Pink eye, or conjunctivitis, is an inflammation or infection of the conjunctiva, the thin, transparent membrane covering the white part of your eye and the inside of your eyelids. It causes redness, itchiness, and often a discharge.
Types of Pink Eye
There are three main types: viral, bacterial, and allergic. Viral conjunctivitis is the most common, usually caused by common cold viruses. It’s highly contagious and often clears up on its own within a week or two. Bacterial conjunctivitis, often caused by bacteria like Staphylococcus aureus or Haemophilus influenzae, may require antibiotic treatment. Allergic conjunctivitis results from an allergic reaction to substances like pollen or pet dander. This type is not contagious.
Symptoms of Pink Eye
Common symptoms include redness in one or both eyes, itchiness, burning, and a gritty feeling. You might also experience a watery or pus-like discharge, depending on the cause. In some cases, you may experience swollen eyelids or light sensitivity.
When to See a Doctor
Seek medical attention if you experience severe pain, vision changes, significant swelling, or if symptoms don’t improve after a week or worsen. A doctor can properly diagnose the type of conjunctivitis and recommend the appropriate treatment. Note that pink eye is highly contagious – good hand hygiene is paramount to preventing its spread.
