Can You Get Pink Eye from a Sinus Infection?

Quick answer: Yes. Because the sinuses sit right next to the eyes and share the same upper-respiratory lining, a sinus infection (sinusitis) can lead to pink eye, often when we rub the face and transfer bacteria or a virus to the eye. It doesn't happen with every sinus infection and is largely preventable with good hygiene.

What is pink eye?

Pink eye, clinically conjunctivitis, is inflammation of the conjunctiva (the clear membrane over the white of the eye and inner eyelid). It can be allergic, bacterial, or viral, and treatment depends on which: antibiotics for bacterial, antihistamines for allergic, and supportive care for viral.

Why a sinus infection can cause pink eye

The sinuses are hollow spaces behind the forehead, cheeks, and around the eyes. Sinusitis (bacterial or viral) causes congestion, colored discharge, headaches, and pressure around the eyes, and we instinctively rub the area, which can transfer the infection to the eye and trigger conjunctivitis.

How to prevent it

• Don't rub your face, eyes, or nose
• Wash your hands meticulously
• Dispose of tissues right after use
• Use soothing or artificial-tear drops for watering
• Drink plenty of water to thin and drain mucus

The eye, nose, throat, and lungs share one connected mucous membrane (the upper respiratory tract), which is why infections travel between them, and why pink eye can come with a cough or sore throat.

When to see an eye doctor

Pink eye is often self-limiting, but many cases need treatment, and identifying the cause is the key to clearing it. For self-care and warning signs, see how to treat an eye infection.
