Chlorine & Your Eyes: Protection Tips

When chlorine gets in your eyes

Spend time in a heavily chlorinated pool and you'll feel it in your eyes soon enough. That burning, itchy sensation? Your eyes are telling you something isn't right. Chlorine does damage your eye health—but understanding how and why is the first step to protecting yourself.

How chlorine affects your eyes

Chlorine attacks proteins and disrupts your tear film—the protective layer that keeps your eyes moist and safe. That tear film is made of water, oils, and mucus. When chlorine strips it away, your eyes become dry, irritated, and vulnerable to infection and inflammation. You might also notice your vision gets blurry. That's corneal swelling from chlorine exposure.

The good news: most discomfort is temporary. After leaving the pool, your eyes gradually recover and restart producing protective moisture. But that doesn't mean repeated chlorine exposure has no effect. The long-term impact is still being researched, and solid evidence is limited.

You're exposed to more chlorine than you think

Even if you rarely swim, your eyes likely encounter small amounts of chlorine regularly—when you wash your face with tap water or take a shower. At these minimal levels, there's no lasting damage. But it's worth knowing you're not completely avoiding it.

Chlorine and children's eyes

Kids love splashing around in pools, and they do it freely and without caution. That means chlorinated water gets into their eyes—a lot. This can trigger chemical conjunctivitis (inflammation of the eye's conjunctiva): red, itchy eyes that may discharge fluid. Symptoms include swollen eyelids and blurred vision. Though chlorine isn't the only culprit—smoke and chemical fumes can cause the same problem.

How to help. If your child has pool-related eye irritation, rinse their eyes with clean water and apply a cold compress for a while. If it looks more serious, see an eye specialist for medication. Prevention is better: make sure they wear properly fitted swimming goggles in the pool.

Adult eyes recover more slowly

As you age, chlorine irritation lasts longer in your eyes and the protective tear film takes longer to restore. This means older adults are especially sensitive to chlorine. After a pool visit, they're likely to experience discomfort and irritation for a longer period. Like children, prevention is the answer: wear good swimming goggles.

Contact lens wearers need extra caution. Chlorine and bacteria that get into your eye can slip behind the lens. Remove your lenses before entering the pool.

Protect your vision while you swim

The simplest defence is a pair of well-fitting swimming goggles. They're inexpensive, effective, and take seconds to put on. If you're serious about protecting your eyes during water sports—or if you've had laser eye surgery like Flow3—goggles aren't optional.

After swimming, rinse your eyes with fresh water. If irritation persists or vision changes, don't wait—see an eye care professional.

Your eyes deserve the same protection as the rest of your body. A small investment in goggles now saves you discomfort—and trouble—later.
