Conjunctivitis (Pink Eye)

Conjunctivitis, Better Known as Pink Eye

You may not have heard of conjunctivitis but you’ve certainly heard of pink eye. This common eye condition is also known as red eye, and, if due to a viral infection, is the ocular version of the common cold.

What is Conjunctivitis?

Conjunctivitis refers to a group of eye conditions, all categorized by inflammation of the conjunctiva, or the membrane on the inside of the eyelid and outside of the eye. In short: your eyes become red, puffy, and may be itchy. Discharge is also a very common symptom. There are a number of types of conjunctivitis, so it’s important to have your eyes properly diagnosed so you can undertake the right treatment.

Types of Conjunctivitis

This form of pink eye is like any typical allergic reaction, except it occurs in your eye. Your immune system respond to harmless stimuli as though it was dangerous. It is trigger by a variety of environmental and household irritants like pet dander, pollen, and dust. Your eyes will become watery and itchy. These symptoms are usually joined by sinus congestion or a runny nose.


Over the counter allergy medications typically work well to reduce the severity of allergic conjunctivitis flare-ups. This type of conjunctivitis is often seasonal. Talk to your optometrist about the best treatment option for you.

Viral conjunctivitis is caused by a virus and is highly contagious. Your eyes may become sensitive to light along with the typical pink eye symptoms including watering and discharge. This virus is airborne and can be transmitted by sneezing or coughing. Those with suspected viral conjunctivitis should refrain from going to work or school and instead immediately seek medical attention to confirm the diagnosis.


Viral conjunctivitis will resolve on it’s own. Your body is designed to fight off viruses and this one is no different. However, it’s extremely important for you to seek out a proper medical diagnosis to ensure you do not have bacterial conjunctivitis.

Bacterial conjunctivitis is considered the traditional type of pink eye. It is caused by detrimental bacteria that have infected the eye, and can easily spread from one eye to the other. This bacteria can come from other infections such as a sinus infection or from bacteria on dirty hands. This form of conjunctivitis is characterized by red, swollen eyes and a yellowish or greenish discharge, which may be so thick the eyelids are stuck shut in the morning.


Antibiotics are necessary to treat bacterial conjunctivitis. Usually, these antibiotics are prescribed by your optometrist in eye drops or ointments, but for some bacterial sources, oral medication may be required. Washing sheets, towels, or blankets that may have come into contact with the infected eye is vital to reducing the risk of reinfection, and to reduce the threat to siblings or other family members in the home. Refrain from going to work or school with pink eye.
