    free form tech!!

    Dear Optiboarders,
    I'am reading any kind of information about the so called free-form technology and the possibility to build optical complex surfaces in order to obtain several improvements about the the thicknesses and optical defects of opthalmic lenses.
    But , my real question is :
    Does it needs the final user this kinds of improvements ?
    I read the very interesting articles of Darryl Meister concerning this argument, and it seems that big companies such as Essilor, Zeiss , Hoya look to this new way of the optical techonolgy as the future to warrant to final user to real customize his lenses .
    But , my real second question is :
    how is possible to be sure to build a real customized optical complex surface ( such as a PAL with internal geometry) when this Complex surface is edged and fixed on a non complex frames and this frames are wear from the users in a noo complex head surface?
    The sound of this Free form technology is :
    I want to build a Ferrari car using tires of
    bicycle.

    There is a lot of great possibilities in true free form technology.

    By utilizing a digitally surfaced lens, a great lens design can be made to the highest degree of accuracy compared to conventional technologies. This can mean easier adaption rates for patients, and the ability to optimize designs (insets, corridor length, etc) based upon rx and frame dimensions all the more.

    Currently the technology is focusing on PALs. Though I believe that in the years to come we will see this type of surfacing take off to all types of materials, and a greater complexity of styles in general... free form slab off anyone?

    It really does get one thinking. We have a nation of cookie cutter "opticians" who have the mentality of a roadkill possum. These folks can't tell the difference between night and day, yet are we to expect them to sell and dispense these new technologies with any degree of accuracy. Sure the lens may be the best, most accurate lens for this patient, but the frame is too big, slips down, got twisted in the edger, and is fit too low because the dispenser did not take into consideration the effects of parallax error when taking measurements.

    It will be very interesting to see how all this technology takes hold and grows!

    Of course, having a more precise rendering of a design, can apply a bit of "forgiveness factor" into the lens. While it may not provide the highest level of optimal correction, the fact that it provides a higher level than conventionally processed designs can still mean a higher success rate by eliminating some (not all) of the problems associated with inaccurate measurements and adjustments.

    I have found that the P360 is by far the MOST UNFORGIVING to fit, dispense, and adjust. 80% of those I've sold have been remade (usually into a physio). I'm not impressed.

    I think the Physion 360 uses the front PAL design of the standard Physio with a use of digital surfacing to try to minimize some of the abberations associated with spherical back curves. I don't think it is as individualized as a lens can be.

    We've been selling freeform slabs for about 3 years now.

    Thank U very much for your reply!

    As you know , I'm not an optician .

    So , if I have understand well this kind of surf. tech. is oriented to give the final user its personal opthalmic lenses very customized and correctly installed in frames.
    So , in this case we tends to reduce any kind of effort about the user'eyes to adapt at the new lenses .
    Is this a correct approach for Human sight system physiology, generally speaking ??
    (I mean less adaptation efforts it's equal to increase of the original eye problem!).



    thanks.

    Mauro
