Medical Forum / General / Vision / May 2006Focus Dailies: 2 questions
My latest prescription was filled with tinted lenses, a first for me. Question 1: Are un-tinted (i.e., without 'visitint') Focus Dailies still made, and are they available in the U.S.? Question 2: Do all Focus Dailies exclusively come with "AquaRelease"? The box has the words "All Day Comfort" printed on it, but nowhere does it say "AquaRelease". FWIW, the lenses are sphere, i.e., neither torics, nor progressives. Thanks in advance. -ds > My latest prescription was filled with tinted lenses, a first for me. > > Question 1: Are un-tinted (i.e., without 'visitint') Focus Dailies > still made, and are they available in the U.S.? Focus Dailies were reformulated recently, adding visitint. Most people would rather have a handling tint and the lack of one in the old dailies was a source of complaints. If you want clear ones you will need to find old stock. > Question 2: Do all Focus Dailies exclusively come with "AquaRelease"? > The box has the words "All Day Comfort" printed on it, but nowhere > does it say "AquaRelease".

Is it a change to lens material, structure or geometry, or is it an additive to the solution in which the lenses are stored? Or both?
