A head-mounted device may have a display with pixel arrays that display content for a user. A head-mounted support structure in the device supports the pixel arrays on the head of the user. A left positioner may be used to position a left lens assembly that includes a left lens and a first pixel array. A right positioner may be used to position a right lens assembly that includes a right lens and a second pixel array. Control circuitry may adjust the positions of the left and right lens assemblies using interpupillary distance information. Sensing circuitry such as force sensing circuitry may be used to ensure that the lens assemblies do not apply excessive force on a nose. Force sensors may be included between the lens assemblies and the nose, such as in, on, or adjacent to a nasal flap, or may be coupled to the lens assemblies.
