I don't think that's true at all. I think the issue with contacts (even dailies) is that they can trap pathogens on the surface of the eye and give them a place to breed, allowing an infection to take hold. This could happen within a day while you have your lenses on. I think dailies are somewhat safer, because you're starting each day with a sterile pair. But splashing any non-sterile water onto them is a mistake.

I think that one source of infection is dirty storage pots. That's what NHS Choices says, and they tend to be evidence based (although we can argue about the evidence they use). http://www.nhs.uk/Livewell/Eyehealth/Pages/Contactlenssafety.aspx http://www.nhs.uk/Livewell/Eyehealth/Pages/Contactlenssafety...

  That seems plausible. But I was once told that ideally you shouldn't even take a shower in contacts (Not that I always followed that advice). Maybe I just had an over-cautious optometrist.

    It's definitely the standard advice, I just wonder how much evidence there is to support it. I guess it does make sense that the lens might make it easier for the bacteria to breed.
