You won’t always know whether your pink eye occurs from bacteria, viruses, or allergens. Contacting a healthcare professional can help discover the cause of your pink eye.
If it occurs from an allergy, you may have other allergy symptoms. If you get seasonal allergies, you might notice patterns in developing allergies when you get pink eye.
A virus is the most common cause of pink eye. If you develop pink eye with a cold or another virus, it may be viral pink eye.
Bacterial pink eye usually has a more greenish-yellow discharge than the white discharge of viral pink eye.
