Everything You Need to Know About Conjunctivitis
Pink eye also known as conjunctivitis, is a common condition that affects both children and adults. It occurs when the conjunctiva, the thin transparent tissue lining the inside of the eyelid and covering the white part of the eye, becomes inflamed. This inflammation can cause redness, discomfort, and watery or sticky discharge. While often mild, pink eye can be highly contagious when caused by viruses or bacteria. Understanding its causes, symptoms, treatment options, and preventive measures is crucial for protecting eye health and avoiding transmission to others.
Types of Pink Eye (Conjunctivitis)
Pink eye can be classified into three main types: viral, bacterial, and allergic. Each type has unique causes, symptoms, and treatment approaches.
Viral Conjunctivitis
Viral is the most common type and is highly contagious. It often accompanies symptoms of a cold, such as a runny nose, sore throat, or sneezing. People with viral conjunctivitis typically experience:
- Redness in one or both eyes
- Watery discharge
- Itchy or burning sensation
- Sensitivity to light
Viruses responsible for may include common cold viruses, adenoviruses, or in rare cases, more serious pathogens such as influenza or COVID-19. Viral usually resolves on its own within 1–2 weeks, but maintaining eye hygiene is essential to prevent spreading it to others.
Bacterial Conjunctivitis
Bacterial is less common than viral, but it can cause more noticeable discharge and eye discomfort. Typical symptoms include:
- Red, swollen eyes
- Thick yellow, green, or white discharge
- Eyes sticking together, especially after sleep
- Mild pain or irritation
Bacterial spreads easily through hand-to-eye contact or touching contaminated surfaces. Antibiotic eye drops prescribed by a healthcare provider can accelerate recovery and reduce the risk of spreading infection.
Allergic Conjunctivitis
Unlike viral and bacterial types, allergic is not contagious. It is triggered by allergens such as pollen, dust, pet dander, smoke, or chemicals. Symptoms usually include:
- Intense itching
- Redness and swelling of the eyes and eyelids
- Watery eyes
- Puffy eyelids
Treatment involves avoiding allergens when possible and using antihistamine or anti-inflammatory eye drops to reduce discomfort.
How Pink Eye Spreads
Understanding how spreads is important to prevent outbreaks, particularly in schools, workplaces, and households. The primary transmission methods include:
- Direct hand-to-eye contact after touching contaminated surfaces
- Sharing towels, pillows, or eye makeup with infected individuals
- Contact with contaminated water, such as in pools
- Improperly cleaned or shared contact lenses
Children are more prone to bacterial and viral due to frequent close contact with peers, while adults often contract from contaminated surfaces or poor contact lens hygiene.
Symptoms of Pink Eye
Symptoms can vary depending on the type of conjunctivitis. Common signs include:
- Red, bloodshot eyes
- Watery or sticky discharge
- Gritty or foreign-body sensation
- Swollen eyelids
- Itchiness, burning, or mild pain
- Sensitivity to light
- Blurred or hazy vision
Severe symptoms such as vision loss, intense pain, or blood in the eye warrant immediate medical attention.
Pink Eye Diagnosis
A healthcare provider can diagnose through a physical examination. This typically involves:
- Inspecting the eyes for redness, swelling, and discharge
- Evaluating eye movement and pupil response
- Checking vision clarity
- In severe or atypical cases, testing the eye’s surface or sending a sample of eye discharge for laboratory analysis
Proper diagnosis ensures the correct treatment and helps distinguish between bacterial, viral, or allergic causes.https://www.youtube.com/watch?v=Lb1QLr0xZv0
