The Evolution of Eyeglass Lenses in the 1700s: A Look Back in Time
In the 1700s, eyeglasses were becoming more widely used as people began to realize the benefits of clear vision. However, the lenses used then were quite different from what we have today. Let’s take a look back in time to see how eyeglass lenses have evolved over the centuries.
In the early 1700s, eyeglasses were made using convex lenses, which magnify objects and make them appear larger. These lenses were typically made of glass and were quite thick, heavy, and costly. Only the wealthiest members of society could afford them.
As time passed, eyeglass lenses began to improve. In the mid-1700s, Benjamin Franklin invented bifocal lenses, which allowed people to see clearly both near and far. This advancement made eyeglasses more practical, and more people began to use them. Later, in the late 1700s, eyeglass lenses made of crown glass became more widely available. Crown glass was easier to manufacture and was less expensive than other types of glass, making eyeglasses more affordable for the average person.
Fast forward to today, and we have come a long way in the world of eyeglass lenses. Modern lenses are made from a variety of materials, including polycarbonate, high-index plastic, and Trivex. These materials are lighter, thinner, and more impact-resistant than glass lenses, making them a better choice for everyday use. Additionally, advancements in technology have allowed for specialized lenses, such as progressive lenses for those who need different prescriptions for reading and distance vision, and transition lenses that darken in response to sunlight.
