What is Eye Allergy?

An eye allergy is also called as a conjunctival allergy. Conjunctiva is the delicate membrane covering the inside of an eye and the eyelid. Eye allergy occurs when something to which the person is allergic, irritates this membrane in the eye.

Eye allergy occurs when the body recognizes certain substance as a harmful foreign body which is not actually harmful. Thus the body reacts against this substance and produces a reaction which gives rise to abnormal signs and symptoms like itching, redness or pain in the eyes.

Eye allergies can be caused by pollens, dust particles, mold spores or pet dander.

An eye allergy is not contagious and it doesn’t spread to others but can cause secondary infections which can cause harm to the eyesight.


Symptoms  of Eye Allergy

In most of the cases, both the eyes are affected together if the person has an eye allergy.

The symptoms can be:

  • Itching of the eyes
  • Watering eyes
  • Redness
  • Sensitivity to light
  • Swelling of the eyelids
  • Sensation of foreign bodies in the eyes
  • Burning of the eyes

The symptoms of an eye allergy may be associated with other symptoms like nasal discharge, sneezing, and stuffy nose.

There can be a secondary infection of the eyes if the patient continuously rubs his/her eyes due to itching and discomfort.


Causes of Eye Allergy

An eye allergy develops when a person’s body overreacts to a certain substance which is not actually harmful to him. This reaction causes the immune system of that person to release certain antibodies against this substance. This reaction leads to the release of certain chemicals like histamine. This release of chemicals gives rise to signs and symptoms.


Diagnosis of Eye Allergy

The person who is suffering from an eye allergy is asked about his/her medical history whether he/she had suffered from such symptoms before after an exposure to any particular substance. He will also be asked about the family history of any allergies if present.

Certain tests are needed to confirm the diagnosis of an eye allergy. These include:

  • Seeing the affected eye of the patient with a microscopic instrument which shows the swollen blood vessels.
  • Another test that can be carried out is scraping a little portion of the conjunctiva that is the inner membrane of the eyes to see the white blood cells which are present on the conjunctiva when the patient is suffering from an eye allergy.

Self help

  • Cleaning the house regularly to keep the amount of dust which can cause an eye allergy as less as possible.
  • Keep the pet animals out of the house or bedroom to avoid exposure to pet dander.
  • Avoid going outdoors when the pollen count is high in the air.
  • Wear sunglasses to protect the eyes from getting exposed to the pollens.
  • Application of saline eye drops after coming back home from outside to wash off the allergens that may have entered into the eyes.
  • To reduce the exposure to mold spores, the humidity in the house should be kept low and the kitchens, bathrooms, and basements should be kept clean.
  • The eyes should not be rubbed constantly. It can cause the symptoms to become more severe and can lead to infection.
