I have always had problems with dry eyes of lenses, and the problem I do not see the smoke of these lenses. Can easily wear them all day without any irritation or problems, even when I sit and stare into a screen.
But there are a variety minus with Acuvue Moist, and it is its high failrate. If I buy a 90-pack, I expect to throw 10-15 lenses. Right out of the box (I always wash your hands and then rinse your fingers before I take up the lens itself from the plastic packaging) so they can be completely unusable. I have no explanation why, but it is not due to debris on the fingers or eye problems, because the next lens can sit how nicely anywhere. I have been involved in a half carton had similar problems. Does not matter if I change the eye, the lens rubbing and sometimes directly hurt.
The lenses also have the ability to fold in half and then is practically impossible to get up unscathed, because they are so thin and flimsy. Then it's just throwing a whole new lens and take up a new one.
In other words, this is an extremely expensive lens. The rating is therefore a middle ground. When it works, the lens is without a doubt the best I've ever used, but having to discard as many lenses per box is very economical, and it makes the price per lens rises sharply (on an already expensive lens).
