Patent attributes
The present invention provides an optical device for augmented reality, the optical device including: an optical means for transmitting at least part of visible light therethrough; and a reflective unit disposed on the surface of or in the inside of the optical means, and configured to reflect image light corresponding to an image for augmented reality, output from an image output unit, toward the pupil of an eye of a user; wherein the reflective unit is formed in an asymmetric shape representing a shape other than a point-symmetric shape; and wherein the point-symmetric shape is a shape in which there is a specific point that allows the shape to be always the same for all rotation angles when the reflective unit is rotated around a specific point on the plane of the reflective unit, and the asymmetric shape is a shape that is not the point-symmetric shape.
