Abstract: A head-mountable device can provide an optical module that removes particles from an optical pathway and captures the particles so they do not interfere with the user's view of and/or through optical elements. For example, the display element and/or another optical element can be moved in a manner that releases particles on a viewing surface thereof. The optical module can include a particle retention element that securely retains the particles so that they remain outside of the optical pathway. Such particle removal and retention can improve and maintain the quality of a user's visual experience via the optical module.
