What Causes Pink Eye?

Learn what causes pink eye, see pink eye pictures and get tips on how to both prevent and cure conjunctivitis.

Pink eye occurs when you have an eye infection and the blood vessels on the clear membrane, that covers the white of your eye, dilate and cause your eye to become red or pink.

The infection, more properly known as conjunctivitis, can be contagious. A virus could cause it, for example, or bacteria could get into your eye, making it red, blotchy and painful. Non-contagious forms of pink eye are most often caused by a reaction to something getting into the eye, such as dust or smoke, or you may be allergic to high levels of pollen in the air.

Contagious Period - What Causes Pink Eye

Young people are especially prone to eye infections when colds are doing their rounds. Lots of coughing and sniffing spreads viral forms of conjunctivitis quickly. The contagious period for what causes pink eye is usually between 3 and 5 days after diagnosis, but you should check with your doctor, so that your child can be kept at home to prevent infecting other children.

While many parents these days tend to be over-protective of their kids and almost over-sanitize the environment around them, what causes pink eye is often simple things like using the same towel or not washing hands properly. So impressing good standards of hygiene on your kids is key.

In the case of contact lens wearers, of course, poor hygiene is often a cause of pink eye, together with the use of extended wear contact lenses which can harbor bacteria underneath the lens for long periods of time.

If you get pink eye, you should stop wearing your lenses and, if your disposable lenses still have time to run, discard them for a new pair, as cleaning and disinfecting won't necessarily remove all traces of the bacteria that may well have caused the red eye symptoms in the first place.
