Burning Eyes – Causes of Burning Eyes
Burning eyes affects about 30% of reading glasses wearers at one time or another. It is the commonest symptom of dry eyes. Most just suffer in silence, but there are simple steps that can be taken to help the condition.
Eye burning with discharge is burning, itching, or drainage from the eye of any substance other than tears. Lots of different things can make your eyes burn. Smoke, pollen, or a viral infection such as a cold or the flu can cause eyes to itch, burn, water, and redden. In these cases the burning and itching usually go away when the irritant is removed.
Sometimes burning and itching eyes are due to environmental pollutants that might be eliminated by social action. If secondhand cigarette smoke is annoying, say so. If an industrial plant in the area is polluting, contact the EPA for solutions. Unprotected eyes can also be burned by the ultraviolet (UV) rays from the sun, tanning lamps or arc welding equipment. Like sunburns to the skin, you won't feel pain until hours later, when the eyes and the area around them swell. Near-UV rays can damage your retina. The risk of sunburn to the eyes is very high when sunlight is reflected off water, sand or snow.
Causes of Burning eyes
Chronic dry or burning eyes can be caused by age, some medications, and disease. Itchy, burning eyelids can also result from infection.
Tears bathe the eye, washing out dust and debris and keeping the eye moist. They also contain enzymes that neutralize the microorganisms that colonize the eye. Tears are essential for good eye health. Allergy is caused by an oversensitive immune system, which leads to a misdirected immune response. The immune system normally protects the body against harmful substances, such as bacteria and viruses. It reacts to substances (allergens) that are generally harmless and in most people do not cause a problem. Sometimes burning and itching eyes are due to environmental pollutants that might be eliminated by social action. If secondhand cigarette smoke is annoying, say so. If an industrial plant in the area is polluting, contact the EPA for solutions. Pink eye or viral conjunctivitis causes a red or bloodshot eye and excessive tearing. If you suspect pink eye, remember to wash your hands often, and avoid touching the unaffected eye. The infection will run its course in about 10 days. During the normal aging process, our bodies and our eyes produce gradually less and less oil. This reduction in oil in the tear film results in quicker evaporation leading to the formation of dry spots on our eyes. |
