Embodiment 1
[0071] ADD75 widescreen intelligent presbyopia lens free-form surface design
[0072] see figure 2 and image 3 , a wide-screen intelligent presbyopic lens, comprising a front surface 1 and a rear surface 2, both of the front surface and the rear surface are free-form surfaces, and the free-form surfaces include a far-sighted area, a near-sighted area, and a The gradient zone between the near and near zones.
[0073] The curved surface of the viewing distance zone is a polynomial surface, and the shape of the curved surface of the viewing distance zone is determined by the following function:
[0074]
[0075] In the formula, Zsy is the sagittal height at a certain point (X, Y) on the aspherical refraction surface in the far-sighted zone;
[0076] Csy is the curvature at the center of the apex of the aspheric refractive surface in the far-sighted zone, and ,
[0077] ;
[0078] Dsy is the diopter of the far zone;
[0079] n is the refractive index of the mat...
