Introduction
Pink eye, medically known as conjunctivitis, is a common and often contagious condition marked by the inflammation of the conjunctiva, the transparent membrane that lines the eyelid and covers the white part of the eyeball. It can cause discomfort, but it’s typically not a threat to vision.
What is Pink Eye?
Pink eye is the inflammation of the conjunctiva, which causes the whites of the eyes to appear reddish or pink. It can result from various causes, including infections, allergies, or exposure to irritants.
Symptoms of Pink Eye
Common symptoms include:
- Redness in one or both eyes
- Itchiness and irritation
- A gritty feeling as if something is in the eye
- Discharge that forms a crust, especially at night
- Excessive tearing
- Sensitivity to light
Am I at Risk?
Anyone can get pink eye, but it’s particularly prevalent among children. Risk factors include exposure to someone infected with viral or bacterial conjunctivitis, wearing contact lenses, and having a history of seasonal allergies.
What Causes Pink Eye?
Pink eye can be caused by:
- Viruses: Including those causing the common cold.
- Bacteria: Often causing a thicker, yellowish discharge.
- Allergens: Like pollen, dust, or animal dander.
- Irritants: Chemicals (like chlorine in pools) or foreign objects.
- Blocked Tear Ducts: A common cause in newborns.
Preventing the Spread
Because viral and bacterial pink eye are highly contagious, prevention is key:
- Wash hands frequently with soap and water
- Avoid touching or rubbing your eyes
- Do not share towels, pillows, or washcloths
- Clean surfaces like doorknobs and countertops regularly
- Follow strict contact lens hygiene
When to See a Doctor
Seek medical attention if you experience:
- Severe eye pain
- Changes in vision (blurred vision or light sensitivity)
- Symptoms that persist or worsen after 24 hours
If you wear contact lenses, stop using them immediately and see an eye doctor if symptoms don’t improve within 12 to 24 hours.
Treatment for Pink Eye
Treatment depends entirely on the cause:
- Viral: Usually resolves on its own within a week or two.
- Bacterial: Often treated with antibiotic eye drops or ointments.
- Allergic: Managed with antihistamines and avoiding specific triggers.
