IOR is 1.3, but the objects are a thin shell, so the effect is reduced vs. a
solid object.  Also, I used "collect off" for the objects, since I read in
the documetation that this is suggested for glass.  The biggest effect is
the change in the shadows (darker due to refracted light) and the caustics
visible on the floor.  I'm still learning how/when to use photons, and
turning them off changed the render from 5.5 hrs down to 1.5 hrs so I'm not
sure if it's worth it for this scene.

Attachment is same render without photons.
