There are multiple types of conjunctivitis (otherwise known as pink eye) - viral, bacterial and allergic.
Viral conjunctivitis may clear up on its own, but it’s best to ask your doctor or pharmacist to see what is causing the infection.
You may need an antibiotic ointment if the cause is bacterial by using a treatment such as GoldenEye Antibiotic Ointment which can help to ease the condition in as little as 5 days.
You might also wish to use a product to create artificial tears like Liquivisc Eye Gel which can relieve any dryness and inflammation caused by conjunctivitis.
