What is Pink Eye?

Pink eye is an inflammation or infection of the conjunctiva, the transparent membrane that lines your eyelid and covers the white part of your eyeball. When this membrane becomes inflamed, the blood vessels become more visible, giving the eye a pink or reddish appearance.

Pink eye can appear suddenly due to several factors:

Viral or Bacterial Infection: Exposure to viruses or bacteria can cause rapid onset conjunctivitis.
Allergic Reactions: Allergens like pollen or pet dander can trigger inflammation quickly.
Irritants: Smoke, chlorine in swimming pools, or foreign objects can irritate the eye.
Contact Lens Use: Improper hygiene or extended wear can lead to infection.
