The Lamb shift is calculated, in an approximate way, considering the hydrogen atom as an isolated physical system; the quantized radiation field does not play any role in the present approach. Our formalism is based on the generalization of the Dirac wave equation that incorporates the effects of the electron self-fields directly into it. Both the physical picture as well as the mathematical formalism have their roots in the classical theory of the electron.
