James Ayscough, an 18th-century English optician, is credited with pioneering the development of sunglasses. Around 1752, Ayscough introduced spectacles with double-hinged side pieces and began experimenting with tinted lenses, primarily in blue and green hues.

Ayscough’s intent was not solely for fashion, but rather to address specific vision problems and provide therapeutic benefits. He believed that these colored lenses could help individuals who were sensitive to light, a condition that could be exacerbated by various ailments, including syphilis.

While Ayscough’s innovations did not immediately lead to the modern concept of sunglasses, his work laid the foundation for future advancements in eyewear. It wasn’t until the 20th century that sunglasses gained widespread popularity, with Sam Foster mass-producing them in 1929 and making them accessible to the general public.

Today, sunglasses have evolved significantly, offering not only fashion but also essential protection against harmful UV rays and enhanced visual clarity through polarized lenses. Ayscough’s pioneering efforts in the 18th century paved the way for these advancements, ensuring that his legacy continues to be felt in the world of eyewear.
