Abstract

An optical eye-contact element is disclosed that is at least partly translucent, the optical eye-contact element giving rise to a wavefront error of at most about λ/2, preferentially at most about λ/4, highly preferentially at most about λ/10, in a traversing light beam. The optical eye-contact element may be a so-called applanation plate or applanation lens.
