VISOR

In the 24th century of a parallel universe, a visor was an ocular device which granted "extraordinary abilities". Geordi La Forge wore a visor, but he would have preferred to have normal vision. Nevertheless, during a mission to Cogen V, Geordi's visor provided useful in examining Borg and Cyberman bodies that were recovered from the planet, enabling him to determine the specific degradation patterns of the weapons used and conclude that the Cybermen and Borg were targeting each other.
