About Solar Eclipse Glasses
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.
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. 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.
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.
A solar eclipse (as seen from the planet Earth) is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and when the Moon fully or partially blocks (“occults”) the Sun. This can happen only at new moon when the Sun and the Moon are in conjunction as seen from Earth in an alignment referred to as syzygy. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured.
If the Moon were in a perfectly circular orbit, a little closer to the Earth, and in the same orbital plane, there would be total solar eclipses every month. However, since the Moon’s orbit is tilted at more than 5 degrees to the Earth’s orbit around the Sun, its shadow usually misses Earth. The Moon’s orbit must cross Earth’s ecliptic plane in order for an eclipse (both solar as well as lunar) to occur. In addition, the Moon’s actual orbit is elliptical, often taking it far enough away from Earth that its apparent size is not large enough to block the Sun entirely. The orbital planes cross each other at a line of nodes resulting in at least two, and up to five, solar eclipses occurring each year; no more than two of which can be total eclipses. However, total solar eclipses are rare at any particular location because totality exists only along a narrow path on the Earth’s surface traced by the Moon’s shadow or umbra.
An eclipse is a natural phenomenon. However, in some ancient and modern cultures, solar eclipses were attributed to supernatural causes or regarded as bad omens. A total solar eclipse can be frightening to people who are unaware of its astronomical explanation, as the Sun seems to disappear during the day and the sky darkens in a matter of minutes.
Since looking directly at the Sun can lead to permanent eye damage or blindness, special eye protection or indirect viewing techniques are used when viewing a solar eclipse. It is technically safe to view only the total phase of a total solar eclipse with the unaided eye and without protection; however, this is a dangerous practice, as most people are not trained to recognize the phases of an eclipse, which can span over two hours while the total phase can only last a maximum of 7.5 minutes for any one location. People referred to as eclipse chasers or umbraphiles will travel to remote locations to observe or witness predicted central solar eclipses.
