There is provided a simulation device for virtually displaying an image to be viewed through a spectacle lens by a wearer of a spectacle lens, including: an imaging camera configured to perform imaging in a visual field of the wearer; a depth sensor configured to acquire a depth image in the same view angle as an imaging result obtained by the imaging camera; a data acquisition unit configured to acquire lens data of the spectacle lens; an image creation unit configured to create a simulation image on which a view of an image to be viewed through the spectacle lens is reflected, by applying image processing to the imaging result obtained by the imaging camera, based on the depth image and the lens data; and an image displayer configured to display and output the simulation image as an image to be viewed through the spectacle lens.
