简体中文Symptoms of Conjunctivitis
Redness
Pink or red discoloration of the white of one or both eyes from enlarged, more visible blood vessels.
Discharge
Watery or pus-like discharge from the eye. Bacterial infections tend to produce thicker, more copious discharge.
Itching & Burning
Persistent itching, burning, or a gritty sensation in the eye — especially common with allergic conjunctivitis.
Morning Crusting
Crusting of the eyelashes upon waking. More pronounced with bacterial infection, sometimes causing the eye to feel stuck shut.
What Causes Pink Eye?
Conjunctivitis has several distinct causes — and understanding which type you have determines the right treatment.
Viral Infection
Viral infection is the most common cause of conjunctivitis. This same virus produces the familiar red and watery eyes, sore throat, and runny nose of the common cold. Symptoms can last from one to two weeks and will then disappear on their own.
There is no antibiotic treatment for viral conjunctivitis. Supportive care — such as cool compresses and artificial tears — can help manage discomfort while it resolves.
Bacterial Infection
Bacterial infections — such as Staphylococcus or Streptococcus — cause a red eye that has a lot of pus. Some bacterial infections may be ongoing and produce little or no discharge except for mild crusting of the eyelashes in the morning.
Antibiotic eye drops are typically used to treat bacterial conjunctivitis. Both viral and bacterial conjunctivitis can be quite contagious — practicing good hygiene is essential to prevent its spread.
Allergic Conjunctivitis
Allergic conjunctivitis is not infectious or contagious. It occurs when the body is exposed to an allergen — such as pollen, pet dander, or dust — triggering an immune response in the conjunctiva, often in both eyes simultaneously.
Treatment often includes applying cool compresses to the eyes and taking antihistamines. Avoiding the allergen is the most effective long-term solution.
Environmental Irritants
Environmental irritants — such as smoke, fumes, or chemical vapors — may also cause conjunctivitis. The symptoms are usually similar to those of allergic conjunctivitis, including redness, tearing, and a burning sensation.
Removing yourself from the source of irritation is the primary step. Cool compresses and lubricating eye drops can provide relief during recovery.
Preventing the Spread
Practicing good hygiene can help prevent the spread of conjunctivitis if you are infected. The following precautions are recommended for infectious (viral or bacterial) forms.
Don't Share Towels
Avoid reusing handkerchiefs and towels to wipe your face and eyes. Use fresh, clean linens or disposable tissues each time.
Wash Your Hands
Wash hands frequently and thoroughly, especially before and after touching your eyes or applying any eye drops or medications.
Clean Contact Lenses
Properly clean your contact lenses and follow your eye doctor's guidance. Discontinue lens wear until the infection has fully resolved.
Avoid Eye Touching
Resist rubbing or touching your eyes with unwashed hands — one of the most common ways conjunctivitis spreads from person to person.
