Abstract
An assembly for orienting and fixturing an array of contact lenses in a lens-fixturing tray to enable automated picking of the lenses includes an array of tubes to which a first support tray having an array of lens receptacles each having a respective contact lens therein is removably mounted. A lens-fixturing tray having an array of lens receptacles is removably mounted to the other end of the tubes and the assembly is rotated and submerged in a fluid bath whereby the lenses release from the first support tray and float downwardly through a respective tube coming to rest in a centered, concave side-up position in a respective receptacle of the lens-fixturing tray.
