When light goes through a glass, it get spread out exept for the light 
that goes through the thick base. And even then, given the shape of the 
inside of your glasses, it get's a fair amount of spreading.

In the non-photons version, light goes straight through the glass 
without any deviation.

Do you also use radiosity for that scene?
