So what exactly causes Red eye in photographs? I know it only happens when it's dark outside, but does it also happen if there's decent lighting?

When a flash fires, our pupils can't constrict fast enough to block out that light. Since we're in a dark scene (where we're using flashes) our pupils are very dilated. That light goes to the back of our eyes (it's red back there because of the blood) and it bounces back and exists our eyes, reflecting the red color.
Why is it that only the camera sees this red? It's kind of like shining a laser at a mirror. This red light reflects straight back, so when the flash and the lens are very close, we get the red-eye effect.

It used to be such a problem for photgraphers, but now it is so easy to correct, that its not a bother anymore, and its great you can fix it on youre iphone and you have apps and other stuff to fix it. It makes life so much easier. However with film you still have to be careful and always make sure the lightning is good.
