The invention relates to a lens (5) having an extended focal range, wherein the lens (5) consists of a transparent material and has two optical surfaces (2, 4), wherein the lens (5) has a refractive power distribution F . According to the invention, the refractive power distribution F tot of the lens (5) changes relative to a plane perpendicular to the optical axis (10) as a function of the radial height r and the azimuth angle phi of the aperture between a calculated basic value of the refractive power F lens not equal to zero and a maximum value F spiral max (r, phi). The refractive power distribution thus results computationally as F(r, phi) =F(r) + F(r, phi), with the spiral refractive power component F(r, phi) =F(r)* w(phi), wherein F spiral max(r, phi) is non-linearly radius-dependent and w(phi) is a factor for the refractive power component with a spiral profile. Furthermore, the calculated basic value of the refractive power F lens is divided into a refractive power of a refractive basis System F basis and into a structure-type refractive power F structure, wherein the following holds true: F(r) = F + F. The spiral refractive power component F spiral and the structure-type refractive power component F Structure are added and form a spiral and structure-type additional refractive power F (r, phi) = F + F (r) * w(phi), which is added to the refractive power of the basis System F basis, such that the total refractive power of the lens (5) results as F(r,phi) =F +F(r,phi).
