Burning sensation in the eye can be caused by allergy, dryness, tiredness, vision stress (like computer work) or a combination of the aforementioned factors.
The possible causes for burning sensation in the eye include:
Wearing your contact lenses for prolonged periods
Exposure to environmental pollutants such as tobacco smoke, or dust
Extremes of cold or hot dry air
Chemicals found in household cleaning solvents such as bleach, soap and shampoo
Chlorine in swimming pools
The treatment for burning eyes varies depending on the cause. In many cases, the burning sensation goes away by itself when you get away from the irritating factor, such as smoke. In other cases, use of over-the-counter artificial tears or antihistamines can relieve burning eyes. If you have conjunctivitis caused by bacteria, your eye doctor may prescribe antibiotic eye drops or ointment.
