Bacteria live on our eyeballs – and understanding their role could help treat common eye diseases
You may be familiar with the idea that your gut and skin are home to a collection of microbes – fungi, bacteria and viruses – that are vital for keeping you healthy. But did you know that your eyes also host a unique menagerie of microbes? Together, they’re called the eye microbiome. When these microbes are out of balance – too many or too few of certain types – eye diseases may emerge.
With a study showing bacteria live on the surface of the eye and stimulate protective immunity, scientists are beginning to discover the microbial factors that can be exploited to create innovative therapies for a range of eye disorders like Dry Eye Disease, Sjogren’s Syndrome and corneal scarring.…

Now in Sight: Success Against an Infection That Blinds
Quietly, in the shadow of fights against better-known diseases like Ebola, AIDS and malaria, the 20-year battle against trachoma is chalking up impressive victories.
Why you really, really, really shouldn't shower or swim with your contacts in
But don’t get too worried: Acanthamoeba keratitis is rare. In the U.S. there are just one to two cases per 1 million contact users annually. And the best news is that we can avoid it. “But a little bit of concern is good,” Raju says. “Contacts are great as long as we take care of them, but we have to remember it’s still plastic. We don’t need them in our eye 24/7, 365.”
Common eye infections
Not all red eyes are due to infections. Not all eye infections respond to antibiotic eye drops. Conjunctivitis is the most common eye infection. Most cases are viral and do not require antibiotic eye drops. Infectious keratitis is a cause of blindness. It is an emergency that requires specialist treatment.
Eye Infections: What You Need To Know
Eye infections are usually self-limiting, and most resolve with minimal or no treatment. Occasionally, they don’t resolve quickly, and lead to more severe problems that require some type of medication for treatment.
Contact Lens-Related Eye Infections
While contact lenses are safely used by millions of people every day, they do carry a risk of eye infection. The most common infection related to contact lens use is keratitis, an infection of the cornea (the clear, round dome covering the eye's iris and pupil).
Dirty Little Secret: Almost Nobody Cleans Contacts Properly
People who wear contact lenses say they're diligent about keeping them clean. But press them for details, and it turns out that hardly anyone is doing it the right way.
How Contact Lenses Change the Eye's Microbiome
New research finds certain species of bacteria to be more prominent in the eyes of contact-wearers, offering a possible explanation for why they’re prone to some kinds of infections.
New Thinking on Eye Infections and Contacts
Recent outbreaks of serious eye infections among contact-lens users may be tied to a reduced use of chlorine to decontaminate public water supplies in response to a federal environmental mandate, according to a team of Chicago doctors who discovered the latest eye problems.
The Danger of Using Tap Water with Contact Lenses
Pronounced A·can·tha·moe·ba, acanthamoeba is a microbe that is very common in the environment, including in tap water. It has two forms: the trophozoite and the cyst. The infective form is the trophozoite, which can change into a cyst and survive a long time. These trophozoites and cysts can stick to the surface of your contact lenses and then infect your eye.
When eye irritation is more than it seems at first glance
Priya Raja’s eyes were not cooperating. A recent college graduate, she had struggled for months with on-and-off watery, red eyes and sensitivity to light. She found it difficult to look at a computer screen at the medical startup where she worked in Cambridge, Mass., or to focus on the words on a page. Thinking the symptoms might be due to conjunctivitis, a bacterial infection, her primary care doctor prescribed an antibiotic eye ointment. But Raja’s symptoms didn’t improve.

Many common viral eye infections resolve on their own. In cases of severe viral eye infections, an antiviral eye drop may be prescribed. Some viral eye infections require careful administration of steroid eye drops to reduce related inflammation.
C-Health
Many of the viruses, bacteria, parasites, and fungi that can invade the human body are also capable of attacking the surface or interior of the eye.

Symptoms of eye infections may include redness, itching, swelling, discharge, pain, or problems with vision. Treatment depends on the cause of the infection and may include compresses, eye drops, creams or antibiotics.
