It's get-out-in-the-sun season: Grab a beach towel, slather on the sunscreen, and order a big drink with a tiny umbrella. But before you get in the water — whether it's a pool, lake or ocean


— grab some goggles.


Don't have a pair? Then you should probably keep those peepers closed when swimming below the surface.

Exposing your eyes underwater to whatever gunk may be lurking there raises your risk for a range of health issues. Some things are relatively benign: For example, if you keep your eyes open


in the pool for too long, they can become red and irritated. But there are more severe effects, too, such as a higher risk for waterborne infections — especially if you wear your contact


lenses underwater (don't!) or have been treated for cataracts.

1. Lakes, rivers and oceans carry risks of infections


"If you swim in water that is not chlorine-treated, like a river or a lake, you're at a greater risk for developing an eye infection,” says Robert C. Layman, an Ohio-based doctor of


optometry and president of the American Optometric Association.


Bacteria can infect an irritated eye, leading to “a serious sight-threatening infection, often called a corneal ulcer,” he adds, which is an open sore on the cornea that can cause severe


pain and lead to blindness if not treated.


One parasite, in particular — called Acanthamoeba, which is found in lakes, rivers, marshes and oceans, but can also be in pools and hot tubs — can wreak havoc on the eyes and cause a rare


but “devastating type of infection,” called Acanthamoeba keratitis, Layman explains.


Catching it early is key since it can be treated with prescription eye medications. However, more severe cases may require a corneal transplant; it can even lead to blindness or require


surgical removal of the eye, Layman adds. People who wear contact lenses are most at risk for this type of infection.

2. Pools have hidden dangers, too


However, pools — even those that are properly disinfected — can also present hazards for open eyes. The chemicals themselves — chlorine, bromine — can cause irritation and redness, plus they


don't get rid of every single contaminant.


"Keep in mind that people in pools rub their eyes more and that can cause corneal abrasions, which can lead to infections,” Layman adds.


It's just like anything else you should probably avoid: The more you expose yourself to it — in this case, waterborne chemicals and contaminants — the worse you feel.
