  We compute the isospin-asymmetry dependence of microscopic optical model
potentials from realistic chiral two- and three-body interactions over a range
of resolution scales $\Lambda \simeq 400-500$\,MeV. We show that at moderate
projectile energies, $E_{\rm inv} = 110 - 200$\,MeV, the real isovector part of
the optical potential changes sign, a phenomenon referred to as isospin
inversion. We also extract the strength and energy dependence of the imaginary
isovector optical potential and find no evidence for an analogous phenomenon
over the range of energies, $E \leq 200$\,MeV, considered in the present work.
Finally, we compute for the first time the leading corrections to the Lane
parametrization for the isospin-asymmetry dependence of the optical potential
and observe an enhanced importance at low scattering energies.
