Does anyone have any experience with Extended or Continuous Wear contact lenses?

Extended Wear = Leave em in for a week, night and day
Continuous Wear= Leave em in for a month, night and day

See (har!), I wear glasses most of the time for convenience - I'm far to lazy to put lenses in every morning - but I like to wear contacts when I go out. I used to get 30 pairs every three months, and since I only ever used about 5 pairs a month, I built up a stockpile! A contact lens mountain as it were. I cancelled my order when we moved over to Ireland.

This mountain is now a tiny hillock. I am running out. Looking online, there are some great deals for daily disposables, but the Extended and Continuous Wear ones caught my eye (har again!).

I love the idea of not having to put lenses in every day, but it feels a bit icky having them in constantly for up to a month... I'm sure they wouldn't be able to sell them if they were bad for you, but still...

I'm tempted to order some of the weekly ones, and see how I get on. They are a bit more expensive than the daily ones, but I think the convenience would easily outweigh the small price increase.

Has anyone tried them?
