Conjunctivitis is when the inner lining of the eye and eyelid become inflamed. It is usually caused by a bacterial or viral infection. While conjunctivitis can happen at any age, babies and children are the most common suffers. Conjunctivitis most commonly starts in one eye and easily spreads to the other. The inflammation will make the eye extremely red, so it is also referred to as pink eye. Also associated with conjunctivitis is a yellow discharge that is thick.

This discharge can dry overnight and crust the eyelashes together, making the sufferer unable to open their eyes upon waking. This type of discharge is usually associated with conjunctivitis caused by a bacterial infection. Conjunctivitis caused by a viral infection with have a water discharge and they eyes will become very swollen. Viral conjunctivitis can also come along with other cold or flu symptoms, such a chills, fever and body aches.

Newborns can contract conjunctivitis as they pass through the birth canal if their mother suffers for an STD such as chlamydia or gonorrhea, this is referred to as neonatal conjunctivitis. In neonatal conjunctivitis, the baby will have the thick yellow discharge appear within a week of birth. Babies under two months who are suspected of having conjunctivitis need to be seen by a doctor right away. It is not worth the risk to their vision to wait for it to clear up on its own or try to remedy it at home.

Conjunctivitis can also appear because of allergens such as pollen, animal hair, preservatives in eyes drops or personal hygiene products, dust, and chemicals like solvents and paint. Allergic conjunctivitis will usually affect both eyes at once. It has many of the viral conjunctivitis symptoms including eyes that water and itch as well as an itchy, runny nose and sneezing. A foreign object that gets in the eye can produce conjunctivitis symptoms.

If it feels as if there is something in your eye and you cannot seem to get it out, consult a doctor. They can place a dye on the eye that is fluorescent that will stain it. This will allow them to see if there is an object and remove it properly. Infectious keratitis is a form of conjunctivitis that feels as if there is something in the eye and is accompanied by severe pain that makes it hard to open the eyes. If not treated promptly it can cause permanent vision damage.


Conjunctivitis is when the conjunctiva of the eye, which is a transparent layer of thin eye tissue that makes up the eyelid’s inner surface that covers the eye’s white area. Conjunctivitis is generally referred to as pink eye. The disease is very common and can be found more often in children. It can infect one or both eyes. Some types of conjunctivitis can be extremely contagious and spread easily.

Conjunctivitis is usually just an inconsequential eye infection but can lead to serious problems if not treated promptly and properly. Contagious forms are caused by viruses or bacteria infection. It can also be caused by eye irritation from allergens such as pollen, smoke, chlorine and cosmetic ingredients. What causes conjunctivitis is going to vary depending on what kind it is.

There are three types of conjunctivitis: chemical, infectious and allergic.

Chemical conjunctivitis is caused by pollutants in the air that irritate the eyes, pool cleaning chemicals such as chlorine or if the eyes are exposed to toxic chemicals.

Allergic conjunctivitis happens usually in those people who already have seasonal allergies, for example during the summer someone that comes into contact with pollen which causes an allergic reaction in their eyes. Another kind is giant papillary conjunctivitis that is caused when a foreign object is in the eye for a prolonged period of time. It happens often in those who use hard or soft contact lenses that are not changed often enough. Also to those who have a suture on the eye that is exposed or a glass eye.

There are two main categories of infectious conjunctivitis, bacterial and viral. Bacterial conjunctivitis is usually caused by either the staphylococcal or streptococcal bacteria. It can either be contracted from your own respiratory system of skin but also from contact with others who are infected, insects, using makeup or lotions that are contaminated and by poor hand washing practices. A severe type of bacterial conjunctivitis is ophthalmia neonatorum, which is found in newborns. This severe eye condition occurs when babies are exposed to gonorrhea or chlamydia whilst being born.

Viral conjunctivitis is caused most often by the very contagious virus that goes along with the common cold. People’s eyes get exposed to this virus through being exposed to sneezing and/or coughing by those who are infected with the virus in the respiratory area. It can also be spread through the virus being contained in the mucous membranes that connect through the lungs, nose, conjunctiva and tear ducts.


Conjunctivitis is an inflammation of the lining of the eye tissue. It is one of the most treatable and common eye problems found in adults and children. It can easily be triggered by allergens which are the substances that cause allergic reactions. There are other causes as well including viruses, bacteria and STDs which are all contagious conjunctivitis caused by allergies, however, is not contagious. Knowing what has caused the conjunctivitis is important because each type has different treatments.

The symptoms of conjunctivitis caused by allergies are:
• The whites of the eyes or inner lid will be red
• Watery eyes
• Severe itching
• Eyelids may swell

If you have any of these symptoms than please see an optometrist, who is also trained in eye problems or even a family doctor can properly diagnose conjunctivitis and what is causing it. Conjunctivitis caused by allergies will clear up with the treatment of antihistamines or if the allergen that is causing the reaction is removed. There are several topical treatments a doctor may suggest.

Ocular decongestants help to lower the amount of redness because they constrict the blood vessels in the eye. They cannot be used on long term basis and using for more than just a few days can actually make matters worse. Ocular antihistamines also help reduce redness as well as the itching and swelling associated with allergic conjunctivitis. They work by stopping the histamines from being able to communicate with the brain and cause the allergic reaction. They can be obtained by prescriptions or over the counter. If other medications are not working a doctor can prescribe ocular steroids. They have to be used only under close doctor supervision since it is possible for them to cause increased eye pressure and damage vision. Ocular steroids can increase the chances of cataracts, lens clouding and other issues.

There are ways to help reduce the symptoms of conjunctivitis caused by allergies while waiting for it to clear up. Contacts must not be worn until completely cleared. Cold compresses can help with inflammation and itching. Over the counter eye drops that are labelled artificial tears can help stop the burning and itching. Be sure they are these types of drops because other kinds can cause more irritations. Also if the other eye is not infected do not use the same bottle on that eye. The best thing that can be done is to prevent allergic conjunctivitis by avoid allergens that can trigger it.
