Allergies can take on many forms, and they are different for everyone.Seasonal allergies are quite possibly the most well known. This form is most often associated with plant pollens and typically will affect you during the spring.Perennial allergies, on the other hand, are noticed year-round. These allergens are typically due to indoor elements such as animal dander and insect proteins.
You may notice during these times that your eyes tear more often and, in fact, your tears play a very important role in both allergic conditions and dry eye. When the surface of your eye detects an allergen or becomes unstable due to dryness, reflex tearing occurs and your eyes begin to water.
This reflex tearing occurs because the eye is calling for tears to flush out the allergens and protect the ocular surface. Although annoying, these tears can be helpful in flushing away allergic material and reducing the contact time with your eye, minimizing the allergic response. However, the unstable surface of the eye must still be treated to prevent the condition in the first place.
Why Are My Eyes Dry and Itchy?
There are so many reasons for dry, itchy eyes, but since you're here reading about allergies, there's a good chance this is the cause for you. This is the first cause we think of when you have itchy eyes. Pollen is the number one instigator, but grass, trees, and weeds can all contribute to both seasonal and perennial allergies.
Pet dander is another common cause of allergies, and so is mold. These can both be found readily in many homes and contribute to perennial allergies.
Some allergy sufferers also notice that they react to other things, such as cigarette smoke. If you're a smoker or have one in your home, you should make an attempt to quit for the comfort and health of both you and those around you.
Lastly, perfumes, cosmetics, and household cleaners and detergents can all contribute to allergies. If you're suffering from allergic symptoms but it seems to be something other than pollen, take a look at the products you're using on a daily basis.
