This thread is partially suggesting a solution to drk's other thread and exploring the capabilities of freeform lenses.
If we can provide a gradual progression of power in a PAL, why not a gradual increase in prism as well? Would this horribly affect the optics of the lens?
So basically I'm proposing a lens that has 0^ at the fitting cross and X^ at the reading area, with a smooth increase from 0 to X. Freeform people? Is this a pipe dream?
