1. An optical apparatus that generates a magnified virtual image of an image, the optical apparatus comprising:
a display configured to output an image light for forming an image;
an optical system configured to magnify the image, the optical system including: a first transmissive/reflective surface and a second transmissive/reflective surface that are arranged on an eye point side and a display side, respectively, on an optical axis of the display; and a lens element in which the second transmissive/reflective surface is provided on one surface on the display side, wherein the first transmissive/reflective surface transmits or reflects at least a part of the image light, and the second transmissive/reflective surface is an aspherical curved surface in which a change amount of a curved surface angle continuously increases or decreases according to a distance from a center, and transmits or reflects at least a part of the image light; and
a mobile device configured to relatively move at least the second transmissive/reflective surface along the optical axis with respect to the first transmissive/reflective surface.
