Allergic conjunctivitis is an adverse immune response. It occurs when an irritating substance or allergen comes into contact with your eyes.

Your immune system defends the body from pathogens, like bacteria and viruses. However, it does this to prevent illnesses.

People with allergies have an immune system that mistakes allergens as dangerous substances. This makes the immune system produce chemicals to fight the allergen. It does this even though the allergen might be harmless.

You may get an allergic reaction when you come in contact with seasonal allergens. You may also react to dust, dander from pets, and other indoor allergens. These may cause chronic or perennial conjunctivitis.

Perfume, makeup, or other chemicals can also trigger eye allergies called contact conjunctivitis. Contact lenses can also cause an allergic reaction called giant papillary conjunctivitis

The immune system reacts to these allergens by releasing histamine. This causes an allergic reaction‘s uncomfortable symptoms like red itchy watery eyes. It can also cause sneezing, runny nose, and coughing.
