I'm so glad to find out i was not the only one has the problem with Air Optix N&D. I first got a trial pair in April and immediately I felt was not as comfortable as Focus N&D. I had to take out the lens after only a few hours. I then ordered a six month supply of Focus and now its running out. The good news is that Clearlycontact.ca still have Focus N&D in stock. I just ordered one year supply from them. If any of you are looking for the place to order Focus N&D, this might be a choice for you although I think they are more expensive than other places. Oh well, Canadians are always more expensive! Hopefully by next yr of this time, CIBA VISION will fix the problem!
