Optiboarders: Don't post theoretical CL specifications for any given case, even if it is presented as theoretical.

It may not be theoretical, and this is clearly outside the board rules.

Zeno: A polymethylmethacrilate lens is a hard (PMMA) non-gas permeable rigid lens custom made (fitted to the eye upon which it rest) to the shape of the cornea and precription. No brand name (with a few attempts to the contrary) finest lens for the correction of astigmatism (with a few rare exceptions) ever made for correction.

If you don't know what a hard lens is, you don't need to be asking questions like this.
