Pair of spectacle lenses for binocular vision, manufacturing method, supply system and supply program thereof

A manufacturing method for a pair of spectacle lenses for binocular vision, the method comprising:

• when an inner horizontal direction of each of the spectacle lenses is a direction toward the nose of a user who wears the spectacle lenses, and an outer horizontal direction of each of the spectacle lenses is a direction toward an ear of the user,
• a designing step of providing a portion for viewing an object at a finite distance, to each of the pair of spectacle lenses for binocular vision, and forming a shape of a base in prism to the portion such that a line of sight of the user viewing the object through the portion is directed to a direction that is different from a direction from the object;
• and
• a manufacturing step of manufacturing the pair of spectacle lenses for binocular vision based on a result of the designing step.

A supply system of a pair of spectacle lenses for binocular vision, the system comprising:

• when an inner horizontal direction of each of the spectacle lenses is a direction toward the nose of a user who wears the spectacle lenses, and an outer horizontal direction of each of the spectacle lenses is a direction toward an ear of the user,
• a receiving unit configured to receive information on the spectacle lenses;
• a designing unit configured to provide, based on the information on the spectacle lenses, a portion for viewing an object at a finite distance to each of the pair of spectacle lenses for binocular vision, and form a shape of a base in prism to the portion such that a line of sight of the user viewing the object is directed to a direction that is different from a direction from the object;
• and
• a transmitting unit configured to transmit design information that is acquired by the designing unit.

A supply program of a pair of spectacle lenses for binocular vision, to cause a computer to function as:

• when an inner horizontal direction of each of the spectacle lenses is a direction toward the nose of a user who wears the spectacle lenses, and an outer horizontal direction of each of the spectacle lenses is a direction toward an ear of the user,
• a receiving unit configured to receive information on the spectacle lenses;
• a designing unit configured to provide, based on the information on the spectacle lenses, a portion for viewing an object at a finite distance to each of the pair of spectacle lenses for binocular vision, and form a shape of a base in prism in the portion such that a line of sight of the user viewing the object is directed to a direction that is different from a direction from the object;
• and
• a transmitting unit configured to transmit design information that is acquired by the designing unit.
