What is the worst one digital camera that produces red eye?

is canon cams good against it, if so which one is the best?

It’s usually the flash unit that causes red-eye, not the camera. Red-eye is caused when the camera photographs the retinas at the back of the subject’s eyeballs. The retina has many tiny blood vessels, giving the reflected light a red appearance. Better cameras have a red-eye reduction mode, wherein the flash unit fires twice — first, to illuminated the eyes and cause the irises to contract, thus hiding the retina, then a second time to expose the picture. This is true of both digital and film photography. Look for a camera or flash unit that has red-eye reduction as one of its features.
