Itchy or burning eyes are one of the most common symptoms seen in ophthalmology consultations. Although in many cases it is related to environmental factors or allergies, it can also be a sign of eye diseases that require specific treatment.
At Clínica Nivaria , we have a team of ophthalmologists specializing in ocular surface diseases, prepared to identify the cause of discomfort and apply the most appropriate treatment in each case. Below, we explain everything you need to know about this symptom: from its most common causes to how to prevent it.
What does it mean to have itchy or burning eyes?
Itching is described as a constant urge to scratch the eyes , while stinging is a burning or stinging sensation on the surface of the eye. Both symptoms often appear together and can affect one or both eyes, occasionally or persistently.
They are often accompanied by other signs, such as:
- Eye redness
- Tearing
- Sensation of a foreign body
- Inflammation of the eyelids
- Photophobia (sensitivity to light)
- Eye secretion
- Blurred vision
Identifying the source of these problems is essential to resolving them effectively.
Most frequent causes of itchy or burning eyes
1. Eye allergies
Allergic conjunctivitis is the most common cause of itchy eyes. It occurs when the eye comes into contact with allergens such as:
- Pollen (seasonal allergy)
- Dust mites
- Animal dander
- Mold
- Cosmetics or chemical products
It is characterized by:
- Intense itching
- Tearing
- Redness
- Inflammation of the eyelids
- Affects both eyes
It is more common in patients with a history of asthma, rhinitis, or atopic dermatitis.
2. Dry eye syndrome
When the surface of the eye is not properly lubricated, constant friction occurs, causing stinging, irritation, and a gritty sensation . Although it may seem contradictory, many people with dry eye also experience reflex tearing .
It is more common in:
- Older people
- Postmenopausal women
- Screen users
- People who wear contact lenses
- Rooms with air conditioning or heating
3. Blepharitis
Chronic inflammation of the eyelid margins. It is often associated with Meibomian gland dysfunction. It causes:
- Itching and burning in the eyes
- Dried secretions on the eyelashes
- Sensation of a foreign body
- Eye strain
It is a common cause of persistent discomfort.
4. Irritative or infectious conjunctivitis
Viral or bacterial infections can cause mild itching, although stinging or burning is more common. In these cases, it is accompanied by:
- Redness
- Secretion (watery or purulent)
- Discomfort when blinking
- Sensitivity to light
Chemical or irritant conjunctivitis (caused by smoke, chlorine, cosmetics, or pollution) can also produce these symptoms.
5. Prolonged use of screens
The continuous use of computers, mobile phones or tablets causes a reduction in blinking, which promotes dry eye and eye irritation .
6. Contact lenses
Prolonged or incorrect use of contact lenses can cause:
- Dryness
- Stinging
- Sensation of a foreign body
- Increased susceptibility to infections
7. Environmental factors
Wind, smoke, dust, pollution, or excessive air conditioning can irritate the surface of the eye, especially in people with sensitive eyes.
When is it necessary to see an ophthalmologist?
Although itching or burning may seem like mild symptoms, it is important to consult a specialist if:
- They persist for more than 2-3 days
- They are accompanied by eye pain, thick discharge, or decreased vision.
- They affect quality of life or work performance
- Do you have a history of allergies, dry eye, or autoimmune diseases?
- You wear contact lenses and notice persistent discomfort.
- Self -treatment doesn't work or the symptoms get worse
At Clínica Nivaria , we perform a precise evaluation to identify the cause and apply the most appropriate treatment.
