Allergic conjunctivitis (CA) is a self-limiting bilateral conjunctival inflammatory process. AC occurs in sensitized patients without gender difference.

The most common target organ for mast cell IgE hypersensitivity reaction may be the eye. 
The allergic reaction in allergic conjunctivitis is caused by the direct exposure of the surfaces of the ocular mucosa to environmental allergens, such as tree pollen, herbs and weeds. These allergens interact with the specific pollen IgE present in mast cells in the eyes

Conjunctivitis is a common eye disease because the conjunctivae are continuously exposed to microorganisms and environmental agents that can cause infections or allergic reactions. Conjunctivitis can be acute or chronic, depending on the duration of the condition, the severity of the symptoms and the type of organism or agent involved. It can affect one or both eyes. If caused by an infection, it can easily be passed on to others during close physical contact, particularly among children in a daytime environment. Other names for conjunctivitis include pinkeye and red eyes

Allergic conjunctivitis can be treated very well with over-the-counter antihistamines which can help prevent mast cell production of histamine inside the eyes. 
Allergic conjunctivitis is an illustration of soluble antigens that bind to IgE and cause mast cell degranulation, type I hypersensitivity. This type of conjunctivitis differs with acute or chronic colds that are part of another syndrome such as hay fever or dermatitis. of eyelid contact
