Purevision Contact Lenses

Are Bausch and Lomb purevision contact lenses ok for dry eyes?
On the website, it says they have Aergel, which helps keep them moist and comfortable.. And yet many reviewers have complained that they dry out very quickly.. So which is the truth?

Can somebody talk to me about Bausch and Lomb PureVision contact lenses?
I just started wearing the 30 day Bausch and Lomb Purevision contacts. Can you really wear them for night and day? How often are you supposed to take them out and wash them? Thanks for any answers

Purevision contact lenses?
i just got my contacts at my eye doctor which is 4 boxes of Bauszh and Lomb Purevision 6 soft contact lenses. i called in to ask about how long i can wear each pair of contact, the girl on the phone said 2 weeks. But then i checked online for the same contact lenses, everywhere it said this kind of lens have continuous wear for 30 days. can i wear it for 30 days? and why did she say only 2 weeks?
