Red eyes occur when the flash reflects back to the camera from the blood vessels in the back of the eye. It is most common with blue-eyed subjects and children, but can occur in any situation where the pupils are dilated (the dark circle in the middle of the eye is wide open). It is caused by having the flash too close to the lens. Some cameras attempt to solve the problem by "pre-flashing" the flash to cause a reflexive dilation of the pupil. Sometimes this works; sometimes it doesn't.
Reduce or eliminate it by increasing the surrounding light to cause the pupil to dilate (shrink), by using an off-camera flash, or by eliminating the flash entirely and shooting with a brace or tripod if the light cannot be increased. You can also ask your subjects to look at each other, or at some other point of interest, rather than looking at the camera. (This often results in more natural pictures, anyway.)
The flash can also be deactivated on most digital cameras. Check your handbook. The camera will then compensate for the lack of flash. You can get some nice images that way if you are good at holding the camera steady.
