Yes, swimming can cause dry eyes for some individuals.
The primary culprit is the chlorine and other chemicals used to disinfect pool water. These chemicals, while essential for maintaining hygiene and preventing the spread of bacteria, can disrupt the natural tear film that keeps your eyes lubricated. Here's how:
-
Tear Film Disruption: The tear film consists of three layers: a mucous layer, a watery layer, and an oily layer. Chlorine can wash away the oily layer, which normally prevents the watery layer from evaporating too quickly.
-
Reduced Tear Production: Frequent exposure to chlorinated water may also lead to decreased tear production in some individuals, exacerbating dryness.
-
Inflammation: Chlorine can irritate the conjunctiva (the clear membrane covering the white part of the eye) and the cornea (the clear front surface of the eye), leading to inflammation and discomfort, which can contribute to dry eye symptoms.
Who is most at risk?
- Frequent swimmers: Individuals who swim regularly, such as competitive swimmers or those who swim for exercise several times a week, are at a higher risk.
- Contact lens wearers: Wearing contact lenses while swimming can increase the risk of dry eyes and eye infections. The lenses can absorb chemicals and bacteria from the water, irritating the eyes and making them more susceptible to dryness.
- People with pre-existing dry eye: Those already suffering from dry eye syndrome may find that swimming aggravates their condition.
How to mitigate dry eyes from swimming:
- Wear swimming goggles: Properly fitted swimming goggles create a seal around your eyes, preventing direct contact with chlorinated water.
- Use lubricating eye drops: Before and after swimming, use artificial tears to help replenish the tear film and keep your eyes hydrated. Choose preservative-free drops to minimize irritation.
- Rinse your eyes: After swimming, rinse your eyes thoroughly with fresh water to remove any residual chlorine.
- Remove contact lenses: Avoid wearing contact lenses while swimming if possible. If you must wear them, use daily disposable lenses and discard them immediately after swimming.
- Stay hydrated: Drinking plenty of water helps keep your body hydrated, which can also benefit your tear production.
While swimming can contribute to dry eyes, taking preventive measures can significantly reduce the risk and keep your eyes comfortable.
