I have brown bright eyes. Why do i always get red eyes in pictures?

What is happening is that the pupil of a person’s eye, even though it appears to be black when we view it, is actually clear. Since the inside of the eyeball is normally never illuminated, we see it as a small black circle. But in some flash photos, if the flash is close to the lens of the camera, its illumination sends a burst of light right through to the rear of the inside of the subject’s eyeball. The retina of your subject’s eyes is rich in red blood vessels, and this produces the bright red color we see in the pictures.
