1. An optical device comprising:
a heat source that produces heat while operating;
a thermally conductive optical element that is optically transparent and that dissipates the heat produced by the heat source, wherein the thermally conductive optical element transmits light waves and directly facilitates presentation of visual data to a user; and
a thermally conductive connector that transfers the heat between the heat source and the thermally conductive optical element,
wherein the optical device corresponds to an augmented reality device.
