Conjunctivitis (Pink Eye)

What is it? Conjunctivitis is inflammation of the conjunctiva—the thin, transparent membrane that lines the inner eyelids and covers the white part of the eye (sclera). When irritated or infected, the tiny blood vessels in this tissue become engorged and visible, giving the eye a characteristic pink or red appearance. There are three primary types: Viral conjunctivitis (most common, highly contagious, often associated with colds), Bacterial conjunctivitis (caused by bacteria like Staphylococcus or Streptococcus, produces thick discharge), and Allergic conjunctivitis (triggered by allergens like pollen, dust, or pet dander, not contagious). Chemical irritants, foreign bodies, or contact lens overwear can also cause non-infectious conjunctivitis.

Common Symptoms

  • Redness in one or both eyes
  • Itching, burning, or gritty sensation
  • Watery or thick, yellow-green discharge that may crust eyelashes overnight
  • Tearing and light sensitivity
  • Swollen eyelids
  • Blurred vision that clears with blinking (due to discharge)
  • Feeling of a foreign body in the eye

Risk Factors

  • Close contact with someone who has infectious conjunctivitis
  • Allergies (seasonal or perennial)
  • Contact lens wear, especially improper hygiene or overnight use
  • Upper respiratory infections (for viral type)
  • Exposure to irritants: smoke, chlorine, fumes
  • Weakened immune system

Treatment Options

  • Viral: Supportive care—cold compresses, artificial tears, strict hygiene. Usually resolves in 1–2 weeks.
  • Bacterial: Prescription antibiotic eye drops or ointments (e.g., erythromycin, fluoroquinolones). Symptoms often improve within 24–48 hours.
  • Allergic: Antihistamine/mast-cell stabilizer drops (e.g., olopatadine), oral antihistamines, cold compresses, allergen avoidance.
  • General Care: Discontinue contact lens wear until resolved; replace lenses and case afterward. Avoid sharing towels, pillows, or eye makeup.

Prevention & Lifestyle Tips

  • Wash hands frequently with soap and water, especially after touching your face.
  • Avoid touching or rubbing your eyes.
  • Replace eye makeup regularly and never share cosmetics.
  • Follow proper contact lens hygiene: clean, store, and replace as directed.
  • For allergies: keep windows closed during high pollen seasons, use air filters, shower after outdoor exposure.

When to See a Doctor Consult an ophthalmologist if you experience severe pain, light sensitivity, vision loss, symptoms lasting more than a week, or if you wear contact lenses and develop redness. Doctor's Note: While "pink eye" is often mild, it can mimic more serious conditions like uveitis or acute glaucoma. Never use leftover antibiotic drops without a diagnosis—misuse can worsen certain infections or cause resistance. If in doubt, get it checked.
