Title:
低輻輳眼鏡
Document Type and Number:
Japanese Patent JP7387793
Kind Code:
B2
Abstract:
A convergence-reducing lens of a low-convergence spectacle is characterized by a central normal of the convergence-reducing lens that defines a z-axis, and a center of the convergence-reducing lens defines a tangential centered x-y plane, together defining an x-y-z coordinate system, the convergence-reducing lens comprising a distance-vision region, having a non-negative distance-vision optical power, configured to refract a light ray, directed parallel to the z-axis at a distance-vision region point at an x-distance from a y-z plane of the coordinate system, to intersect the y-z-plane at a distance-vision intersection z-distance; and a near-vision region, having a near-vision optical power that matches the distance-vision optical power within 0.5 D, configured to refract a light ray, directed parallel to the z-axis at a near-vision region point at the x-distance of the distance-vision region point, to intersect, the y-z-plane at a near-vision intersection z-distance that is greater than the distance-vision intersection z- distance.
