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
perfectly.

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:

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
