Oculus (device)

The oculus was a device used by Supreme Leader Snoke of the First Order. Stationed in Snoke's throne room onboard his Mega-class Star Dreadnought the Supremacy, it functioned as a sophisticated magnifying glass, enabling its user to better see things that were kilometers away. During the First Order-Resistance war, when Rey was brought before Snoke, he forced her to use it to watch the destruction of Resistance transports fleeing the Resistance warship the Raddus for the planet Crait.
