>What's the difference in thickness of these three lens? In general, the higher the Dk/L of the material, the more stable the lens will be at a particular center thickness. Therefore in general, RGPs made out of ES can be made thinner than EO which in turn can be made thinner than the XO. There's more to it than that, but that, in essence answers your question.
