    As I understand it. Extended RGP has thinner lens. I have a great minus
    diopter eyes. Would less extended RGP be more preferable so that the
    unstable center thickness won't cause the lens to flex at my eyes. I
    found out my contacts is more stable when it is thicker. How
    come center thickness is important in increasing minus myopia when
    they can design thinner lens with the corresponding center thickness
    that won't flex. Or could it be because the center thickness value is
    the same in all kinds of lens thickness (normal, extended, super
    extended) in a given brand?
