Abstract
An adjustment method includes rotating a pair of magnifying glasses in directions opposite to each other using γ-rotation, and correcting inclination of an image, caused by the γ-rotation, by rotating the pair of magnifying glasses in directions opposite to each other using the β-rotation, given that rotation about each of axes Xand X, which respectively correspond to visual axes of left and right eyes when an object distance is infinite in a condition of a primary position, is represented by the γ-rotation, and that rotation about each of axis Yand Y, which are respectively perpendicular to the axes Xand Xand are also perpendicular to a z-axis which perpendicularly intersects with the axis Xat a position of a deflector for the left eye and the axis Xat a position of the deflector for the right eye, is represented by the β-rotation.
