Many people look to contact lenses as a way to correct their vision. While contacts may offer convenience and freedom that glasses don’t always provide, there are some added risks that contact lens wearers take on.
Pink eye and contacts are known to go hand in hand. Even the most diligent contact lens care may not be enough to prevent the occasional eye infection. So, what does one do if the lenses they rely on are the cause of their conjunctivitis?
Below, we touch on the different types of conjunctivitis and other eye infections that wearing contact lenses can cause. Plus, how your use of contact lenses is affected during and after dealing with an eye infection.
Eye infections from contacts
An eye infection can happen to anyone. However, contact lens wearers are at a greater risk of contracting pink eye and other eye infections. Here are some eye infections most commonly associated with contact lens use:
Bacterial conjunctivitis
Bacterial conjunctivitis is a strain of pink eye that is typically caused by staphylococcal or streptococcal bacteria. This bacteria can come from respiratory droplets or skin, whether it’s yours or someone else’s.
Practicing poor hygiene, frequently touching your eyes and face, and making physical contact with other people are common ways to contract bacterial conjunctivitis. Bacteria can also be spread through contaminated eye makeup and other items that come into contact with your face, such as towels and pillows.
It’s not wise or safe to share eye makeup or contact lenses (prescription or cosmetic) with another person. This exposes both parties to bacteria and potential infection.
Giant papillary conjunctivitis
Giant papillary conjunctivitis (GPC) is often classified as a form of allergic conjunctivitis, but it is also a type of conjunctivitis caused by irritation of the inside of the eyelids, according to Review of Optometry. Most often, the culprit that causes GPC is irritation from the edge or surface of a contact lens — especially when a dirty lens with protein deposits causes an inflammatory response.
GPC is seen more frequently among people who wear soft contact lenses than among those who wear rigid gas-permeable (RGP) lenses.
Treatment of GPC usually involves switching to a different type of contact lens and more frequent lens replacement, including the use of daily disposable contact lenses. In some cases, the person with giant papillary conjunctivitis will have to discontinue wearing contacts and wear only eyeglasses for a period of time until the GPC clears up. To decrease your risk of GPC returning, it’s wise to reduce your contact lens wearing time and wear your glasses more frequently.
Acanthamoeba keratitis
While this condition is rare, contact lens wearers are almost exclusively at risk. Acanthamoeba keratitis occurs when a parasite (Acanthamoeba) infests the eye.
Acanthamoeba are typically found in water, including swimming pools, hot tubs and tap water. When contact lens wearers use tap water to clean or store their contacts, or when they choose to swim in their contact lenses, they’re exposing their eyes to those water-dwelling parasites.
If not promptly treated, Acanthamoeba keratitis can cause permanent vision loss or require surgery to recover lost eyesight.
Can I wear contacts with pink eye?
Contact wearers are often reluctant to stop contact lens use during an eye infection such as pink eye. After all, how do you know if you have an eye infection from contacts?
Though it may seem tempting, as soon as you notice something is “off” in one or both of your eyes, the first thing you should do is remove your contacts and switch to glasses.
It’s difficult to pinpoint the cause of an eye infection without seeing an eye doctor who can examine your eyes and make a determination. However, even if your contact lenses didn’t cause the eye infection, continuing to wear them certainly won't help.
Contact lenses are like velcro when it comes to bacteria — they collect and store the bacteria entering and currently residing in your eyes. This is counterproductive when trying to clear up an eye infection.
Another issue: Eye infections typically cause a gritty or burning sensation in the eyes that is only made worse by wearing contact lenses.
So, while it may not be convenient or stylish, swapping out your contacts for a pair of specs is the safest, most comfortable choice for your eyes if they are irritated or infected.
