Definition:
Sunglasses are protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are colored, polarized, or darkened.
Etymology:
Sun comes from Old English “sunne,” meaning the sun, which itself derives from the Proto-Germanic “sunnōn” and the Proto-Indo-European “sóh₂wl̥,” both meaning sun. Glasses comes from the Old English “glæs,” meaning glass or a transparent substance, which is from the Proto-Germanic “glasam” and the Proto-Indo-European “gʰel-” meaning to shine or be bright.
The earliest use of sunglasses as a term dates back to the early 20th century.
Symbolism:
Sunglasses are a symbol for filtering light, which symbolically means to filter illusions. For example:
In the film series “The Matrix,” the Matrix is a simulated reality created by intelligent machines to subdue the human population while their bodies’ energy is harvested. The majority of humanity is unaware that they are living in a simulation, believing the artificial reality to be their actual world. In the film series, sunglasses play a significant symbolic role, as they help characters distinguish between the Matrix and reality. Sunglasses are worn by many of the main characters, including Neo, Morpheus, Trinity, and Agent Smith.
The movie “They Live” follows the protagonist John Nada, a drifter who discovers a pair of sunglasses that reveal a hidden reality. When Nada puts on the sunglasses, he sees that the world is controlled by alien creatures who use subliminal messages to manipulate humanity.
