Contacts thinner after three weeks of use?

    Do contact lenses become thinner after using them a few weeks? I have
    been wearing a pair of Biomedics 55 for three weeks and they seem
    notably thinner. Is this the typical evolution? Or is it only my own
    appreciation?

    If the lenses becomes thinner with use, does its oxygen transmission
    increase? So is wearing old lenses healthier?

    Thanks a lot :)

    OK, it should be my impression. Or they can be drying...

    Thanks

    as I understand it, Biomedics 55 is a 2-week lens. They shoul be
    replaced after 2 weeks.

    That depends on where you are. It's marketed as a 2-week lens in
    America, but a monthly lens in Europe (I think) and parts of Asia.

    Yes, it's sold as a monthly lens here, in Spain (and the rest of
    Europe).

    I'm no doctor, I have no clue and I'm just guessing. Most people think
    things are thinner because they are more flexible (or to put it another
    way, flimsier). Perhaps with age they've just lost their shape and are
    more flexible?

    You could be right... but I don't know if lenses lose their shape with
    age.

    Thanks!
