Abstract
An ophthalmological optical element, in particular a spectacle lens, includes a first refractive optical substrate, which has a positive or negative first optical power; a first diffractive optical element, which has a second optical power; and a second diffractive optical element, which has a third optical power. The first diffractive optical element and the second diffractive optical element have opposite optical powers. The first diffractive optical element and the second diffractive optical element interact in an at least partly achromatic manner.
