Kind Code:
B2
Abstract:
PURPOSE: To easily attach lenses for eyesight correction and correct eyesight by applying the positioning tool to the external surface of a lens part and sticking the lens for eyesight correction on the internal surface of the lens part through the positioning tool.
CONSTITUTION: A sticking type marking seal is used and a spectacle body 1 is put on a face; and the seal type positioning tool B with a circular or polygonal adhesive layer of, for example, 5-10 is put on a finger tip and while this positioning tool is seen across the spectacle body 1, the seal is stuck on the spectacle body 1 at a position where the visual field is impeded most, i.e., on a dashed line w-w. The spectacle body 1 is detached from the face and the reference sheet 10 of the eyesight correcting lens 2 is stuck having its optical center (p) aligned with the center position of the positioning tool B which is already stuck from the lens part 3 on the opposite side where the positioning tool B is stuck, i.e., from inside the lens part 3, so that the lens part can be fitted while the center of a pupil and the optical center (p) are aligned with each other.
