I'm sure this is going to prove a monumentally stupid question, but I still just have to ask it.
As I understand it, when light hits the objective lens of an optic it has not yet been "split," nor will it be until it reaches the prisms inside the optical barrel.
So, assuming that's true and since nothing bad has happened to the light at the objective lens, how does an ED glass objective lens help anything?
