Conjunctivitis | Pink Eye-Causes
Bacterial conjunctivitis is often caused by bacteria such as staphylococcus and streptococcus.
- The viral type is often associated with an upper respiratory tract infection, cold, or sore throat.
- A history of close contact with a family member or any other individual with a "pink eye" is also commonly elicited.
- Allergic conjunctivitis may be caused by intolerance to substances such as cosmetics, perfume, or drugs.
- Environmental irritants such as smoke or fumes may cause conjunctivitis or pink eye.
- Any type of conjunctivitis or pink eye is aggravated by dryness of the eyes.
- Conjunctivitis or pink eye may be transmitted to the eye by contaminated hands, washcloths or towels, cosmetics (particularly eye makeup), false eyelashes or improper usage of contact lenses.
- Newborns can be infected by bacteria in the birth canal. This condition is called Ophthalmia Neonatorum and must be treated immediately to preserve sight.
