Multifocal Contacts: RGP Vs. Soft...?

    I have tried soft multifocals (ProClear and Purevision), and didn't
    care for the compromise in vision--the simultaneous vision worked
    okay, but it was definitely a compromise. I think one of the problems
    may have been too that neither of these multifocals corrected for my
    astigmatism (I have around 1 diopter correction for both sphere and
    cylinder per eye).

    I am wondering if RGP multifocals (particularly the new Synergeyes
    with dual near center) would be any better? Particularly if they have
    cylinder correction for my astigmatism...?

    It seems to me that simultaneous vision is going to be simultaneous
    vision to the brain, regardless of the material of the lenses, but you
    hear how much better GP designs and materials are at multifocals...?

    Ask for the Proclear Multifocal with astigmatism correction.
    Never the less, still a compromise and still a simultaneously working
    Most RGP lenses are correcting a small amount off astigmatism, it
    depends on the relation between the amount of astigmatism due to
    differences in curvature in two directions of the cornea and the amount
    of astigmatism in refraction error.

    BTW, not all bi/multi focal RGP's are designed as simultaneous viewing
    Ask your professional.
    There are other designs instead of the simultaneously, troubling the
    brains less sometimes.

    Hope this helps,

    Jan or anyone,

    Can you steer me to where the optics of these lenses (equations) are
