Most of us are concerned about becoming infected with COVID-19 via our hands, nose, and mouth. However, there is another way the virus can make its way into our system, and it is right in front of—or more specifically, inside of—our eyes. Here are 7 ways coronavirus can enter your eyes, as well as tips on how to prevent it from happening.
You’re Rubbing or Touching Your Eyes
“The most common way for COVID to enter through the eyes is by touching your face or rubbing your eyes after your hands have come into contact with an infected surface,” Dr. Kevin Lee, eye physician & surgeon from the Golden Gate Eye Associates within the Pacific Vision Eye Institute in San Francisco, explains to Eat This, Not That! Health. “People don’t realize how often they touch their face, so please be cognizant.”
The Rx: “Avoid rubbing your eyes or touching your face especially after contact with public surfaces.”
You’ve Been Exposed to Aerosol Transmission
Since COVID has the ability to spread by aerosol transmission and respiratory droplets, Dr. Lee points out that just being in the vicinity of an infected person can actually result in transmission through the eyes. “For instance, if someone who has the coronavirus sneezes, the droplets can actually enter through the eyes,” he explains.
The Rx: How can you prevent this from happening? Dr. Diaz suggests wearing glasses, in order to create a physical barrier, “which may block droplets from reaching the eye,” he explains. “In that sense, they function as ‘safety glasses’ which we use for various activities and occupations.”
You Wear Contact Lenses
You might want to think about swapping out your contact lenses with glasses until the coronavirus pandemic is over, urges Dr. Lee. “Contact lens wearers have a higher risk of transmitting the virus through their eyes.” This is especially true if contact lense-wearers do not practice good hygiene such as not properly cleaning their lenses, sleeping in contacts, not washing their hands, or extending the wear of their contacts past the recommended date.
The Rx: At the very least, practice good contact lens hygiene. Better yet, wear glasses.
You’re Sharing Eye Drops or Cosmetics
Sharing products that make contact with the eyes—ranging from eye drops to mascara—can put you in direct contact with the virus. “Coronavirus can be found and transmitted through ocular secretions, like tears, so it has the ability to enter the eyes through products like cosmetics and eye drops,” explains Dr. Lee. “It’s possible for the tip of the eye dropper or mascara to be contaminated by coming in contact with the ocular secretions of someone who is COVID positive.”
The Rx: He urges the importance of not sharing eye drops or cosmetics with family members or friends. Additionally, if you’ve used any products while experiencing COVID-like symptoms, “be sure to throw the products away as they’ve likely been contaminated.”
You Have Allergies
If you are one of the millions of people who suffer from allergies, Vicente Diaz, MD, MPH, a Yale Medicine ophthalmologist, points out that it is a good idea to do everything you can to control them. “This can prevent rubbing the eyes, which can be tempting when a reaction to pollen causes them to itch,” he explains.
You’re Sharing Towels and Pillows
The Rx: “Avoid using bathroom hand towels on your face, and be sure to clean them regularly.” Keep in mind this is also true for shared pillow covers—whether in the bedroom or in common spaces.
Watch Out for Pink Eye
“Some evidence suggests conjunctivitis, which most of us know as pink eye, could be a symptom of COVID-19,” report the experts at All About Vision. “However, this is said to be rare, with pink eye developing in an estimated 1% to 3% of people with coronavirus.” Alternately, you may have regular old pink eye—and rub your eye, thus transmitting the coronavirus.
The Rx: If you have conjunctivitis, call your medical professional to discuss.
So What Can You Do?
“Lack of proper eye protection was associated with an increased risk of SARS transmission,” says one study in All About Vision. “Therefore, the eyes are suspected as a route for spreading the SARS virus and, possibly, COVID-19.” They recommend you:
- “Wash your hands frequently and thoroughly with soap and water. If you don’t have access to soap or water, clean your hands with an alcohol-based sanitizer.
- Resist the urge to touch your eyes, nose and mouth.
- Stay away from people who’ve been exposed to or contracted the coronavirus.
- Cover your mouth and nose with a tissue when you cough or sneeze, or use the inside of your elbow. Throw tissues in the trash immediately after using them.”
