Death Song Amber Goggles

Death Song Amber Goggles are protective eyewear seen and used in the Dragons: Race to the Edge, Season 4 episode, "Dire Straits".

History
Hiccup constructed several pair of Death Song Amber Goggles at some point prior to the "Dire Straits" episode.

When traders do not show up at Berk for several weeks, the Dragon Riders fly to the Straits of Baldur to investigate. They determine a Submaripper in lurking in the water. Hicccup, Snotlout, and Astrid return to the Straits to hopefully drive off the territorial dragon out to the open see. Hiccup hands out the Death Song Amber Goggles to the others so that they would be able to see while under water. Hiccup realizes that the Submaripper is chained in place, and retreats to come up with another plan.

Physical Appearance
The Death Song Amber Goggles are constructed of a single thin pane of Death Song amber, placed in a metal frame. It has leather straps to affix around the head. The frame covers both eyes and the nose.

Function
The thin amber allows the wearer to see out (albeit orange-tinted) into water, as the wearer does not need to worry about the water coming into contact with the eyes or getting up their nose.
