Swimming is an enjoyable and refreshing activity, offering numerous physical and mental benefits. However, if you wear contact lenses, you may find yourself questioning whether it’s safe to swim with them. The idea of exposing your eyes to chlorine or saltwater while wearing contact lenses may seem concerning, and for good reason. In this article, we explore the risks associated with swimming while wearing contact lenses, what precautions you should take, and the alternatives that can make swimming safer for those who rely on corrective lenses.
The Risks of Swimming with Contact Lenses
When you wear contact lenses, they sit directly on the surface of your eye. This positioning makes them vulnerable to foreign particles and bacteria that may be present in the water. Whether you are swimming in a pool, lake, or ocean, the water you come into contact with is not sterile, and this introduces several potential dangers:
- Infection
Water, especially untreated or poorly treated water, harbors bacteria, fungi, and other microorganisms. When these particles come in contact with your lenses, they can get trapped under the lens, leading to eye infections. A common infection caused by swimming with contact lenses is acanthamoeba keratitis, a rare but serious infection of the cornea. This condition is often associated with contact lens wearers who swim without proper protection. - Dryness and Irritation
The water around you can also interfere with the moisture levels in your eyes. Chlorine in swimming pools, in particular, can strip the natural moisture from both the eye and the contact lens, causing dryness, discomfort, and irritation. Saltwater from the ocean may have a similar effect, though it also introduces additional concerns related to salt buildup on the lenses. - Displacement of Lenses
Swimming, especially vigorous swimming, can lead to the displacement of contact lenses. The pressure from diving into the water or quick movements can cause your lenses to shift or even fall out. This not only impedes your vision but can also be difficult to correct in the middle of a swim. - Reduced Oxygen Flow to the Eyes
Contact lenses require a certain amount of oxygen to keep your eyes healthy. When submerged in water, the lenses may become more airtight, reducing the oxygen flow to your corneas. Prolonged lack of oxygen can result in dryness, discomfort, and even long-term eye damage in severe cases.
What You Can Do to Protect Your Eyes While Swimming
If you need to swim and wear contact lenses, there are several steps you can take to reduce the risks associated with the activity. Here are a few important precautions:
- Wear Waterproof Goggles
The best way to protect your eyes while swimming with contact lenses is to wear a pair of snug-fitting, waterproof goggles. These goggles provide a barrier between your eyes and the water, preventing bacteria, chlorine, and saltwater from coming into direct contact with your lenses. They also help keep your lenses in place, reducing the chances of them becoming dislodged. - Consider Daily Disposable Lenses
If you plan on swimming, consider using daily disposable lenses. These lenses are designed to be worn for a single day and then discarded. Using disposable lenses reduces the risk of infection from bacteria and other harmful organisms in the water, as you won’t need to worry about reusing them and introducing contaminants into your eyes. Plus, if a lens falls out or becomes damaged, you can simply replace it with a fresh pair. - Use Contact Lenses Designed for Water Activities
Some contact lenses are specifically designed for water activities. These lenses are made from materials that are more resistant to absorbing water and bacteria. If you swim regularly, consider consulting with your eye care professional about special lenses that might be more suitable for aquatic activities. - Practice Good Hygiene
Good hygiene is essential when wearing contact lenses in any situation. Be sure to wash your hands thoroughly before touching your lenses, especially if you’ve been in the water. This reduces the likelihood of transferring harmful bacteria to your lenses or your eyes.
Alternatives to Swimming with Contact Lenses
If swimming with contact lenses still makes you uneasy or if you prefer to err on the side of caution, there are alternatives that will help you see clearly while enjoying the water:
- Prescription Swimming Goggles
If you wear glasses or need corrective lenses but don’t want to swim with contacts, prescription swimming goggles are an excellent alternative. These goggles come in a variety of prescriptions, allowing you to see clearly underwater without worrying about the safety risks associated with contact lenses. - Laser Eye Surgery
For those looking for a more permanent solution, laser eye surgery such as LASIK can eliminate the need for glasses or contact lenses altogether. While this option requires careful consideration and consultation with an eye specialist, it could provide the freedom to swim, play sports, and engage in other activities without worrying about corrective lenses.
Final Considerations
While swimming with contact lenses is not strictly advised due to the potential risks involved, there are several steps you can take to mitigate those risks and continue enjoying the water. The key is to prioritize eye health, maintain good hygiene, and use appropriate protective gear. If you’re ever uncertain, it’s best to consult with your optometrist, who can guide you toward the best solution for your lifestyle and vision needs. Whether it’s wearing goggles, using daily disposables, or exploring other alternatives, ensuring your eye safety while swimming is essential for long-term vision health.
