Strange eye reflection

A girl I know was playing with a camera, and got this. No, it's not photoshopped. Could someone explain it?

Edit: I wasn't wondering about the red eye, it was the yellow-eye.

But now I see, so the question has been answered.
 
Does she whear contact lenses? That may have nothing to do with it of course.
 
Just the 'red-eye' effect (pupil doesn't contract fast enough in response to the flash, so the red capilliaries at the back of the eye are visible). Also, some of the light from the flash is being reflected almost directly from the left eye into the camera.
 
Red eye would account for the red in one eye. I was thinking about the yellow half moon reflection in the other. Of course I'm not sure which it was that sorgoth thought was odd.
 
Espritch,

As I said the effect in the left eye is due to a reflection of the flash. I suppose it's apparent shape is due to the shape of the eye, and also that of the flash bulb.

If her eye were pointed directly at the camera, this would be a disk. It's a partial reflection from the boundary between the lens and the vitreous humour. This is a lucky shot; the eye is close enough straight on that you see it, but just a teensy bit off so that it's not a disk. The reflection is the color of the light; it's probably yellow because of color correction algorithms or the curve of the film.

One of the cool things about Fellowship of the Ring was that when Gollum appeared, they simulated this effect in one of his eyes (which wouldn't have happened if he had just been illuminated by ambient light, but never mind; it was still cool). I'm not sure if they added it artistically or modeled the eye well enough for it to fall out of ray tracing.
