Eye symptoms due to an allergy are very common. Health care professionals refer to these eye conditions as allergic conjunctivitis. Allergic conjunctivitis means an inflammation of the conjunctiva and/or mucous membrane of the eyes as a result of contact with an allergen. Many people suffer the symptoms of allergic conjunctivitis, either seasonally (seasonal allergic conjunctivitis) or all year round (perennial allergic conjunctivitis).
An allergic reaction to the eyes is common in a grass and/or tree pollen allergy, a house dust mite allergy and a pet allergy . In case of a contact allergy and a food allergy eye symptoms are less common. Eye symptoms due to an allergic reaction can occur in one eye or both eyes.
Below a number of symptoms are stated which can be caused by an allergic reaction. These symptoms are all related to the eyes:
- Burning sensation
- Red eyes
- Excess lacrimation
- Swollen eyelids
- Light hypersensitivity
Sometimes an inflammation of the eyes can also be the result of an allergy to, for example, eye drops. In that case it is classified as a drug allergy.
Eye symptoms in allergy are common in combination with respiratory conditions, also referred to as allergic rhinitis and allergic asthma.
