Can you swim with contact lenses?

Optometrists recommend that contact lens wearers follow the “three S rule”: don’t swim, shower or sleep in your lenses.

Why? Because all three can lead to irritation, and in some cases, serious infection. Water can carry all sorts of pathogens and parasites – the most dangerous being acanthamoeba, which attaches to your contact and works its way into the cornea. In very severe cases acanthamoeba infections can cause loss of vision.
