• eye width adjusting picture displaying image data storage locations for storing image data for displaying the eye width adjusting picture;
• and
• a processor for executing the program stored in said eye width adjusting picture displaying program storage locations and for accessing image data stored in said eye width adjusting picture displaying image data storage locations to cause said left and right display units to display said eye width adjusting picture,
• wherein the space between said left and right display units may be adjusted by operating said width adjusting mechanism on the basis of a visually recognized state of the eye width adjusting picture displayed in said left and right display units, wherein
• said eye width adjusting picture displayed in said left display unit includes a first figure having its displayed area at least in the vicinity of the left end in the picture and a second figure having its display area at least in the vicinity of the right end in the picture,
• said eye width adjusting picture displayed in said right display unit includes a third figure having its display area at least in the vicinity of the left end in the picture and a fourth figure having its display area at least in the vicinity of the right end in the picture,
• said first and third figures being disposed in positions where they do not overlap each other,
• said second and fourth figures being disposed in positions where thy do not overlap each other,
• wherein the space between said left and right display units may be adjusted by operating said eye width adjusting mechanism so that all of said first through fourth figures are visible when the eye width adjusting picture displayed in said left and right display units is seen through both eyes.
