<p>A portable viewing apparatus (11) having a plurality of associated pairs of left and right optical modules (13L and 13R), each pair of which can be selectively used to provide a user with a different viewing effect when viewing objects such as video monitors. Exemplary viewing effects include uniform two-dimensional magnification over a variety of ranges and disanamorphic magnification for wide-screen and three-dimensional viewing of special programming material. The selected pair of optical modules are removably attachable to mounting shoes, and separate control assemblies are configured to allow the user to manually adjust the interocular spacing and convergence/divergence of the selected optical modules.</p> |
