Is chlorine water good for eyes?

Prescription Swimming Goggles

Swimming is a beloved activity for many, providing both a great workout and a fun way to cool off. However, one common concern among swimmers is the effect of chlorine on the eyes. Chlorine is widely used in pools to kill harmful bacteria and keep the water clean, but is it good for your eyes? Here’s what you need to know about chlorine and eye health.

Understanding Chlorine and Its Purpose

Chlorine is a powerful disinfectant used in swimming pools to maintain hygiene and prevent the spread of waterborne diseases. By keeping the water free from bacteria and algae, chlorine ensures a safe swimming environment. However, while effective at keeping pools clean, chlorine can have some adverse effects on your eyes.

How Chlorine Affects Your Eyes

  1. Irritation and Redness: Chlorine can strip away the natural tear film that protects your eyes, leading to dryness and irritation. This can result in red, bloodshot eyes after swimming.
  2. Stinging and Discomfort: Direct contact with chlorinated water can cause a stinging sensation, making your eyes feel uncomfortable and watery.
  3. Dryness: Chlorine can disrupt the balance of natural oils and moisture in your eyes, leading to a dry and gritty feeling.
  4. Allergic Reactions: Some individuals may be more sensitive to chlorine and experience allergic reactions, such as itching, swelling, and increased irritation.

Mitigating the Effects of Chlorine on Eyes

While chlorine is not inherently harmful in small doses, prolonged exposure can lead to discomfort and irritation. Here are some tips to protect your eyes while enjoying your time in the pool:

  1. Wear Goggles: The simplest and most effective way to protect your eyes from chlorine is to wear swim goggles. Goggles create a seal around your eyes, preventing direct contact with chlorinated water. Choose goggles with a comfortable fit and an anti-fog coating for the best experience.
  2. Rinse Eyes After Swimming: After your swim, rinse your eyes with fresh water or a saline solution. This helps remove any residual chlorine and soothes irritated eyes.
  3. Use Artificial Tears: If your eyes feel dry after swimming, lubricating eye drops or artificial tears can help restore moisture and alleviate discomfort.
  4. Avoid Rubbing Your Eyes: Rubbing your eyes can exacerbate irritation and redness. Instead, gently dab them with a clean towel.
  5. Shower Before and After Swimming: Taking a shower before entering the pool can reduce the amount of sweat and oils that react with chlorine, while showering after swimming helps remove chlorine from your skin and eyes.

When to See a Doctor

If you experience persistent eye irritation, redness, or pain after swimming, it’s important to consult an eye care professional. They can provide advice tailored to your specific situation and ensure there are no underlying issues.


Chlorine is essential for maintaining clean and safe swimming pools, but it can be harsh on your eyes. While chlorinated water is not good for your eyes, taking precautions like wearing goggles and rinsing your eyes can minimize discomfort and protect your eye health. By following these tips, you can enjoy the benefits of swimming without compromising the comfort and safety of your eyes.
