Burning eyes can be caused by environmental or allergenic irritants and medical conditions such as conjunctivitis and dry eye syndrome, states EyeHealthWeb.com. Burning eyes can also be caused by certain medications, contact lenses, age-related factors and bright lights.
Unless burning eyes are a symptom of a medical condition, they are treated by removing the irritant causing the problem, notes EyeHealthWeb.com. Common environmental irritants include dust, sun exposure, smoke, airborne chemicals, hair spray and smog. Allergenic irritants, such as pollen, dust, mold and pet dander, can also cause a person's eyes to burn.
Conjunctivitis, also known as pink eye, is an infection or inflammation of the conjunctiva area of the eye, explains Mayo Clinic. It has bacterial, viral and allergenic causes, all which require different treatment methods. Get treatment as soon as possible because some types of conjunctivitis are contagious.
Dry eye syndrome occurs when the eyes are unable to maintain a normal coating of tears, according to MedlinePlus. This condition can have a variety of causes including age-related and hormonal factors; dry environment; sun exposure; and eye surgery. In addition to burning eyes, the condition can cause symptoms such as blurred vision and sensitivity to light. Dry eye syndrome is usually treated with regular use of artificial tears.
