The Shiners are a gang of outlaws that have undergone eyeshine surgery and are living in some quarters of Slam City. They call those who have not undergone eyeshine surgery "darkeyes". Riddick battled them in Slam City.
Due to the low number of successful eyeshine operations, they could have either been incredibly lucky, or they may have been a gang of Furyans.
Pitch Black: Slam City Also the Shiners have the ability to see better in the dark than light. Riddick uses this mainly in all of fights or encounters in dark or shady areas.
