Pinkey

Conjunctivitis, commonly known as pink eye, is an inflammation or infection of the outermost layer of the white part of the eye and the inner surface of the eyelid. It makes the eye appear pink or reddish, hence the name. There are three main types of conjunctivitis: viral, bacterial, and allergic.

Causes

Conjunctivitis can be caused by:

• Viral infections, often associated with the common cold.
• Bacterial infections, which can come from a variety of bacteria.
• Allergies, related to allergens like pollen, dust mites, or pet dander.
• Irritants such as chlorine in swimming pools, smoke, or dirt can also cause a non-infectious form of conjunctivitis.

Symptoms

Common symptoms of conjunctivitis include:

• Redness in one or both eyes
• Itchiness in one or both eyes
• A gritty feeling in one or both eyes
• A discharge in one or both eyes that forms a crust during the night
• Tearing

Transmission

Viral and bacterial conjunctivitis can be highly contagious. They are usually spread through direct or indirect contact with the liquid that drains from the eye of someone who's infected. Precautions such as washing hands frequently and avoiding touching the eyes can help prevent its spread.

Treatment

Treatment of conjunctivitis depends on the cause:

• Viral conjunctivitis usually resolves on its own without treatment. Symptomatic treatments, such as using a cold compress, can help relieve discomfort.
• Bacterial conjunctivitis is typically treated with antibiotic eye drops or ointments.
• Allergic conjunctivitis is treated by avoiding the allergen whenever possible and may include antihistamines, decongestants, and/or steroid eye drops.

Prevention

Preventive measures include:

• Practicing good hygiene, such as frequent hand washing
• Avoiding touching or rubbing the eyes
• Using a clean towel and washcloth daily
• Not sharing personal items like towels, washcloths, and eye makeup
