I have had the Focus Night & Day (30 day ones) for about 6 months now. I love them! Before that I wore Acuvue 2 disposables. These are much more comfortable than the Acuvues. But...I don't wear them for 30 days. I wear them for a week, take them out and disinfect them overnight, then wear them for a week again, and so on. After I have worn one pair for 4 weeks, I throw them away and start using a new pair.
The Focus Night & Day are 76% water, while my old Acuvues had only 58% water. I can definitely feel the difference!
