    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.

    Thanks for the info!

    What exactly is 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? Or neither?

    The lens now contains about 1% polyvinyl alcohol (PVA), which slowly
    leaches out of the lens and acts as a lubricant. The actual lens itself
    is, and always has been based on a cross-linked form of PVA
