Viral Vs. Bacterial Pinkeye
Pinkeye, also known as conjunctivitis, causes the clear membranes covering the eye become red and inflamed. A virus or a bacterial infection generally causes pinkeye. Other underlying diseases and allergies can also play a part in the development of pinkeye.

How it Spreads
-
Both viral and bacterial pinkeye are contagious. Pinkeye can spread due to poor hand washing, sharing an infected item, coughing, and sneezing.
Symptoms
-
Bacterial pinkeye often affects both eyes and generally causes the eyelids to swell. It can also cause a yellow-green discharge or crusty eyelids. Viral pinkeye typically starts in only one eye and within several days affects the other eye as well. Viral pinkeye symptoms include excessive tearing and clear water drainage. Both cause itchy burning eyes and sensitivity to light.

Diagnosis
-
A doctor will usually be able to diagnose pinkeye just by seeing the symptoms. However, the doctor may perform a slit lamp exam to confirm the diagnosis.
Treatment
-
Bacterial pinkeye is treated with antibiotic eye drops, pills, or ointment. There is no treatment for viral pinkeye; you must simply wait for the virus to run its course, which typically takes up to 7 days.
Relief From Symptoms
-
Apply a warm or cold compress to the eye to help remove discharge. Wipe the eye from the inside corner to the outside, and make sure to use a new cloth every time.
