The New Focus Dailies: changes in lens thickness?

    As a followup to my question last week about 'visitint' and
    'aquarelease' in new Focus Daily lenses, the new lens seems to be
    thicker and more rigid than the old one. Can anyone verify whether or
    not lens geometry changed, along with the addition of PVA and a blue
    tint? Is there documentation of such changes?

    I was informed by a representative of Ciba that nothing structurally or
    chemically had changed apart from the addition of PVA.
