Conjunctivitis, commonly called “pink eye”, is a widespread eye condition that impacts people of all age groups, from toddlers to seniors. Whether you\u2019ve personally experienced conjunctivitis or have a friend or family member who has, you know how frustrating it is to deal with.<\/p>\n\n\n\n

Despite how common it is, many individuals remain unclear about what conjunctivitis is, how it occurs, and how to seek proper treatment. So, let\u2019s look at the causes and symptoms, and provide insights about effective treatment.<\/p>\n\n\n\n

What is Conjunctivitis?
<\/strong>Conjunctivitis is the inflammation of the conjunctiva, a delicate and transparent layer that envelops the white portion of the eye (sclera) and lines the inner surfaces of the eyelids. One or both eyes may be watery, sore or itchy, sometimes with sticky white or yellow discharge. The affected eye, or eyes, will also look puffy.<\/p>\n\n\n\n

The term \u201cpink eye\u201d can be traced back to the visible redness or pinkish tint that becomes apparent when the blood vessels within the conjunctiva become dilated and inflamed. However, it\u2019s important to note that not all cases of conjunctivitis result in the characteristic redness; the severity and manifestation of symptoms can differ.<\/p>\n\n\n\n

How Does Conjunctivitis Happen?
<\/strong>Conjunctivitis can occur for various reasons, each with its own set of causes and risk factors. Understanding these causes plays a vital role in determining the right treatment and mitigating the transmission of the condition.<\/p>\n\n\n\n

Viral conjunctivitis: This form of pink eye is typically caused by viruses, such as adenoviruses responsible for various respiratory illnesses. It can also result from the same virus responsible for the common cold. Viral conjunctivitis is exceptionally contagious and can spread through contact with infected eye secretions or contaminated surfaces. It often starts in one eye and may progress to the other.<\/p>\n\n\n\n

Bacterial conjunctivitis: Bacteria like Staphylococcus aureus, Streptococcus pneumoniae, or Haemophilus influenzae commonly cause bacterial conjunctivitis. This type of pink eye can result from poor hygiene, using contaminated cosmetics, poor contact lens hygiene, or coming into contact with an infected person\u2019s eye discharge. It typically affects one eye but can spread to
the other.<\/p>\n\n\n\n

Allergic conjunctivitis: Allergic conjunctivitis occurs when the conjunctiva reacts to allergens, like pollen, dust mites, pet dander, or certain chemicals. It is not contagious and often affects both eyes simultaneously. Seasonal allergies are a common trigger for this form of conjunctivitis.<\/p>\n\n\n\n

Chemical conjunctivitis: Exposure to irritating substances, such as chlorine in swimming pools, smog, or harsh chemicals, can lead to chemical conjunctivitis. This form of pink eye typically impacts both eyes and occurs due to direct contact with the irritant.<\/p>\n\n\n\n
