These filters also do not work on the green effect produced in a pet’s eyes.

It is rare to find a digital camera that does not come with a red eye reduction feature. This feature can be turned off or on. It is best left on in all circumstances other than direct sunlight. The red-eye reduction feature works by flashing a short burst of light at your subject before you snap the picture. This burst of light causes the subject’s pupil to close and makes it less likely for the camera’s flash to reflect off the retina. This in turn reduces the chance of red eye .
It also helps to direct the flash of your camera so it does not directly hit your subject’s eyes. Bouncing the flash off a nearby wall or other object will soften its effect and reduce the chances of this unwanted malady. Between bouncing the flash and using your digital camera’s red-eye reduction feature, your little angel, whether human or animal, will have eyes that don’t glow.
The idea is that the light causes the iris of the eye to shut down a little, thereby lessening the chances of a reflection when the final flash goes off , you can see photography-basic-light
