Is springtime a difficult time for your eyes? You are not alone! The defense mechanisms put up by the body to protect eyes are quite striking. It includes the eyelids, eyelashes and the conjunctiva, which covers the eyeball. In spite of all this defense mechanism of the body, eyes continue to be one of the most sensitive organs in the human body and are always open to the attack of airborne allergens.
Tears continuously keep the eyes clean but are ineffective when
dealing with allergens. An allergy occurs due to the immune
response of the body to a foreign particle. Most of the time an
allergy is caused by the overreaction of the body. In the eyes, the
allergic reaction occurs to the conjunctiva - a transparent
membrane covering the eyeball and the under surface of the eyelid.
Dust, mold, pet dander and tree pollen are some of the most common
allergens. If you are allergic to a particular substance, and when
your eyes come into contact with the substance, it will kick start
an allergic reaction.
It is estimated that more 50 million Americans suffer from various
type of allergies. In it, majority of the people suffer from eye
allergies. People with allergic rhinitis or atopic dermatitis or
strong family history of allergy are more prone to have eye
allergies.
An allergic reaction to the conjunctiva is popularly known as
allergic conjunctivitis or 'pink eye.' It varies from soft
irritation of the eyes to severe itching, which leads to corneal
scaring. Direct contact with the allergen is the main cause of eye
allergies. The contact can happen through air, hands and from
materials used to rub the eyes.
Pollens, spores, pet dander, hair, dust, grass, mold, weeds,
certain plants, nail polish, certain medicines and secretions like
saliva are some of the most common allergens. The conjunctiva when
comes into contact with an allergen produces a chemical called
histamine, which causes the symptoms associated with eye
allergies.
Cigarette smoke, wind, perfumes, air pollution, diesel exhaust
also creates irritation to the conjunctiva but this is not included
in eye allergies.
Itching is the most important symptom of eye allergy. Redness,
watery discharge, swelling of the eyeball, tearing, burning
sensation, pain while opening eyelids after sleep, blurred vision,
pus formation and the feeling of an alien body in the eye are some
of the common symptoms. People wearing contact lens will have
discomfort in wearing it. Eye allergies mostly affect both the
eyes.
Dry eye and tear duct obstruction are sometimes confused as eye
allergies. These two types of ailments have similar symptoms to eye
allergies. Conjunctivitis can also be caused by bacteria and
viruses.
There are many treatments, but few over-the-counter medications are strong enough to help with more aggresive allergies. Zaditor is the best over-the-counter relief, but many prescription medications such as Pataday and Alrex work better for most allergies.
Eye allergies rarely cause vision impairment. Itching is the most vital symptom of allergic eyes. Although most of the eye allergies are not dangerous, persistent eye allergies should be treated and it is wise to administer drugs only after consulting Dr. Wimbish or Lollar for their advice.
