To fully enjoy the underwater world, swimmers must first ensure their eyes are guarded against the potential irritants below the surface. It is important to be aware of the potential impact on your eye health when swimming in different types of water environments. Both chlorinated pools and natural saltwater bodies can present unique challenges to maintaining healthy eyes.
Chlorine's Effect on Eyes: More Than Just Irritation
Chlorine is widely recognized as a powerful disinfectant in swimming pools, playing a crucial role in eradicating harmful bacteria to ensure a safe environment for swimmers. Despite its effectiveness, chlorine usage is not without its drawbacks. It has the potential to disrupt the protective natural tear film of our eyes, leading to discomfort and a range of eye health issues. Swimmers frequently report eye irritation after spending extended periods in chlorinated water.
In addition to chlorine, swimming pools often contain disinfection byproducts (DBPs), which are chemicals formed when chlorine reacts with organic matter present in the water — substances like sweat, oils, and urine that are introduced into the pool by swimmers. The interaction between chlorine and these organic compounds results in the formation of DBPs. Among these, Trihalomethanes (THMs) and Haloacetic Acids (HAAs) are two prevalent types.
Even though the concentrations are low, the presence of these chemicals in swimming pools can exacerbate the damage to the natural tear film of the eye. Swimming pools follow established guidelines and procedures to maintain all chemicals at safe levels, allowing swimmers to enjoy the water without worry.
Eye Conditions Triggered by Chlorinated Water:
- Chemical Conjunctivitis: Often referred to as "swimmer's eye", is a form of irritation that affects the conjunctiva, the delicate membrane covering the eye. This condition is typically induced by the presence of chlorine in swimming pools, which can disrupt the natural tear film that shields the eye, leading to symptoms such as redness, itchiness, and excessive tearing.
- Dry Eye Syndrome: The chlorine in pool water can cause the eyes to dry out, leading to a gritty feeling and discomfort.
- Acanthamoeba Keratitis: While contact lenses can temporarily correct vision, they are not suitable for swimming. Contacts can absorb water, trapping bacteria against the eye, which increases the risk of infections such as Acanthamoeba keratitis — a serious infection that can occur in swimmers who wear contact lenses, caused by amoebas present in chlorinated water that can survive due to improper pool maintenance. We have previously wrote an article on the dangers of swimming with contact lenses here.
Saltwater's Impact: Natural Doesn't Mean Harmless
Swimming in the ocean exposes your eyes to saltwater, which, while natural, can be harsh on the eyes. The high salt concentration can dehydrate the eyes, leading to symptoms that can affect your swimming experience.
Eye Conditions Associated with Saltwater Exposure:
- Dry Eye Syndrome: Similar to the effects of chlorine, the salt in ocean water can cause significant tear evaporation, resulting in dry, irritated eyes.
- Corneal Abrasions: Tiny salt crystals can act like abrasive particles, scratching the cornea and potentially leading to painful abrasions.
Navigating Waters with Myopia: The Case for Prescription Swimming Goggles
For swimmers with myopia, clear vision underwater is crucial for both safety and performance. Prescription swimming goggles are specially designed to provide clear vision while offering protection from waterborne irritants found in both chlorinated pools and saltwater environments.
Advantages of Prescription Swimming Goggles:
- Visual Clarity: They correct refractive errors, allowing swimmers with myopia to see clearly underwater.
- Eye Protection: Goggles shield the eyes from chlorine, salt, and other irritants that can cause discomfort or infections.
- UV Protection: When swimming outdoors, they protect the eyes from the sun's harmful UV rays.
Proactive Tips for Eye Safety While Swimming
To ensure your eyes remain healthy during swimming activities, consider these precautions:
- Invest in Prescription Swimming Goggles: They offer the dual benefits of clear vision and eye protection. Consider the Agily AV1 goggles that offer excellent visual clarity and UV protection, suitable for both indoors and outdoors.
- Rinse with Fresh Water: After swimming, rinse your eyes to remove any residual chlorine or salt.
- Use Lubricating Eye Drops: Applying eye drops before and after swimming can help maintain a healthy tear film.
Conclusion
Understanding the effects of chlorinated and saltwater on your eyes is vital for swimmers. By taking the necessary precautions, such as using prescription swimming goggles, you can enjoy the benefits of swimming without compromising your eye health.
