Abstract: Progressive multifocal ophthalmic lens having a power addition prescription and presenting a complex surface having a fitting cross and a principal meridian of progression. The lens has, when being worn, a normalized reduced root mean square deviation of less than 0.025 microns per dioptre over a zone that includes the far vision control point and covering a sector whose apex lies 4° below the fitting cross with an angular aperture of between 150° and 160°; and a progression length of 25° or less, the progression length being defined as the angle of lowered of the view direction from the fitting cross down to the point on the meridian for which the wearer's optical power reaches 85% of the addition prescription. The lens is suitable for increased far vision with good accessibility to near vision.

Abstract: The progressive multifocal ophthalmic lens with a complex surface including a prism reference point, a cross mounting unit located at 8[deg] above the reference point, and an umbilicated progression meridian with a power addition value of >=1.5 diopter. The power addition value lies between the reference point of far and near vision. Radius of curvature of the lens is adjusted for the far vision using a reduced root mean square deviation with the power addition lower than 0.65 mu m by diopter. The progressive multifocal ophthalmic lens with a complex surface including a prism reference point, a cross mounting unit located at 8[deg] above the reference point, and an umbilicated progression meridian with a power addition value of >=1.5 diopter. The power addition value lies between the reference point of far and near vision. Radius of curvature of the lens is adjusted for the far vision using a reduced root mean square deviation with the power addition lower than 0.65 mu m by diopter, a zone bounded by a centered circle on the prism reference point and by a diameter of the circle corresponding to sweep angle of 80[deg], a progression length is =25[deg], and a difference in reduced root mean square deviation is lower than 0.12 mu m by diopter. The reduced root mean square deviation is determined by calculating the nullified coefficient of orders of 1 and 2 correspond to defocalization in Zernike polynomial decomposition of a wave front face passes through the lens. The progression length is defined as lower common angle of the cross mounting unit up to the point of the meridian for which an optical power carrier reaches 85% of the power addition value. The difference in the reduced root mean square deviation is calculated by an absolute value. The zone comprises a control point of far vision in which the zone is bounded by the half centered circle on the cross mounting unit and by radius of the circle corresponds to an elevation of 25[deg]. The difference in the reduced root mean square deviation between two symmetrical points in half circle is =0.12 mu m by diopter below a horizontal line located at 8[deg] above the cross mounting unit. The half circle has a horizontal base that passes through the cross mounting unit. The symmetrical axis of the half circle is scattered with the progression meridian. Independent claims are included for: (1) a visual equipment; (2) a long-sighted vision correction process; and (3) a lens assembling process.
