A method of producing a group of different bi-aspherical type progressive-power lenses, each of which: having a progressive refractive power dividedly allotted to a first refractive surface that is an object side surface and a second refractive surface that is an eyeball side surface; satisfying the following formulae and: DHf 1 + DHn 1 < DVf 1 + DVn 1 DHn 1 < DVn 1 where, DHf1 is a surface refractive power in a horizontal direction at a far vision power measurement position F1 on the first refractive surface; DVf1 is a surface refractive power in a vertical direction at the far vision power measurement position F1 on the first refractive surface; DHn1 is a surface refractive power in the horizontal direction at a near vision power measurement position N1 on the first refractive surface; and DVn1 is a surface refractive power in the vertical direction at the near vision power measurement position N1 on the first refractive surface, cancelling surface astigmatism components at F1 and N1 on the first refractive surface by the second refractive surface; and providing a far vision power (Df) and an addition power that are requirements of prescription values by a combination of the first and second refractive surfaces, characterized in that the group of bi-aspherical type progressive-power lenses covering the range of far vision powers of -1.00 to +1.00 and addition powers of +1.00 to +3.50 is produced using a group of semi-finished lenses and using the same first refractive surface for all lenses produced in said range. having a progressive refractive power dividedly allotted to a first refractive surface that is an object side surface and a second refractive surface that is an eyeball side surface; satisfying the following formulae and: DHf 1 + DHn 1 < DVf 1 + DVn 1 DHn 1 < DVn 1 where, DHf1 is a surface refractive power in a horizontal direction at a far vision power measurement position F1 on the first refractive surface; DVf1 is a surface refractive power in a vertical direction at the far vision power measurement position F1 on the first refractive surface; DHn1 is a surface refractive power in the horizontal direction at a near vision power measurement position N1 on the first refractive surface; and DVn1 is a surface refractive power in the vertical direction at the near vision power measurement position N1 on the first refractive surface, DHf1 is a surface refractive power in a horizontal direction at a far vision power measurement position F1 on the first refractive surface; DVf1 is a surface refractive power in a vertical direction at the far vision power measurement position F1 on the first refractive surface; DHn1 is a surface refractive power in the horizontal direction at a near vision power measurement position N1 on the first refractive surface; and DVn1 is a surface refractive power in the vertical direction at the near vision power measurement position N1 on the first refractive surface, cancelling surface astigmatism components at F1 and N1 on the first refractive surface by the second refractive surface; and providing a far vision power (Df) and an addition power that are requirements of prescription values by a combination of the first and second refractive surfaces,
