| titleOfInvention | Aspherical spectacle lens for correcting hereophoria of the eye |
| abstract | An aspherical spectacle lens (1) has a prismatic power to correct hereophoria (visual axes being deviated during resting periods) of an eye. The spectacle lens has front (2) and back (3) surfaces, one of which is a rotationally-asymmetrical aspherical surface for correcting the aberrations caused by adding the prismatic power. When the back surface(3) is rotationally-asymmetrical, curvature of an intersection line (7) of a plane containing the normal (Z2) to the rotationally-asymmetrical surface at a framing reference point (4) and the rotationally-asymmetrical surface (3) at the prism base side may be larger than that at the apex side (i.e. in the area marked "R"). The framing reference point is coincident with a pupil position (5) of a user when the spectacle lens is installed on a frame. On the other hand, when the front surface (Fig 3, 12) is rotationally-asymmetrical, the curvature of the intersection line at the prism base side may be smaller than that at the apex side. |
