Eclipse glasses

The mechanist wore eclipse glasses during the solar eclipse on the Day of Black Sun.

Eclipse glasses were a form of eyewear invented by the mechanist to allow members of the invasion of the Fire Nation to observe the eclipse safely without damaging their eyes.[1]


Sokka commissioned the mechanist to produce these special glasses so that when the invasion force invaded the Fire Nation on the Day of Black Sun, they could observe the eclipse safely as a means of keeping track of time.[2] The mechanist produced hundreds of these glasses for the members of the invasion force. When the troops were making their way up the slopes of the caldera in the Fire Nation Capital, the mechanist warned them that the eclipse was starting and ordered them to cover their eyes with the eclipse glasses.[1]


The glasses are made of leather and, although they are referred to as glasses, do not actually contain any glass. The slits block the sun's glare while still allowing the user to see. They are reminiscent of eyewear used by some desert or arctic cultures to reduce glare and offer protection from sandstorms or snowstorms. The sandbenders in the Si Wong Desert wore similar eyewear.[3]


  • The glasses are based on similar eyewear created by the Inuit to protect against excess light reflected off snow and ice.
  • The only ones who did not wear the eclipse glasses were Aang, Sokka, and Toph, who were searching for Fire Lord Ozai's underground bunker, which was hidden in a nearby volcano.[1]
  • Real eclipse glasses are used for safely viewing a solar eclipse before and after totality, rather than at totality as they are used in the show.[4]
