Itchy eyes or ocular allergy, is the result of an allergy or a condition known as dry eye syndrome. Itchy eyes related problems can be triggered by exposure to pollen, animal fur, mould, dust mites, make-up, or eye drops. The body reacts to the trigger by releasing histamine, causing the blood vessels in the eye/or around the eyes to dilate and irritating the nerve endings so the eyes water. When the eyes turn red because of an allergy, it is known as allergic conjunctivitis. Other types of allergy may also lead to itchy eyes.
Dry eye syndrome-
Infection due to contact lenses
Irritation due to exposure of eyes to chemicals like cigarette smoke and gases
Inflammation of the eyelids
When you’re dealing with a mild case of allergic itching, you can use a cold cloth or a cold compress over the eyes to ease the discomfort of itching. You can also try splashing your eyes with cold water. If your eye itching is due to some particles or dust in your eyes, you can remove it from your eyes by using warm water or saline solution.
Closing the windows of your car or house. Wearing sunglasses when venturing outside to avoid contact with allergens. Avoid rubbing your eyes. As constant rubbing of the eyes can damage the top layer of the eye, which can lead to pain and infection.
