Just because summer is winding down doesn’t mean you have to give up pool time. Whether you’re taking a refreshing dip on a warm fall day or heading to an indoor pool during the winter, swimming remains an enjoyable way to stay active and have fun. But have you ever stopped to think about what frequent exposure to chlorinated water might be doing to your eyes?

Why Pools Are Chlorinated

Chlorine is added to pool water to keep it clean by controlling the spread of harmful bacteria and viruses. It works effectively as a disinfectant, but its performance depends on several factors, such as how recently it was added, its current concentration, and how heavily the pool is being used.

Chlorine and Your Eyes: What’s the Risk?

When your eyes are submerged in chlorinated water, the natural tear film that usually protects your cornea gets stripped away. Without this protective layer, your eyes are more vulnerable to irritants and microorganisms that chlorine doesn’t fully eliminate. This makes swimmers more likely to develop infections. One common example is conjunctivitis, or pink eye, which can be caused by bacteria or viruses.

Red Eyes and Blurry Vision After Swimming

Another frequent issue is red, itchy eyes. Chlorine exposure can lead to dehydration of the cornea, causing irritation and temporary blurred vision. Though these symptoms typically clear up quickly, they may linger longer as you age. Artificial tears or lubricating drops can help relieve the discomfort by restoring the moisture barrier your eyes need.

Contact Lenses and Swimming Don’t Mix

If you wear contacts, it’s important to take them out before swimming. Contact lenses increase your risk of developing acanthamoebic keratitis — a serious eye infection that occurs when a microscopic amoeba becomes trapped between the lens and the cornea. This condition can result in corneal ulcers or even long-term vision damage. If you accidentally swim while wearing contacts, remove them immediately, rinse them thoroughly with solution, and avoid wearing them overnight afterward.

Protecting Your Eyes in the Pool

Since you can’t be completely certain what’s in the water, the safest way to keep your eyes protected while swimming is by wearing snug-fitting, water-sealed goggles. With the right gear, you can enjoy the pool year-round without putting your eye health at risk.
