Burning usually comes from the surface of the eye or eyelids. These are common causes to read about next.

Dry eye A poor tear film leaves the surface irritated, gritty and burning. Eye allergies Itchy, watery, burning eyes triggered by pollen, dust or pets. Blepharitis Inflamed, crusty eyelid margins that irritate the eye surface. Conjunctivitis Red, burning eyes with watering or discharge. Contact lens discomfort Burning from overwear, poor hygiene or an ill-fitting lens. Ocular rosacea Burning, gritty eyes linked with facial rosacea and blepharitis.

What can help

Frequently asked questions

What causes burning eyes?

Dry eye, allergies, blepharitis and conjunctivitis are common causes. Burning with a painful red eye or vision changes needs prompt assessment.

Are burning eyes a sign of infection?

Not always. Many cases are dry eye or allergy. Infection is more likely if the eye is very red, painful, sticky or light-sensitive.

Can screen time cause burning eyes?

Screens do not usually damage the eyes permanently, but reduced blinking during long screen use can worsen dry eye and burning. Regular breaks and lubricating drops often help.
