today's topic is eye allergies
an eye allergy is an immune response
that occurs when the eye comes in
contact with an irritating substance
known as allergy the function of the
immune system is to defend the body
against harmful invaders such as
bacteria and viruses
in an eye allergy the immune system
mistakes an allergy
for a dangerous substance causing the
immune system to overreact
and produce antibodies called
immunoglobulin or ige
these antibodies travel to the cells in
the eye and in turn
cause it to release histamines and other
chemicals
in an effort to protect the eyes
it is this chemical reaction that causes
the symptoms associated with the
condition

the year
