Pink eye, also known as conjunctivitis, is a common eye condition that causes redness and irritation of the eye. While many cases are mild and resolve on their own, some forms of pink eye require medical evaluation and treatment.
What Is Pink Eye?
Pink eye is inflammation of the conjunctiva, the thin, clear tissue that covers the white part of the eye and the inside of the eyelids. It can affect one or both eyes. When the conjunctiva becomes irritated or infected, blood vessels in the eye become more visible, causing the eye to appear pink or red. Pink eye can be caused by infections, allergies, or exposure to irritants.
What Causes Pink Eye?
Common causes include:
- Viral infections, including those associated with colds
- Bacterial infections
- Seasonal allergies
- Smoke, dust, or chemical irritants
- Contact lens use or improper lens hygiene
Viral and bacterial conjunctivitis can be contagious, while allergic conjunctivitis is not.
What Are the Symptoms of Pink Eye?
Common signs and symptoms include:
- Red or pink appearance of the eye
- Itching or irritation
- Excessive tearing
- Eye discharge
- Crusting around the eyelids, especially after sleep
- Burning sensation
- Sensitivity to light
- Feeling like something is in the eye
Allergic pink eye often causes significant itching, while bacterial infections may produce thicker discharge.
How Is Pink Eye Treated?
Treatment depends on the cause of the condition. Some cases improve without medication, while others may require medical treatment.
Possible treatments include:
- Artificial tears for symptom relief
- Cold compresses to reduce discomfort
- Avoiding allergens or irritants
- Prescription antibiotic eye drops for bacterial infections
- Allergy medications for allergic conjunctivitis
To prevent spreading contagious forms of pink eye, avoid sharing towels, wash your hands
frequently, and avoid touching your eyes.
