AirOptix

I've been using contacts for 6 months. I was prescribed Air Optrix Aqua +1.75 and find them easy to use and good for all day wear and even the occasional overnight. From what I've read (on the net!) in the USA these lenses are rated 6 day, I've gone 3 days without trouble but don't make a habit of it as my optician has not OK'ed such use. I use daysoft 72s as a backup and find them almost as good (no overnight use).

I have been wearing contacts for over 10 years and these are hands down the most comfortable contacts I have ever worn. I've worn Freshlook color contacts and clear, Acuvue Advance and Oasis, and a bunch of other brands, and none compare. I wear the toric version, which are a little bit more expensive. I know it doesn't explicitly say that you can sleep in these lenses, but I have a couple of times and my eyes are just fine the next morning after a few drops of rewetting solution. I love them!

AirOptix is easy to put in and take out, come in 0.25 units in all prescriptions (yay)

Eyes are dryer than previous lenses (proclear compatibles), can't wear for as long (12 hours max), heavier lens and they cause irritation. Really dislike wearing them

AirOptix are made from Silicone Hydrogel that transmits up to 5 times more oxygen than traditional soft lenses as a result there are no problems such as dryness,irritation and redness.
