Single-vision soft lenses with aspheric lens design?

    I have a question for all you contact lens experts. I have been using
    the Acuvue 2 lenses in (OD +1.50, OS +2.00). I have 0.5D astigmatism
    in my left eye only. Due to a small amount of blur in my left eye, my
    eye doc gave me Cooper Frequency 55 Aspheric in those same powers.
    With the Cooper lens, my vision in the left eye is noticeably better,
    but the lenses seem to be less comfortable than the Acuvue 2.

    What other single-vision soft lenses are available with an aspheric
    design? I see the Ciba Choice A.B. is aspheric design, and someone
    posted here that other Ciba lenses (Focus Dailies, Focus Night&Day)
    are aspheric designs as well. Ciba dos not advertize this fact, and
    there is no mention of this on the Ciba web site (maybe they want to
    sell more Choice A.B. lenses?).

    Update: Ciba has confirmed that the Focus Dailies, Focus Night&Day,
    are aspherics designs as well as the Choice A.B. lens. My eyecare
    professional would only get me a trial pair of one of those (I asked
    for both the Dailies and Choice A.B.), so I chose the Choice A.B.
    lens. I will get the Dailies lenses to try by "another means". ;)

    As long as it fits my prescription and my eyes, shouldn't an eyecare
    professional allow me to try a few lenses and let me choose which one
    I want to use? Don't the lens makers provide these trial lenses for
    free? Doesn't my eyecare professional know that if they don't get me
    the trials I want, I'm going to go to another eye doc to get them, and
    they will lose a client?

    Since nobody has posted to this I'll post an update. I found the Ciba
    Focus Dailies to be uncomfortable after a couple of hours. I think
    they are drying out. They are fine when I first out them in. Same
    problem for the Ciba Choice AB lens. BTW, I do not have this problem
    with the Acuvue 2, which is not known to be particularly resistant to
    drying out. What's up with that??? I do not have a dry eye problem.
    When I asked my eye doc for a trial pair of the Focus N&D, they first
    said no, that I had already had three trial lenses and they were
    limited in their "trial lens banks" with the lens manufacturers. So,
    then I offered to pay for the lenses and they said "well, we're not in
    the business of selling trial lenses, so we'll get them for you".

    Incidently, they have not checked the fit of any of these lenses since
    the first trial of Acuvue 2 (which I have been using for about 4 years
    now). They also did not examine my eyes with ANY of the lenses in. So,
    why do all of the other lenses seem to be drying out, or could I have
    a fit problem? I should mention that when I was bicycling with the
    Choice AB (with sunglasses on), when I would turn my head I thought I
    could feel the lens move and then I felt some serious discomfort for a
    few seconds afterward. Is the lens moving, or is the wind catching it
    and lifting it up? Again, I never have this problem with the Acuvue 2
    lens.

    Anybody?

    MT,

    That's interesting. I'm using the 8.7 in the Acuvue2 (4+ years), and
    my eye doc always gives me the higher base curve (i.e. 8.6, 8.7) in
    the lenses that have more then one base curve. FWIW, I have not tried
    an 8.3 in any lens. Of course, my eye doc doesn't check my eyes with
    any of the lenses in, so who knows?

    You are joking, aren't you? Do some docs actually do that? And charge
    money for it?
