While the concept of tinted lenses dates back centuries, the development of lenses specifically for sun protection has evolved over time.
Early Developments in Tinted Lenses
-
12th Century China: The Chinese crafted glasses using smoky quartz lenses. These, while not intended for sun protection as we understand it today, demonstrate an early use of tinted materials in eyewear.
-
James Ayscough (1752): An early optician and inventor, James Ayscough developed blue and green tinted lenses. However, it's important to note that his primary goal was vision correction, not protection from the sun's rays.
The Evolution of Modern Sun Lenses
The explicit development of lenses for sun protection is a more modern development. Early uses of tinted lenses focused on vision correction or, in some cases, as fashionable novelty items. While Ayscough's tinted lenses laid some groundwork for modern sunglasses, they were not designed with the specific intent of filtering or blocking the sun's rays to reduce glare and prevent damage, like sun lenses are today. The provided reference specifically points to James Ayscough as the developer of colored lens, but not as the "creator" of what we know today as sun lenses.
Key Insights
- The first tinted lenses were made from smoky quartz in China around the 12th century.
- James Ayscough created blue and green tinted lenses, but for vision correction, not sun protection, in 1752.
Therefore, while the history of tinted lenses is long and varied, the deliberate creation of sun lenses is a more recent development. The reference provided focuses on the development of tinted lenses but doesn't pinpoint the exact inventor of modern sun lenses.
