Can your eyeball swell from allergies?

When your eyes are exposed to allergy-causing substances, a substance called histamine is released by your body. The blood vessels in the conjunctiva become swollen. The eyes can become red, itchy, and teary very quickly. The pollens that cause symptoms vary from person to person and from area to area.

What allergies can cause eye swelling?

Common allergens that can trigger swollen eyes include pollen, dust and pet dander, and can sometimes be due to the changing of the seasons. Some types of contact solution and eye drops may also trigger an allergic reaction in certain individuals with sensitive eyes.

What causes eyes to swell?

The most common cause of eyelid swelling is allergies, either by direct contact with the allergen (such as animal dander entering your eye) or from a systemic allergic reaction (such as a food allergy or hay fever). If one eyelid is swollen, a common cause is a chalazion, an obstructed gland along the rim of an eyelid.

How long can allergic reaction last?

You usually don't get a reaction right away. It can take anywhere from a few hours to 10 days. Typically, it takes from 12 hours to 3 days. Even with treatment, symptoms can last 2 to 4 weeks.

What happens in body during allergic reaction?

It starts when you come into contact with a trigger that you inhale, swallow, or get on your skin. In response, your body starts to make a protein called IgE, which grabs onto the allergen. Then histamine and other chemicals get released into the blood.
