Purpose of Early Sunglasses Was Not to Block Sunlight
The Inuit invented the first sunglasses from walrus ivory, while modern UV-protective and fashionable sunglasses evolved over centuries, with key developments in Rome and 18th-century Europe.
Inuit Sunglasses: The Pioneers
It might come as a surprise, but the Inuit people are credited with inventing the earliest form of sunglasses. These ingenious creations were crafted from flattened walrus ivory. The Inuit would look through narrow slits in these ivory pieces. Unlike modern sunglasses designed to shield eyes from harmful UV rays, these primitive glasses had a different purpose. The slits significantly reduced the amount of light entering the eyes, which was crucial for hunting in environments where sunlight reflected intensely off snow and ice.
Roman Innovations: Polished Gems for Gladiator Games
In a different part of the world, during the 1st century AD, the concept of enhancing vision took a unique turn. Roman Emperor Nero is reputed to have watched gladiator games through polished gems. These gems weren't designed to offer UV protection. Instead, they were likely used to improve the visibility of the action in the arena and possibly to obscure Nero's reactions from those around him. This practice predated the invention of any form of spectacle lenses.
18th-Century Europe: The Advent of Tinted Eyeglasses
Fast-forward to 18th-century Europe, where the concept of eyeglasses began to evolve significantly. During this period, tinted lenses started gaining popularity. Unlike earlier iterations, these glasses aimed to protect the wearer’s eyes from sunlight. Tinted lenses began transitioning towards eyewear that combined functionality with eye protection.
Modern Sunglasses: Technological Advancements and Fashion
With continuous advancements in technology, sunglasses have reached a point where they offer optimal UV protection. Today’s sunglasses are a functional accessory for protecting the eyes from harmful rays and a fashionable statement. They embody a blend of centuries-old innovation and modern technology, providing both style and safety.
