According to an embodiment, an electrically switchable mirror includes: a first electrically switchable layer of cholesteric liquid crystal material, the first electrically switchable layer having a first state in which right-handed circularly polarized light incident thereon is reflected and left-handed circularly polarized light incident thereon is transmitted and a second state wherein right-handed and left-handed circularly polarized light incident thereon are transmitted; a second electrically switchable layer of cholesteric liquid crystal material, the second electrically switchable layer having a first state in which left-handed circularly polarized light incident thereon is reflected and right-handed circularly polarized light incident thereon is transmitted and a second state wherein right-handed and left-handed circularly polarized light incident thereon are transmitted; and a first electrically switchable wave plate disposed between the first and second electrically switchable layers.

An optical viewing apparatus may include an objective lens assembly and an one eye piece assembly connected to the objective lens assembly. The optical viewing apparatus may exhibit a field of view in the range of between 40&#xb0; and, preferably beyond 80&#xb0;, and an eye-relief of at least 15 mm, and the optical viewing apparatus may exhibit a foveated image for at least one field of view (FOV) wherein the optical on-axis resolution decays toward the periphery of the field of view.
