A head-mounted device may include optical assemblies for presenting images to a user. Optical assembly positioning systems may be used to adjust the spacing between the optical assemblies to accommodate different interpupillary distances. The optical assembly positioning systems may have motors, shafts rotated by the motors, nuts that receive the shafts and that are moved as the shafts are rotated, and clutches that couple the nuts to the optical assemblies. The clutches may be spring-loaded clutches, magnetic clutches, electrically adjustable clutches, clutches that exhibit fixed clutch holding forces as a function of optical assembly position, and clutches that exhibit varying clutch holding forces as a function of optical assembly position. Electrically adjustable brakes may be used to help secure the optical assemblies in place.
