Eye Allergies Types Information
There are a lot of different eye allergies types that affect over 50 million people in the United States each year. A lot of different allergies have a specific effect on the eyes, even if they aren't specifically eye allergies, but most of the ones that target the eyes directly fall under the label of allergic conjunctivitis. The conjunctiva is a thin layer made out of skin tissue that covers the eyes.
The conjunctiva is actually made out of the same types of skin cells that cover the inner surface of your nostrils. Because of this, most allergens will affect both areas at the same time. This is why you often get a runny or congested nose at the same time as red, watery eyes. Both of these are symptoms of an allergic reaction.
There are actually two primary eye allergies types. The first is known as seasonal allergic conjunctivitis, which only affects the person at a specific time of year. The second type is known as perennial allergic conjunctivitis, which can strike at any time of the year. These two types of Eye Allergies are caused when the immune system reacts to a particle in the air, commonly referred to as an allergen.
So what are allergens and where do they come from?
An allergen can be anything, as long as it triggers an allergic response in someone. The most common ones come from nature itself: pollen is easily the most aggravating substance for allergy prone individuals on the planet. When flowers release pollen, it floats through the air and we end up breathing a lot of it in.
When it comes in contact with that thin skin layer on the eyes and inner nose, it causes an allergic reaction to occur. Other allergens include weeds, grass, and pet dander, which are tiny particles of hair and skin that fall off a dog or cat.
The primary difference between the two eye allergies types, seasonal allergic conjunctivitis and perennial allergic conjunctivitis, is the time of year that you're affected and the duration of the symptoms. Seasonal allergic conjunctivitis, or SAC, usually only lasts for a relatively short time period. Your Allergy Eye Symptoms and the time of year you're affected depend on what you are allergic to.
If you were allergic to grass pollen, for example, you would probably have more Eye Allergies Symptoms in the summer. Tree pollen allergies would appear more often in the spring.
For the most part, you won't have Eye Allergy Symptoms any other time of year with SAC, especially during the winter.
Perennial allergic conjunctivitis, or PAC, is different because it usually affects you the whole year round. This is mostly due to the fact that whatever you're allergic to doesn't just pop up one time during the year.
For example, if you were allergic to pet dander, that allergen would be constantly present. Same if you are allergic to cockroaches or dust mites. These things are always around in your house, so they always affect you.
