Conjunctivitis, commonly known as pink eye, is a condition that affects the conjunctiva, the thin, clear tissue that lines the inner surface of the eyelid and covers the white part of the eye.


Conjunctivitis can manifest with various symptoms, which may include:
Redness in the white of the eye or inner eyelid
Discharge (yellow, green, or white)
Itching or burning sensation
Blurry vision
– Increased sensitivity to light


Conjunctivitis can be caused by a variety of factors, such as:
1. Viral Infection: Common viral infections, such as the adenovirus, are a frequent cause of conjunctivitis.
2. Bacterial Infection: Bacterial conjunctivitis can be caused by bacteria such as Staphylococcus aureus and Streptococcus pneumoniae.
3. Allergic Reaction: Allergens like pollen, dust mites, or pet dander can trigger allergic conjunctivitis.
4. Irritants: Substances like smoke, chlorine in pools, or shampoos can irritate the eyes, leading to irritant conjunctivitis.
5. Foreign Body: When a foreign object enters the eye, it can cause irritation and conjunctivitis.
6. Contact Lenses: Improper use or poor hygiene of contact lenses can lead to contact lens-related conjunctivitis.


Your eye doctor can diagnose conjunctivitis through a comprehensive eye examination, which may include:
– Visual acuity testing
– Eye pressure measurement
– Examination of the inner structures of the eye
– Evaluation of the symptoms and medical history


Treatment for conjunctivitis depends on the cause:
1. Viral Conjunctivitis: Typically, viral conjunctivitis does not require treatment and resolves on its own. Cool compresses and artificial tears can help alleviate symptoms.
2. Bacterial Conjunctivitis: Antibiotic eye drops or ointments may be prescribed to clear the infection.
3. Allergic Conjunctivitis: Antihistamines, mast cell stabilizers, or corticosteroids can help manage allergic reactions.
4. Irritant Conjunctivitis: Avoiding the irritant and using artificial tears can provide relief.
5. Foreign Body Conjunctivitis: Removing the foreign body and using prescribed eye drops may be necessary.
6. Contact Lens-Related Conjunctivitis: Proper hygiene, changing contact lenses as directed, and using lubricating eye drops can help prevent conjunctivitis.


To prevent conjunctivitis, consider these tips:
– Wash your hands regularly, especially before touching your eyes.
– Avoid touching or rubbing your eyes.
– Do not share towels, pillows, or eye makeup to prevent the spread of infection.
– Replace contact lenses as per the schedule and practice good contact lens hygiene.
– Protect your eyes from irritants and allergens by wearing safety glasses or avoiding allergens.
