Frankly, It depends on your eyes.
I have Freshlook Lenses that are meant for daily use,
And I have been wearing them for...almost a year now,
And every time that I go into the eyedoctor, they tell me that my eyes are perfect and healthy - except for the whole having to wear contacts in the first place.
BUT, I would not suggest doing this, I'm just one of those weird people with really soggy eyes.
Generally speaking, just take care of your lenses (Instructions will come along when you order) and if you have any questions, or feel any discomfort, talk to your optician.
