Red eyes are mostly prevalent in the photographs that are taken in the night with a flash. The Red color comes from the light that gets reflected from our retinas. In night time, the surroundings are normally dark or dimly lit. And in these conditions, the flash of camera comes as a flood of light for the eyes. The light of the flash occurs so fast that the iris of the eye does not gets enough time to close the pupil. As a result, light is focused onto the retina situated at the back of the eye. Retina is blood rich, because of the blood vessels that nourish the eye. This blood rich retina comes as a Red image, and this is reflected back to the camera. And this results in the Red effect that can be seen in the eyes in the photographs. The more open your pupils are, the more Red effect you get in your photographs.
