How Does Swimming Affect Your Eye Health?
April 27, 2015
Everyone enjoys a dip in a nice, cool pool during the sweltering summer months – especially in Arizona. But what does swimming do to your eye health? Does exposure to chlorine cause permanent damage to your eyes? What are the effects of swimming while wearing contact lenses? Keep reading for answers to these questions and more.
What Chlorine Does to Your Eyes
While there’s no evidence of long-term damage to eye health due to chlorine exposure, there are dangers associated with it. Contrary to popular belief, though, these dangers aren’t simply a result of your eyes coming in contact with the chemical. In actuality, the redness and discomfort that sometimes accompany swimming are caused by bacteria that lingers in the water. This is because, when submerged in chlorine-treated water, your eyes lose the tear film that protects against infection.
Even though the purpose of chlorine in pools is to reduce the amount of harmful bugs, some contaminants are resistant to the chlorine that is used. This means the health of your eyes can be compromised with infections caused by bugs still lingering in the water. The most common infection swimmers experience is pink eye.
Concerns for Contact Lens-Wearers
When you wear contact lenses while swimming, those lenses trap chemically-treated water, meaning your tear film has no chance of repairing itself and your eyes remain exposed to harmful bacteria. If you must swim in your lenses, eye health experts recommend rinsing them immediately after you swim, and avoiding sleeping in them. Failing to do so could lead to a serious eye condition called acanthamoebic keratitis, which has been known to cause blindness in serious cases.
Protecting Your Eye Health This Summer
It’s not all bad news – you don’t have to completely avoid the pool this summer in order to maintain your eye health. Just be smart and take these precautions:
- Wear goggles. Swimming goggles reduce your eyes’ exposure to chlorine, meaning your tear film stays in tact and helps prevent any issues.
- Use eye drops. Use lubricating drops to flush away any remaining chlorine and allow your tear film to get back to its job of protecting your eyes.
- Take care of your contact lenses. As mentioned above, rinsing your contact lenses after swimming is crucial to avoid infection.
