Catseye
"Cats eye" refers to a variety of gemstones or a medical condition, both named for the resemblance to a cat's eye, but with distinct meanings. The gemstone, also called Lehsunia, is a phenomenon known as chatoyancy, where a band of light appears to move across the stone's surface. In contrast, Cat Eye Syndrome is a genetic disorder characterized by an iris coloboma, creating a slit-like appearance in the eye.
