I don't know POV, but I do know that index of refraction (IoR) shouldn't have
any effect on reflections. Perhaps it does, but it shouldn't. You need do
decrease the reflectivity, not the IoR. The IoR controls how much light bends
when it enters a transparent material.
I don't know how to change the reflectivity in POV, but a search for "reflect"
in the file might prove enlightening.
