Pink eye, an unsightly condition affecting the whites of a person’s eyes, is an inflammation of the transparent lining that covers the eye. Small blood vessels contained within the lining become infected and inflamed, making them appear more visible and the whites of the eyes to take on a pink or reddish hue.
Information. Pink eye can be caused by a bacterial or viral infection, an allergic reaction, or in the case of some infants, a blocked tear duct. While pink eye can be mildly irritating, it does not generally affect a person’s ability to see. Several treatments are effective at reducing inflammation and itchiness associated with the condition. Because pink eye is highly contagious, early diagnosis and treatment are essential to keep bacteria and infection from spreading further.
