1. An optical apparatus for augmented reality with a vision correction function, the optical apparatus comprising:
an image output unit configured to output augmented reality image light, which is image light corresponding to an image for augmented reality;
a reflective unit configured to transfer the augmented reality image light, output from the image output unit, to a pupil of a user's eye by reflecting the augmented reality image light toward the pupil, thereby providing an image for augmented reality to the user; and
an optical means configured such that the reflective unit is disposed therein, and configured to transmit therethrough at least part of real object image light, which is image light output from a real object, toward the pupil of the user's eye;
wherein the optical means includes a first surface through which at least part of the augmented reality image light reflected by the reflective unit and the real object image light is output toward the user's pupil, and a second surface which is opposite to the first surface and onto which the real object image light is incident;
wherein the reflective unit is disposed inside between the first and second surfaces of the optical means;
wherein at least any one of the first and second surfaces of the optical means has a total internal reflection area formed as a flat surface configured to reflect the augmented reality image light, output from the image output unit, by total internal reflection and has a curved area formed as a curved surface; and
wherein the augmented reality image light output from the image output unit is transferred to the reflective unit after being reflected by total internal reflection once on the total internal reflection area formed as a flat surface provided at the at least one of the first and second surfaces of the optical means.
