Understanding Eye Burning: Common Causes and Symptoms

Eye burning is a frequent complaint that affects millions of people each year. According to the American Academy of Ophthalmology, dry eye syndrome alone impacts approximately 16 million Americans, with many experiencing a burning sensation as a primary symptom. Eye burning can range from mild irritation that resolves quickly to chronic discomfort that interferes with daily activities like reading, working, or driving.

The sensation of burning eyes occurs when the outer surface of your eye, called the cornea, becomes irritated or inflamed. This can happen for various reasons, from temporary environmental factors to underlying medical conditions. Understanding what causes your specific burning sensation is the first step toward finding relief.

Common symptoms accompanying eye burning include redness, watering eyes, grittiness or foreign body sensation, sensitivity to light, and blurred vision. Some people describe the feeling as sand in the eye, while others report a stinging or scratchy sensation. The burning may affect one eye or both, and it may be constant or intermittent throughout the day.

Several factors influence how noticeable eye burning becomes. The time of day matters—many people experience worse symptoms in the evening. Environmental conditions like low humidity or wind can trigger or worsen burning. Additionally, activities requiring sustained focus, such as computer work or reading, can intensify the sensation because people blink less frequently when concentrating.

Practical Takeaway: Keep a simple log of when your eye burning occurs, what you were doing beforehand, and what the weather or indoor conditions were like. This information helps identify patterns and potential triggers, which is valuable if you decide to see an eye care professional.

Dry Eye Syndrome: The Leading Cause of Eye Burning

Dry eye syndrome is the most common cause of eye burning and affects a growing portion of the population. Research from the journal Ocular Surface indicates that dry eye prevalence ranges from 5% to 50% globally, depending on the population studied and diagnostic criteria used. In the United States, it is estimated that up to 16 million adults have dry eye disease, with women and people over age 50 experiencing it more frequently.

Your eyes remain healthy through a delicate balance of tear production and tear composition. Tears contain water, oils, and mucus in precise proportions. When this balance is disrupted—either through reduced tear production or increased tear evaporation—dry eye syndrome develops. The condition causes the corneal surface to dry out, leading to burning, irritation, and sometimes temporary vision changes.

Two primary types of dry eye exist. Aqueous-deficient dry eye occurs when tear glands produce insufficient tears. Evaporative dry eye happens when tears evaporate too quickly, usually due to problems with the oil layer of tears. Many people experience a combination of both types. Risk factors include age, hormonal changes, certain medications (antihistamines, decongestants, and some blood pressure medications increase dry eye risk), autoimmune conditions like Sjögren's syndrome, and extended screen time.

Modern work environments significantly contribute to dry eye development. The American Optometric Association reports that people blink approximately 66% less when looking at digital screens compared to normal conversation. Reduced blinking means less tear distribution across the eye surface. Someone working eight hours daily at a computer may experience substantial tear film disruption by day's end.

Practical Takeaway: If you spend extended periods on screens, implement the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. This simple practice prompts more frequent blinking and allows tear film to redistribute, potentially reducing dry eye symptoms significantly.

Environmental and Lifestyle Factors Contributing to Eye Burning

Your surrounding environment plays a substantial role in eye comfort. Low humidity is a primary culprit—heating systems in winter, air conditioning in summer, and airplane cabins all create extremely dry air that accelerates tear evaporation. Relative humidity below 30% is considered problematic for eye health. Many office buildings maintain humidity levels between 20-30%, and airplane cabins can drop to 10-15% humidity during flight.

Air quality directly impacts eye burning sensations. Smoke from tobacco, cannabis, or fires irritates the ocular surface and triggers inflammation. Pollution, including ground-level ozone and particulate matter, causes similar irritation. People living in areas with poor air quality or those exposed to occupational dust, chemicals, or fumes experience higher rates of eye burning.

Allergens provoke eye burning in millions of people seasonally and year-round. Pollen affects approximately 50 million Americans annually, according to the American College of Allergy, Asthma and Immunology. Pet dander, dust mites, and mold spores trigger eye irritation in sensitive individuals. During allergy season, some people experience persistent eye burning that worsens outdoors or in dusty environments.

Lifestyle habits significantly influence eye comfort. Inadequate sleep reduces tear production and impairs the eye's natural healing processes. Alcohol and caffeine consumption can have dehydrating effects that impact tear quality. Smoking constricts blood vessels and damages tear gland function—smokers have substantially higher dry eye rates than non-smokers. Poor nutrition, particularly deficiencies in omega-3 fatty acids and vitamins A, D, and E, may compromise tear production and corneal health.

Contact lens wear is a common lifestyle factor associated with eye burning. Approximately 41 million Americans wear contact lenses. Lenses can reduce oxygen reaching the cornea, alter tear film stability, and cause dehydration if worn beyond recommended durations. Improper lens care, wearing daily disposable lenses longer than recommended, or sleeping in non-overnight lenses increases burning risk substantially.

Practical Takeaway: Identify which environmental or lifestyle factors coincide with your eye burning. If dry indoor air worsens symptoms, using a humidifier to maintain 40-50% humidity may help. If allergens trigger symptoms, keeping windows closed during high pollen days and removing clothing when entering your home reduces exposure. If screen time is a factor, reducing daily usage or taking frequent breaks provides measurable relief for many people.

Medical Conditions and Medications Associated with Eye Burning

Several medical conditions cause or contribute to eye burning. Blepharitis, inflammation of the eyelid margins, affects 37-47% of people who visit eye clinics, according to various studies. This condition disrupts the oil glands in eyelids, affecting tear film stability and causing persistent burning and grittiness.

Meibomian gland dysfunction (MGD) is increasingly recognized as a significant cause of dry eye and burning. These glands, located in the eyelids, produce the oil layer that prevents tear evaporation. When these glands malfunction, typically due to inflammation or clogging, tears evaporate too quickly and eye burning results. MGD is present in approximately 70% of dry eye patients.

Autoimmune conditions frequently cause eye burning. Sjögren's syndrome specifically attacks tear and salivary glands, resulting in severe dry eye. Rheumatoid arthritis, lupus, and scleroderma can also produce ocular surface disease. Women are diagnosed with Sjögren's syndrome nine times more frequently than men, and diagnosis typically occurs after age 40.

Hormonal changes significantly affect tear production and composition. Pregnancy, menopause, and hormonal contraceptive use alter hormone levels that influence tear gland function. Approximately 60% of menopausal women experience dry eye symptoms, making this a critical time for eye care attention.

Numerous medications contribute to eye burning through reduced tear production or altered tear composition. Common culprits include antihistamines used for allergies, decongestants, blood pressure medications (beta-blockers and ACE inhibitors), antidepressants, isotretinoin for severe acne, and antiandrogen medications. If eye burning coincides with starting a new medication, discussing alternatives with your prescribing physician may be worthwhile.

Dermatological conditions affecting the eyelids, such as rosacea or eczema, cause inflammation that disrupts tear film and triggers burning. Chemical or thermal burns to the eye surface represent medical emergencies requiring immediate professional care, though they are less common causes of chronic burning.
