Artificial eyes in the wizarding world seem to have unusual powers, as a rule.
- A "staring glass eye" was among the Dark items for sale in Borgin and Burkes during Harry's first visit (CS4).
- "Mad-Eye" Moody's artificial eye is round as a coin and electric blue in colour (GF12). It can see through solid objects, including the back of its user's head (GF13, GF14). It can also see through invisibility cloaks (GF19).
- Magenta Comstock (1895-1991) was an artist who specialized in painting moving eyes in magical portraits. The eyes not only followed an onlooker while in the art gallery, but also back to their homes (JKR, WOM).
