As flu season descends upon us, an unexpected companion emerges: pink eye. The viruses responsible for the flu, the common cold, and even COVID-19 can manifest in the eyes, presenting an additional dimension to the seasonal health concerns. Conjunctivitis, more commonly known as pink eye, becomes a potential consequence, giving the eyes a distinctive pink or reddish hue along with accompanying symptoms such as irritation, itchiness, and discharge.

Dr. Jennifer Tsai, an optometrist based in New York City, sheds light on the connection between viral infections and eye-related symptoms. She notes, “When you have a viral infection, that can lead to eye-related symptoms, especially if you touch the eye or you’re around someone that has it and they’re coughing or sneezing.” Pink eye can manifest either through the spread of a virus from one’s own mucous membranes under attack or through exposure to someone with a respiratory infection.

Navigating this unique intersection of flu and eye health involves recognizing the types of eye infections that may surface during the flu season. Equally important is understanding how to provide relief at home and knowing when it’s crucial to seek professional medical attention. In a season rife with health concerns, being informed about potential eye complications adds an extra layer of preparedness to safeguard one’s overall well-being.

What viruses can cause pink eye? 

The most familiar seasonal viruses can all cause viral pink eye. Some research from 2021, for example, found that as many as one in 10 people with COVID-19 experienced eye symptoms, although the American Academy of Ophthalmology says conjunctivitis from coronavirus is much more common in children than it is in adults. 

Tsai says that the most common cause of viral pink eye is infection with the adenovirus, a virus that causes mild cold or flu symptoms in most people, which also spreads more widely during flu/respiratory virus season. Lesser-known viral culprits of pink eye also include the herpes simplex virus, the virus that causes cold sores, Tsai said. This can spread if virus from a cold sore touches the eye, or it can reoccur in outbreaks. 


Understanding the Distinct Symptoms: Viral vs. Bacterial Pink Eye

In the realm of pink eye, distinguishing between viral and bacterial symptoms is pivotal. Dr. Tsai sheds light on the characteristics of each, revealing that viral pink eye often includes itching, watery discharge, redness, and burning. Notably, this variant tends to affect both eyes, rapidly spreading from one to the other. Conversely, bacterial pink eye, rooted in infection or injury, may feature a thicker, yellowish discharge, intensified eye pain, and blurry vision. Dr. Tsai emphasizes the diagnostic significance of bacterial pink eye occurring predominantly in one eye.

Navigating Treatment Paths: Home Relief and Professional Intervention

The management of pink eye hinges on its origin. While viral cases are often self-limiting, resolving within two weeks, bacterial infections may necessitate antibiotic eye drops. Seeking timely medical consultation is crucial, particularly if experiencing eye pain, vision disturbances, or signs of a severe eye infection. Dr. Tsai underscores the importance of consulting an eye doctor for comprehensive guidance, regardless of the severity or causative factor of pink eye.

At-Home Strategies for Soothing Pink Eye Symptoms

For those managing pink eye at home, Dr. Tsai offers practical tips. These include the use of a cold compress for comfort, artificial tears to alleviate eye discomfort, and allergy drops if itching persists due to allergies. Amid eye drop recalls, caution is advised, and Dr. Tsai recommends avoiding drops that don’t meet safety standards. Additionally, she suggests steering clear of certain brands, such as Visine and Clear Eyes, which contain ingredients that can constrict blood vessels in the eyes.

Preventing Pink Eye Spread: Best Practices for Eye Hygiene

Preventing the spread of pink eye is as crucial as managing its symptoms. Adhering to guidelines from reputable sources such as the American Optometric Association and the American Academy of Ophthalmology is paramount. These include refraining from reusing towels, avoiding eye contact, promptly washing hands if contact occurs, abstaining from makeup during an eye infection, and temporarily discontinuing the use of contact lenses until the infection resolves.
