be the start of a corneal infection [3]. A shingles rash on one side of the forehead or around one eye can cause burning, throbbing or itching around that eye [6].
Burning or aching that continues when the eye looks healthy can come from oversensitive corneal nerves, a condition called corneal neuralgia.
If the cause is everyday dryness, allergy or irritation rather than an infection or injury, these steps often help [1]:
To prevent burning, avoid rubbing your eyes, use fragrance-free products, wear goggles when swimming, wear sunglasses with 100% UV protection outdoors and safety glasses around tools, and do not share eye drops, makeup or towels [1].

When burning keeps coming back because of chronic dry eye, blepharitis or ocular rosacea, Netra Eye Institute offers integrative dry eye care alongside the treatment from your eye doctor. It does not replace an eye examination, and a painful red eye, vision change or chemical injury needs medical care first. Learn about dry eye care at Netra.
Most often because the eye surface is dry or irritated. Dry eye and allergies are the most common causes, followed by blepharitis, irritants, dry air and pink eye [1].
Tears contain salt. When your eyes are already dry or irritated, or your tears are saltier than usual, crying can make them sting [4].
Yes. Long screen use is linked to eye strain and dry eyes, which can feel like burning. Regular breaks and an up-to-date glasses prescription help [5].
Rinse out any irritant with clean water or saline, use lubricating drops and place a cool compress over closed eyes for 5 to 10 minutes [1]. For a chemical, flush for at least 15 minutes and get emergency care [2].
Usually not. They are more serious with pain, light sensitivity, vision loss, fever or a rash, after a chemical splash, or in a contact lens wearer with a painful red eye [1,2,3].
Yes. Pollen, dust, mold and pet dander are common triggers, and itching often comes with the burning [1].
