What Was The Purpose Of Bifocals?
Bifocals serve a dual purpose in vision correction. They feature a combination of lenses designed to address both distance vision and close-up tasks like reading. The top portion of the lens is tailored to enhance clarity for distant objects, while the lower portion is specifically crafted to facilitate reading or other activities that require up-close focus. This innovative eyewear design caters to individuals who require assistance with multiple aspects of their vision, offering a seamless transition between tasks without the need to switch between different pairs of glasses.

In response to this challenge, he innovatively created a set of eyeglasses that not only served as regular eyewear but also doubled as reading aids. This groundbreaking invention marked the birth of bifocal glasses, a significant advancement in eyewear technology. By designing these dual-purpose glasses, Franklin not only improved his own visual comfort but also left a lasting legacy in the world of optics, offering a practical solution for individuals facing similar visual challenges.
When Did Benjamin Franklin Invent Bifocals?
