Today I found out what makes your eyes red in flash photographs.  Simply put, that crazy zombie look people tend to get, as if they are about to use you as a pre-lunch snack, has to do with how light from a camera flash reflects off the eye, and the specific wavelengths at which it tends to do this. It is important to note that the term “light” can refer to any electromagnetic radiation, not just the radiation in the visible spectrum. Other factors contributing to the red-eye effect is the amount of melanin in the layers behind the retina, and the age of the person being photographed.  Light skinned people with blue eyes tend to have less melanin in the fundus. Children will also tend to get a red-eye effect more readily then do their adult counterparts.  This is because a child’s pupil will dilate faster than adults, in low light situations. The frequency of electromagnetic radiation that can be seen in the visible spectrum ranges from 400 nanometers (nm) to approx. Due to the Tapetum Lucidum ability to increase the intensity of available light, this tissue layer provides certain animals the ability to see in much dimmer light.  This is obviously quite useful to nocturnal carnivores who hunt at night, or fish at depths  where light is scarce. Hunters have been known to use Eyeshine to locate their prey.  The technique is called “spotlighting”.
In the Movie Blade Runner, the red-eye effect was intentionally induced to indicate which characters were “replicants” or artificial life forms. In a photograph of a child’s face, red-eye in one eye but not the other may be a sign of the cancer Retinoblastoma.
