What is Conjunctivitis?

Pink eye is an inflammation of the transparent membrane that lines the eyelid and eyeball. This membrane is called the conjunctiva.

Pink eye also is called conjunctivitis. (MAYO CLINIC)

Conjunctivitis, also referred to as pink eye, is an inflammation of the conjunctiva, the thin, transparent covering that lines the inside of the eyelids and covers the white area of the eye. Although it can affect anyone, children are more frequently affected than other age groups. Allergies, germs, viruses, or irritants are just a few of the causes of conjunctivitis. 

When an allergen, such as pollen or pet dander, comes into contact with the eyes, allergic conjunctivitis develops. Usually, it results in itchiness, redness, and excessive crying.

Bacterial conjunctivitis is brought on by bacteria and frequently results in coated eyelashes and a yellow or green discharge. It is extremely contagious and is brought on by a virus, like the common cold. Redness, pain, and watery discharge are possible effects. 


Causes of Conjunctivitis 

Numerous things can lead to conjunctivitis, so figuring out what caused it is essential to choose the best course of action. Conjunctivitis is frequently brought on by allergies, which are brought on by allergens like pollen, dust mites, or pet dander.

Infections caused by bacteria or viruses that enter the eye and inflame it can also result in conjunctivitis. Conjunctivitis can also be caused by irritants like smoke, chemicals, or foreign objects irritating the conjunctiva. 

Conjunctivitis occasionally manifests as a side effect of underlying conditions such autoimmune disorders like rheumatoid arthritis, blepharitis, or dry eyes. Conjunctivitis risk can also be increased by poor hygiene habits including exchanging infected towels or eye makeup or touching the eyes with unwashed hands.

There are several types of conjunctivitis, each with its own distinct characteristics.


Allergic conjunctivitis is frequently seasonal and is brought on by allergens. It results in scratching, bruising, and frequent crying. 

Bacterial conjunctivitis can cause matted eyelashes, a yellow or green discharge, and is brought on by bacteria. 

Viral conjunctivitis, on the other hand, is highly contagious and frequently accompanied with cold or flu symptoms. It can cause runny discharge, redness, and discomfort.

Giant papillary conjunctivitis Another type of conjunctivitis is large papillary conjunctivitis, which is frequently induced by contact lens usage or an artificial eye prosthetic. It causes big lumps to grow on the inner surface of the eyelids and can cause blurred vision.

Neonatal conjunctivitis; a disorder known as neonatal conjunctivitis affects babies and is frequently caused by an infection transferred during childbirth.


Symptoms of Conjunctivitis 

Recognising conjunctivitis symptoms is critical for early detection and treatment. Redness of the eye or inner eyelid, itching or irritation, excessive tearing, a gritty sensation in the eye, and a discharge that may be watery, yellow, or green are the most frequent symptoms of conjunctivitis. Swollen eyelids, sensitivity to light, hazy vision, and the sensation of something in the eye are also possible.

How to Prevent Conjunctivitis?

Preventing conjunctivitis involves practicing good hygiene and taking precautions to reduce the risk of exposure to potential irritants or infectious agents. Here are some preventive measures to consider: 


Hands should be washed with soap and water on a regular basis, especially before touching your eyes or using eye drops.

Lubricating eye drops: These can provide brief relief from the dryness and discomfort associated with conjunctivitis. However, before using any eye drops, you should contact a healthcare expert, especially if you have pre-existing eye issues or are taking other medications.

Warm compresses: Applying a warm compress to the afflicted eye might help decrease pain and swelling. Soak a clean cloth in warm water, wring it out, and gently apply it over the closed eyes for a few minutes.

Saline solution: Rinsing the eyes with a saline solution might help cleanse the afflicted region and relieve irritation. A teaspoon of salt and a cup of distilled water should be combined, boiled, and allowed to cool before using to clean the eyes.



It’s worth noting that home remedies may not be sufficient to treat the underlying cause of conjunctivitis, especially in cases of bacterial or viral infections. Therefore, it is crucial to consult with a healthcare professional for a proper diagnosis and appropriate treatment.


Medical Treatments for Conjunctivitis 

Medical treatments for conjunctivitis vary depending on the underlying cause of the condition. If the conjunctivitis is caused by bacteria, your healthcare provider may prescribe antibiotic eye drops or ointments to eliminate the infection.

For viral conjunctivitis, there is no specific drug is available. However, your healthcare professional may offer supportive steps to relieve symptoms, such as using lubricating eye drops, applying cool compresses, and practising good hygiene to prevent the virus from spreading.

In situations of allergic conjunctivitis, recognising and avoiding the allergen is critical. Your doctor may prescribe antihistamine eye drops or oral drugs to lessen the allergic response and relieve symptoms. It may also be beneficial to apply cold compresses and avoid rubbing the eyes, as this might aggravate the symptoms.
