Why isn't Wavefront technology used to make the perfect perscription lenses?

    Maybe I am missing something here in my reasearch on Lasik/Wavefront.
    Why isn't this technology used to create the perfect perscription
    lens? I for one have never had a perfect perscription. Forget Lasik,
    I can't even get glasses or contacts that work "really" well. If I
    could, I would be a much happier person. Is the reason it's not used
    for regular glasses and contacts because of the cost. One would think
    this "great" dignostic tool would be used for regular perscription
    work as opposed to just lasik. Are Lasik procedures the only way to
    recoup the cost of buying the tool?

    If your eye moves with respect to the lens, as in spectacles, wavefront
    just wont help.

    The technology is in its infancy. Wavefront spectacle and contact lenses
    can and have been produced. As has been said, many aberrations are highly
    position sensitive, dependent upon having the correction lined-up

  4. In use, you look through a prescription lens with a varying line of sight.
    If you were to correct for looking straight ahead, the correction wavefront
    may give good on-axis correction. The lens will not be correct if you swivel
    your eyes, rather than your head, to look off the axis of the lens.

    It may be possible to design a multielement lens to give improved
    performance over a range of directions. But then, you would probably
    complain about the cost and weight of the resultant lens.

    So am I right in inferring that it will never be appropriate for
    glasses but maybe for contacts (since contacs move with your eyes).
    Or am I being too simplistic? I guess contacts move some too. Maybe
    if you superglued them onto your eyeball :)

    While I'm not entirely sure how what they're doing will address the
    issues that have been raised so far in this thread, check out:

  7. I'm not a doctor, but you might be trying the wrong type of eyeglass
    lenses. Many people have difficulty with polycarbonate and other
    types of lenses because they're not very good optically. fyi
