An anecdotal word of warning: I wore bi-weekly disposables as well for quite a few years and would repeatedly sleep in them. Never had dry eyes or irritation, however after a few years I developed tiny capillaries growing in my eye (corneal neovascularization), as it turned out they were not getting enough oxygen.
Supposedly if they continue to grow I could lose my eyesight, and they won't actually go away even if I stopped wearing lenses.
Yeah, that's a good point. I've had that mentioned to me, but I get annual checkups, and have been told that they'd show up in the annual checkup if I were having that problem, at which point I could change my habits (it's not an acute condition that crops up in a month or something). Supposedly that complication has also gotten less common in the past 5-10 years as newer lens materials are much more oxygen-permeable than older ones were.
