Polycarbonate lenses drive me nuts because their Abbe number is too low; everything looks like an old-school 3-D movie (without looking at it through the red/blue 3D glasses) to me when I wear them.
I think there was some specialty lens company that sold a multi-layer achromatic eyeglass lens, but I believe they have since gone out of business, unfortunately.
The best commonly available material for chromatic dispersion is probably CR-39, followed by Trivex, but the index is too low for very high-powered prescriptions.
