The medical term for eye allergies, sometimes called pink eye, is allergic conjunctivitis. It is an irritation or inflammation of the part of the eye called the conjunctiva. The conjunctiva is a piece of tissue that lines the inside of the eyelid to protect the eye and keep it moist. Common allergy triggers or a bacterial or viral infection can cause this condition. If eye allergy symptoms appear, it is important to determine the cause so the right treatment approach can be formed and because bacterial and viral eye allergies are contagious.
Itchy Eyes
Common substances such as pollen, pet hair, mold, smoke, dirt and pollution cause most eye allergies, claims the Asthma and Allergy Foundation of America. These substances can get into and irritate the eyes, making them itchy. Eye allergies can be especially problematic for those who wear contact lenses, as irritants can build up on the lens. In these cases, single use contact lenses may be a better option.
Redness and Swelling
Allergens can irritate the eyes and make them red if substances in the air get into the eye or if the eyes are rubbed with the hands that have allergens on them. Swelling tends to accompany this redness, and this condition tends to affect both eyes at the same time. For those with seasonal allergies, the symptoms may only appear at certain times of the year, states the Penn State Milton S. Hershey Medical Center.
Sensitivity and Discharge
If allergies affect the eyes, then they may be sensitive to wind, light and weather. In cases of bacterial infections, there may be a clear or watery discharge. Viral eye allergies may produce pus or a creamy, thick discharge. The first step is to learn what personal triggers are and then the allergy sufferer should take steps to avoid them when possible. A doctor may prescribe antihistamines to help keep more severe symptoms under control.
Burning Sensations and Sneezing
According to the American College of Allergy, Asthma and Immunology, in some cases, the eyes may feel as if they are burning. Any of the previously mentioned symptoms may or may not be accompanied by cold-like symptoms including a runny or stuffy nose and sneezing. The sufferer may use eye drops short term for relief. A physician should evaluate chronic symptoms to determine the best treatment approach.
