broke the rule in the second one -- went to a 1.15 total Your refraction number for the lens is wrong. You are using a number for the base material without shape distortion. You need to adjust the actual refraction number of the material to reflect the warping produced by the lens shape (perhaps the cosine of the prescription?) instead of altering the the Poser_surface setting for the reflection.
