I was hoping this would generate some discussion .........

Discussion in 'Optometry Archives' started by Alan Robinson, Jul 25, 2003.

  1. I've had one reply to my post .....

    "halos after 0.25D change, repeatable and reversible - any ideas?"

    ....... my optician has told me it must be one of life's mysteries
    ............ I can't believe that there is no explanation!

    I suspect faulty lenses but two in a row from different boxes?

    I don't know where to go next ........ its not like I can take my lens back
    to the opticians, bang my fist on the counter and point at the fault .....

    Any tips gratefully received.

    Maybe because there isn't an easy answer to your situation.

    If you were my patient I would simply duplicate the trial lens pwr
    with your new lenses and see if you still get the halo effect.
    Being overcorrected by just a .25 diopter is no big deal- it shouldn't
    cause any visual comfort problems especially if the halo effect
    was eliminated.

    Also I would have you switch that "halo effect" contact lens to your
    other eye (keeping in mind that the lens is NOT the correct
    pwr for that eye) to see if you noted the halo's in that eye. If you
    did,
    the culprit would likely be the cl itself; if no halo then I would
    suspect
    that the cl is indeed fine.

  3. All good ideas that I would have been happy to try if anyone had suggested
    them ...........:)

    Anyway the good news is that the problem is fixed ..........this morning I
    picked up another set of lenses (third box, identical prescription) and the
    halo has gone. I couldn't believe that two boxes in a row were faulty, but
    that must have been the case.

    The last subtlety is that my new, working lens is packaged as Frequency
    Excel, the lesnes I had problems with were packaged 'own brand' but were
    aparrently made by the same people, but the good lens in my right eye is
    also 'own brand'.

    At least I should have good lenses for three months now!

    Interesting. The first lens in the sixpack of Frequency 55 Torics that I
    tried was blurry all the time, unlike the trial lens which was only
    occasionally blurry. The next one seems to be a bit blurrier than the
    trial lens, but mostly acceptable. Is it possible that QC for these
    lenses really sucks?
    I wore the trial lenses for 3 months, with no apparent detriment. The
    fitter says I can probably wear them for 2 months.
