Pets & Animals Fast Facts, Last Updated:09/06/2010 Cats have excellent diurnal and night-vision. In very bright light, the slit-like iris closes very narrowly over the eye, reducing the amount of light on the sensitive retina, but greatly limiting the cat's field of view. An organ called the tapetum lucidum is responsible for their strong low-light vision, as well as for the varied colours of cats' eyes in flash photographs. As with most predators their eyes are both forward-facing, affording depth perception at the expense of field of view. Cats are weakly trichromatic. Reciprocal Link Exchange by Link Foundry.
