This is a pair of open cylinder with an ior of 1.5.
The left one is rotated so that you can see trough both open ends, the other is
seen edge on.
There is also a small spgere with only a pigment of rgbt 1 and no interior at
the center of both cylinders.
As you can see, the ior does affect the background even if you only pass trough
one surface. The sphere is also visible on the right where you see it trough the
side of the cylinder.
On the left, the sphere is completely invisible, but is very visible on the right.
