In 1784, Benjamin Franklin invented bifocals. These glasses allowed for vision correction for both near and far vision assistance within one frame. This later led to trifocals, and both bi- and trifocals became increasingly popular in the early 1900s. Today, glasses are very different from the vision correction pieces of the past. For starters, plastic is more readily used in eyeglasses, as this material is less likely to shatter or break. This also allows frames to be lightweight. The Vision Council reports that about 164 million American adults wear eyeglasses, and thanks to innovators scrambling for better sight, they no longer have to squint or hold glass to their face just to see.
Later, people across Europe and China inserted magnifying glasses into frames or held the frames up to their faces or what they were looking at for better vision. For centuries, people also fashioned ribbon ties around their heads to hold their frames in place. In 1352, the first painting depicting spectacles was created by Tommaso da Modena, and these tools only continued to become more popular from there. As vision correction standards improved, frames were soon created with posts on either end, which would sit on the user’s ear. This eliminated the need for ribbon, or holding the frames
If you can read this article, you may be doing so with perfect vision or the aid of some form of corrective eyewear. For centuries, humans have toiled over how to best modify the vision of those who are impaired, resulting in a complex, winding history for eyeglasses. The first recorded instance of glasses being used for better vision is attributed to Roger Bacon in 1268, according to Britannica, but civilizations have long had their own methods for better sight. For example, the Romans used glass globes of water — which they discovered would increase the size of what they were looking at — to improve vision, while the Vikings were said to fashion lenses out of crystals.
