Eye Allergies

Eye allergies are a common eye condition, often referred to as pink eye or allergic conjunctivitis. They're an inflammation of the conjunctiva, the tissue that lines the inside of the eyelid. Allergens (pollen, mold spores, pet dander, etc.), irritants (dirt, smoke, chemicals, chlorine, etc.) and even viruses and bacteria can cause conjunctivitis.

Allergy is a term that defines an abnormal reaction to dust, animal hair, pollen and other allergens. In fact, the allergy can be provoked by foods, drugs and many other substances, such as latex. This reaction is a type I hypersensitivity, which means that immunoglobulin E over stimulates the mast cells and the basophiles, eventually leading to an inflammatory reaction.

There are two primary types of allergic conjunctivitis. Seasonal allergic conjunctivitis is mostly in response to seasonal exposure to pollen from grasses, trees, and/or weeds. It's often referred to as hay fever. Perennial allergic conjunctivitis is usually the result of exposure to household allergens such as animal dander and dust mite feces throughout the year.

Eye allergies cannot harm your eyesight. They can be annoying and uncomfortable, but they cannot affect your vision.

As with most allergy treatments, eye allergies are best treated by eliminating or avoiding the allergens that are causing the problem. Unfortunately, this isn't always possible. However, there are a few steps you can take that will help minimize your exposure. Consider these ...

When pollen counts are at their worst, remain indoors as much as possible, especially during winds.
Keep your home sealed, the windows and doors closed. Make sure you change the air filters in the house.
Wear glasses or sunglasses when outdoors.
Use special bedding to minimize dust mites.
Keep a clearn house. Use a damp rag or mop to clean your floors.
If necessary, use a dehumidifier to reduce molds, especially in damp places such as basements.

Over-the-counter eye drops and oral medications often provide short-term relief of eye allergy symptoms. However, they may not relieve all symptoms. In addition, extended use of some eye drops may actually cause your condition to worsen. Discuss your eye allergy symptoms with your physician to determine which treatment option is right for you.

If it's impossible to avoid the guilty allergens and you've found oral medications and eye drops to be ineffective, your physician may suggest immunotherapy. Shots are used to inject small amounts of the allergen into your body, much the same as a vaccine. The process takes several months, with the doses gradually increasing. The goal is for your body to build up a resistance to the allergens that are causing the trouble.
