The water looks clear. Your eyes may disagree. A swimming pool, lake, ocean, or hot tub can be refreshing, but opening your eyes underwater exposes them to chemicals, salt, microorganisms, and other substances that do not belong on the eye’s delicate surface. Sometimes the result is temporary redness or irritation. In other cases, an infection or injury can affect the cornea, the clear front surface of the eye.
The good news is that protecting your eyes does not have to take the fun out of swimming. At Kremer Eye Center, we focus on medical and surgical ophthalmology services for patients with specific eye conditions. If swimming is followed by persistent pain, redness, light sensitivity, or vision changes, a medical evaluation can help identify whether the cornea or another part of the eye has been affected.
Water and eyes have a complicated relationship. Your tears help protect and lubricate the surface of the eye, but swimming water introduces a different environment. Pool chemicals can irritate the eye surface, while natural bodies of water may contain microorganisms and other substances. Even treated pools are not completely free of germs, and hot tubs can also expose the eyes to microorganisms.
The cornea deserves particular attention. This clear outer layer helps protect the eye and plays an important role in focusing light. It can become damaged by scratches, environmental irritants, and infections. Corneal problems may cause symptoms such as blurry vision, pain, redness, tearing, glare, or sensitivity to light.
Swimming with contact lenses can create an additional concern because water can carry germs that may become trapped between the lens and the eye. The CDC recommends keeping contact lenses away from water, including while swimming, because water exposure can increase the risk of eye infection. If you wear contact lenses, follow the swimming guidance provided by your community eye care provider.
A pair of swim goggles may be the smallest piece of equipment in your swim bag, but it has an important job. Well-fitting goggles create a barrier between your eyes and the surrounding water, helping reduce direct exposure to chlorine, salt, microorganisms, and debris.
Fit matters. Goggles should form a comfortable seal around the eyes without needing to be tightened excessively. If water repeatedly leaks inside, adjusting the fit or choosing a different style may provide better protection.
Try not to rub your eyes during or immediately after swimming. If the eyes are already irritated, rubbing can worsen discomfort and may cause minor injuries to the surface of the eye. Wash and dry your hands before touching the area around your eyes.
According to the CDC, Acanthamoeba keratitis is a rare but serious infection of the cornea, and exposure risks include swimming or using a hot tub while wearing contact lenses*. This highlights why limiting water exposure to the eyes and recognizing persistent symptoms can be important for protecting corneal health.
Most people do not leave the pool expecting to think about their corneas. Then an eye stays red. Light suddenly feels uncomfortable. Pain does not go away. Vision seems blurry.
Those are moments when the cornea may need closer attention.
The cornea is the transparent outermost layer at the front of the eye. It helps protect the structures inside the eye and helps focus light for clear vision. Because it is directly exposed to the environment, the cornea can be affected by injuries, irritants, and infections.
Our center provides medical and surgical specialty care for corneal diseases and related conditions. Depending on the specific problem, treatment may involve medication or a surgical procedure. The important distinction is between brief irritation and symptoms that persist or worsen.
Opening your eyes underwater can expose them to chlorine, salt, microorganisms, and other substances that may cause irritation. The risk can vary depending on where you are swimming, but wearing well-fitting swim goggles helps create a barrier between your eyes and the water.
Salt water can cause burning, stinging, redness, or temporary discomfort because its salt concentration differs from that of your natural tears. Other substances in ocean water, including sand, debris, and microorganisms, may also irritate the eye surface. Swim goggles can help reduce direct exposure.
Chlorine exposure commonly causes temporary redness, dryness, or irritation after swimming. Occasional exposure is less likely to cause lasting problems, but repeated irritation or persistent symptoms should not be ignored. If eye pain, redness, light sensitivity, or blurry vision continues after swimming, a medical evaluation can help determine whether the cornea or another part of the eye has been affected.
Swimming should leave you thinking about the next lap or the next afternoon by the pool, not wondering why one eye still hurts hours later. If eye pain, redness, or vision changes continue after swimming, Kremer Eye Center can evaluate conditions that may require specialty medical care.
