I assume they trap bacteria to the cornea, and reduce the tear-flow that normally reaches the cornea you get with each blink.

- alatkins 9y agoThat would make sense. In which case the real risk might be from rising the lens and then inserting it. Getting exposed to water when already inserted in the eye (ie. shower or swimming) might be less risky, unless the water somehow penetrates under the lens. Anyway, this is a good PSA.
