Abstract
An optical apparatus includes a display that displays an image, and an optical system that includes a filter (a reflective polarizing plate) and a lens (a half mirror surface) arranged on a downstream side and an upstream side, respectively, on an optical axis L of a display and magnifies the image by at least the lens (half mirror surface). The optical apparatus drives the lens along the optical axis L with respect to the filter by a mobile device, or changes the surface shape or the lens power of the lens having a variable surface shape or variable lens power. Thus, the optical path is folded back twice between the filter and the lens of the optical system, and the image is magnified by the lens (the half mirror surface), so that the position of the magnified virtual image can be adjusted according to the diopter of the user.
