I checked lens.com for the status of Focus Night and Day, and here's what the notice said: "Ciba Vision has changed the brand name of Focus Night & Day to Air Optix Night & Day Aqua. During the transition period all orders will be shipped as either Focus Night & Day or Air Optix Night & Day Aqua."

It seems clear to me from the postings on this thread that Focus Night & Day and Air Optix Night & Day Aqua are not the same thing. However, I compared the two brands of lenses on Lens.com, and they have the same material (76% lotrafilcon A) Same base curves (8.4 and 8.6) same diameter (13.8) and the same powers (from -10 to +6). Perhaps there's some kind of coating or something that makes the difference. Anybody know?
