All You Need to Know About Pink Eye: An Introduction

| 14,368 views

Your eye is composed of different parts that all work together in synergy to give you clear vision. But there is one important part that rarely gets talked about — the conjunctivas, or the mucous membranes that cover each of your eyes.

The role of the mucous membranes is to provide protection from foreign objects and help prevent your eyes from drying up due to constant exposure to the outside world.

You’ll find other organs covered with mucous membranes as well, such as your mouth, ears and your respiratory tract.1 Like your eyes, these organs are constantly exposed to foreign elements from the outside world.

But what happens when a conjunctiva becomes infected due to a virus or chemical exposure? You will most likely experience a condition known as pink eye.

Pink Eye: One of the Most Common Eye Infections

Pink eye is the colloquial name for conjunctivitis, which is the clinical term for conjunctiva inflammation. Around 3 million cases of pink eye are documented annually in the U.S. alone,2 with children being the largest demographic.3

However, anyone can get pink eye, including newborn infants.4 Below are the underlying causes of pink eye:5

Viruses: Several types of viruses are known to cause pink eye, but the adenovirus is the most prominent group. It’s a family of viruses that specifically targets mucous membranes, causing not only pink eye but contagious respiratory illnesses such as the flu or the common cold as well.

Bacteria: Similar to viruses, certain strains of bacteria can cause contagious pink eye. Examples include the Staphylococcus aureus and Streptococcus pneumonia strains.

Allergies: Pink eye may develop as an allergic reaction to allergens such as animal dander, dust, molds or pollen.

Chemicals and other foreign objects: Exposure to chemical fumes such as smoke from a vehicle exhaust may cause inflammation. Meanwhile, wearing contact lenses incorrectly or even a stray eyelash may cause pink eye.

How Pink Eye Is Spread and What It Looks Like

One of the main causes of pink eye is simply poor hygiene practices. Habits such as sharing towels and infrequent hand washing can spread viruses to other people. Sneezing and coughing without closing your nose and mouth can spread microorganisms easily as well, especially if you currently have a cold.6

If you do happen to get pink eye, the first thing you’ll notice is that the affected eye will become red and swollen. It may also come with a burning feeling and a strong, itching sensation. Discharge and crusting is also common. If you’re not careful where you place your hands, you may end up infecting your other eye as well.
