摘要

The invention relates to an ophthalmic lens arrangement (10) comprising a polariser (11) for polarising light in a polarisation axis; at least one lens cell (13) including a switchable light rotator; a lens member (15) having birefringence properties such that incident light encounters a first refractive index n on an ordinary axis or a second refractive index n_e on an extraordinary axis according to the rotation of the incident light; and a sub lens member (17) having a refractive index n; characterized in that: the or each rotator is operable to rotate incident light by 0° or by 90°, and the polariser is arranged such that the polarisation axis coincides with either the ordinary axis or the extraordinary axis of the or each lens member. The invention further relates to an apparatus for and a method for demonstrating a plurality of optical functions.
